	Stages can use the OnStagePositionChanged callback to signal updates about their position. Some adapters do so, others do not, in which case the UI code should use polling. This function signals whether the device adapters uses callbacks, so that the UI knows it does not need to poll this device. It is best practice to not change the result of this function (i.e. use a const value) as the UI will query the function only once.

Detailed Description

Single axis stage API.

Member Function Documentation

GetFocusDirection()

virtual int MM::Stage::GetFocusDirection ( FocusDirection &  direction )

pure virtual

Return the focus direction.

Indicates whether increasing position corresponds to movement in the direction that brings the objective and sample closer together.

Unless the direction is known for sure (does not depend on e.g. how the hardware is installed), this function must return FocusDirectionUnknown (the application can allow the user to specify the direction as needed).

Non-focus single-axis stages must also return FocusDirectionUnknown.

GetType()

virtual DeviceType MM::Stage::GetType ( ) const

inlinevirtual

Implements MM::Device.

IsStageLinearSequenceable()

virtual int MM::Stage::IsStageLinearSequenceable ( bool &  isSequenceable ) const

pure virtual

Indicate whether the stage can perform linear TTL sequencing.

Linear sequencing uses a delta and count instead of an arbitrary list of positions. If true, the following methods must be implemented: SetStageLinearSequence(), StartStageSequence(), StopStageSequence().

IsStageSequenceable()

virtual int MM::Stage::IsStageSequenceable ( bool &  isSequenceable ) const

pure virtual

Indicate whether the stage can be sequenced (synchronized by TTLs).

If true, the following methods must be implemented: GetStageSequenceMaxLength(), StartStageSequence(), StopStageSequence(), ClearStageSequence(), AddToStageSequence(), and SendStageSequence().

SetStageLinearSequence()

virtual int MM::Stage::SetStageLinearSequence ( double  dZ_um, long  nSlices  )

pure virtual

Set up to perform an equally-spaced triggered Z stack.

After calling this function, StartStageSequence() must cause the stage to step by dZ_um on each trigger. On the Nth trigger, the stage must return to the position where it was when StartStageSequence() was called.
