Detailed Description

This class is basically a glorified enumerated type, type-safe and range checked but permitting convenient (if limited) arithmetic.

Constants look like Stage::Position, and loops can be written like

for(Stage s = Stage::LowestValid; s <= Stage::HighestValid; ++s) {
// ...
}

Stage constants (of type Stage::Level) are implicitly converted to type Stage when necessary.

Default construction gives Stage::Empty which really means "invalid".

Constructor & Destructor Documentation

SimTK::Stage::Stage ( )
inline

Default construction gives Stage::Empty.

SimTK::Stage::Stage ( Level  l)
inline

This is an implicit conversion from Stage::Level to Stage.

SimTK::Stage::Stage ( int  l)
inlineexplicit

You can explicitly create a Stage from an int if it is in range.

Member Function Documentation

Return the Stage following this one, with Stage::Infinity returned if this Stage is already at its highest value, Stage::Report.

An exception is thrown if this Stage is already Stage::Infinity.

Stage SimTK::Stage::prev ( ) const
inline

Return the Stage before this one, with Stage::Empty returned if this Stage is already at its lowest value, Stage::Topology.

An exception is thrown if this Stage is already Stage::Empty.

String SimTK::Stage::getName ( ) const
inline

Return a printable name corresponding to the stage level currently stored in this Stage.

void SimTK::Stage::invalidate ( Stage  tooHigh)
inline

Set this Stage=min(stageNow, tooHigh-1).

bool SimTK::Stage::isInRuntimeRange ( ) const
inline

Return true if this Stage has one of the meaningful values between Stage::Topology and Stage::Report, rather than one of the end markers Stage::Empty or Stage::Infinity.
