Detailed Description

template<class T>
class OpenSim::Set< T >

A class for holding a set of pointers to objects.

It is derived from class Object and is implemented as a wrapper around template ArrayPtrs<T>. It is implemented around an array of pointers, rather than values, so that it can make use of any virtual methods associated with class T.

inlinevirtual
template<class T>
virtual bool OpenSim::Set< T >::cloneAndAppend ( const T &  aObject)
inlinevirtual

cloneAndAppend creates a clone of the passed in object and appends the clone to the array.

The original object is unaffected and is not associated with the Set. The clone is created using the method clone() available to OpenSim::Object

Parameters
aObjectObject whose clone is to be appended.
Returns
True if the append was successful, false otherwise.
template<class T>
bool OpenSim::Set< T >::computeNewCapacity ( int  aMinCapacity,
int &  rNewCapacity 
)
inline

Compute a new capacity that is at least as large as a specified minimum capacity; this method does not change the capacity, it simply computes a new recommended capacity.

If the capacity increment is negative, the current capacity is doubled until the computed capacity is greater than or equal to the specified minimum capacity. If the capacity increment is positive, the current capacity increments by this amount until the computed capacity is greater than or equal to the specified minimum capacity. If the capacity increment is zero, the computed capacity is set to the current capacity and false is returned.

Parameters
rNewCapacityNew computed capacity.
aMinCapacityMinimum new computed capacity. The computed capacity is incremented until it is at least as large as aMinCapacity, assuming the capacity increment is not zero.
Returns
True if the new capacity was increased, false otherwise (i.e., if the capacity increment is set to 0).

inline

Get the number of groups.

template<class T>
int OpenSim::Set< T >::getSize ( ) const

virtual bool OpenSim::Set< T >::insert ( int  aIndex,
T *  aObject 
)
inlinevirtual

Insert an object into the array at a specified index.

A copy of the specified object is NOT made. If getMemoryOwner() is true, this Set takes over ownership of the object and deletes it when the Set itself is deleted.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters
aObjectObject to be inserted.
aIndexIndex at which to insert the new object. All current elements from aIndex to the end of the array are shifted one place in the direction of the end of the array. The specified index must be less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the insertion is equivalent to an append.
Returns
True if the insertion was successful, false otherwise.

Reimplemented in OpenSim::ModelComponentSet< T >, OpenSim::ModelComponentSet< ExternalForce >, OpenSim::ModelComponentSet< ContactGeometry >, OpenSim::ModelComponentSet< Coordinate >, OpenSim::ModelComponentSet< Force >, OpenSim::ModelComponentSet< Joint >, OpenSim::ModelComponentSet< Probe >, OpenSim::ModelComponentSet< Controller >, OpenSim::ModelComponentSet< ModelComponent >, OpenSim::ModelComponentSet< Body >, OpenSim::ModelComponentSet< Constraint >, and OpenSim::ForceSet.

template<class T>
virtual bool OpenSim::Set< T >::insert ( int  aIndex,
const T &  aObject 
)
inlinevirtual

Insert an object into the array at a specified index.

A copy is made of the object and added to the Set. The original object is unaffected.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters
aObjectObject to be inserted.
aIndexIndex at which to insert the new object. All current elements from aIndex to the end of the array are shifted one place in the direction of the end of the array. The specified index must be less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the insertion is equivalent to an append.
Returns
True if the insertion was successful, false otherwise.
template<class T>
Set<T>& OpenSim::Set< T >::operator= ( const Set< T > &  aSet)
inline

Assign this set to another set.

This operator makes a complete copy of the specified set; all member variables and objects in the set are copied. Because all objects are copied, this set takes ownership of the newly allocated objects (i.e., _memoryOwner is set to true. So, the result is two independent, identical sets, with the possible exception of the _memoryOwner flag.

Parameters
aSetSet to be copied.
Returns
Reference to this set.
template<class T>
T& OpenSim::Set< T >::operator[] ( int  aIndex) const
inline

Get a pointer to the set object at a specified index.

This operator is intended for accessing set objects with as little overhead as possible, so no error checking is performed. The caller must make sure the specified index is within the bounds of the array. If error checking is desired, use ArrayPtrs::get().

Parameters
aIndexIndex of the desired element (0 <= aIndex < _size).
Returns
Reference to the array element.
Exceptions
Exceptionif a NULL pointer is encountered.
See Also
get().
template<class T>
virtual bool OpenSim::Set< T >::remove ( int  aIndex)
inlinevirtual

Remove an object from the array at a specified index.

If this set is set as the memory owner, the object is deleted when it is removed.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters
aIndexIndex of the value to remove. All elements from aIndex to the end of the array are shifted one place toward the beginning of the array. If aIndex is less than 0 or greater than or equal to the current size of the array, no element is removed.
Returns
True if the removal was successful, false otherwise.

Reimplemented in OpenSim::ForceSet.

template<class T>
virtual bool OpenSim::Set< T >::remove ( const T *  aObject)
inlinevirtual

Remove an object from the array by specifying its address.

The object is deleted when it is removed.

This method is relatively computationally costly since many of the array elements may need to be shifted.

Parameters
aObjectPointer to the object to be removed. If an object with the specified address is not found, no action is taken.
Returns
True if the removal was successful, false otherwise.
template<class T>
void OpenSim::Set< T >::removeGroup ( const std::string &  aGroupName)
inline

Remove a group from the set.

Elements are not removed.

template<class T>
void OpenSim::Set< T >::renameGroup ( const std::string &  oldGroupName,
const std::string &  newGroupName 
)
inline

Rename a group.

template<class T>
int OpenSim::Set< T >::searchBinary ( const T &  aObject,
bool  aFindFirst = false,
int  aLo = -1,
int  aHi = -1 
) const
inline

Search for the largest value in the array that is less than or equal to a specified value.

If there is more than one element with this largest value, the index of the first of these elements can optionally be found, but this can be up to twice as costly.

This method assumes that the array element values monotonically increase as the array index increases. Note that monotonically increase means never decrease, so it is permissible for adjacent elements to have the same value.

A binary search is performed (i.e., the array is repeatedly subdivided into two bins one of which must contain the specified until the approprite element is identified), so the performance of this method is approximately ln(n), where n is the size of the array.

Parameters
aValueValue to which the array elements are compared.
aFindFirstIf true, find the first element that satisfies the search. If false, the index of any element that satisfies the search can be returned- which index will be returned depends on the length of the array and is therefore somewhat arbitrary. By default, this flag is false.
aLoLowest array index to consider in the search.
aHiHighest array index to consider in the search.
Returns
Index of the array element that has the largest value that is less than or equal to aValue. If there is more than one such elements with the same value and aFindFirst is set to true, the index of the first of these elements is returned. If an error is encountered (e.g., the array is empty), or the array contains no element that is less than or equal to aValue, -1 is returned.
template<class T>
virtual bool OpenSim::Set< T >::set ( int  aIndex,
T *  aObject,
bool  preserveGroups = false 
)
inlinevirtual

Set the object at a specified index.

A copy of the object is NOT made. If getMemoryOwner() is true, this Set takes over ownership of the object and deletes it when the Set itself is deleted.

Parameters
aIndexIndex of the array element to be set. aIndex must be greater than zero and less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the set is equivalent to an append.
aObjectObject to be set.
preserveGroupsIf true, the new object will be added to the groups that the object it replaces belonged to
Returns
True if the set was successful, false otherwise.

Reimplemented in OpenSim::ModelComponentSet< T >, OpenSim::ModelComponentSet< ExternalForce >, OpenSim::ModelComponentSet< ContactGeometry >, OpenSim::ModelComponentSet< Coordinate >, OpenSim::ModelComponentSet< Force >, OpenSim::ModelComponentSet< Joint >, OpenSim::ModelComponentSet< Probe >, OpenSim::ModelComponentSet< Controller >, OpenSim::ModelComponentSet< ModelComponent >, OpenSim::ModelComponentSet< Body >, and OpenSim::ModelComponentSet< Constraint >.

template<class T>
virtual bool OpenSim::Set< T >::set ( int  aIndex,
const T &  aObject,
bool  preserveGroups = false 
)
inlinevirtual

Set the object at a specified index.

A copy is made of the object and added to the Set. The original object is unaffected.

Parameters
aIndexIndex of the array element to be set. aIndex must be greater than zero and less than or equal to the size of the array. Note that if aIndex is equal to the size of the array, the set is equivalent to an append.
aObjectObject to be set.
preserveGroupsIf true, the new object will be added to the groups that the object it replaces belonged to
Returns
True if the set was successful, false otherwise.
template<class T>
void OpenSim::Set< T >::setCapacityIncrement ( int  aIncrement)
inline

Set the amount by which the capacity is increased when the capacity of of the array in exceeded.

If the specified increment is negative or this method is called with no argument, the capacity is set to double whenever the capacity is exceeded.

Parameters
aIncrementDesired capacity increment.
template<class T>
void OpenSim::Set< T >::setMemoryOwner ( bool  aTrueFalse)
inline

Set whether or not this set owns the memory pointed to by the pointers it holds.

Parameters
aTrueFalseIf true, all the memory associated with each of the pointers in this array are deleted upon the array's destruction. If false, deletes are not issued for each of the pointers.
template<class T>
virtual bool OpenSim::Set< T >::setSize ( int  aSize)
inlinevirtual

Set the size of the array.

This method can be used only to decrease the size of the array. If the size of an array is decreased, all objects in the array that become invalid as a result of the decrease are deleted.

Note that the size of an array is different than its capacity. The size indicates how many valid elements are stored in an array. The capacity indicates how much the size of the array can be increased without allocated more memory. At all times size <= capacity.

Parameters
aSizeDesired size of the array. The size must be greater than or equal to zero and less than or equal to the current size of the array.
Returns
True if the requested size change was carried out, false otherwise.
template<class T>
void OpenSim::Set< T >::setupGroups ( )
inline

Setup groups (match group member names to set members).

template<class T>
void OpenSim::Set< T >::trim ( )
inline

Trim the capacity of this array so that it is one larger than the size of this array.

This is useful for reducing the amount of memory used by this array. This capacity is kept at one larger than the size so that, for example, an array of characters can be treated as a NULL terminated string.

Implementation of the output operator.

The output for a set looks like the following:

Set[size] = T[0] T[1] T[2] ... T[size-1].

Parameters
aOutOutput stream.
aSetSet to be output.
Returns
Reference to the output stream.
