Detailed Description

Contains data structures necessary to implement exec requests that are independent of scene description.

Concrete implementations inherit from Exec_RequestImpl to implement any functionality that is specific to the scene description system.

Member Function Documentation

_Compile()

EXEC_API void _Compile ( TfSpan< const ExecValueKey >  valueKeys )

protected

Compiles outputs for the value keys in the request.

_Compute()

EXEC_API Exec_CacheView _Compute ( )

protected

Computes the value keys in the request.

_Discard()

EXEC_API void _Discard ( )

protected

Removes the request from the system.

This prevents any further notification and releases internal request data structures.

_ExpireIndices()

EXEC_API void _ExpireIndices ( const ExecRequestIndexSet &  expired )

protected

Expires the indices in expired.

Invalidation callbacks will be invoked for these indices one final time. No values will be extractable and no further invalidation will be sent for these indices.

_RequiresCompilation()

EXEC_API bool _RequiresCompilation ( ) const

protected

Returns true if the request needs to be compiled.

A request may skip compilation if its schedule is up-to-date and there is no pending recompilation in the network.

_Schedule()

EXEC_API void _Schedule ( )

protected

Builds the schedule for the request.

DidChangeTime()

void DidChangeTime

(

const Exec_TimeChangeInvalidationResult &

invalidationResult

)

Notify the request of time having changed.

DidInvalidateComputedValues() [1/3]

void DidInvalidateComputedValues

(

const Exec_AttributeValueInvalidationResult &

invalidationResult

)

Notify the request of invalid computed values as a consequence of attribute authored value invalidation.

DidInvalidateComputedValues() [2/3]

void DidInvalidateComputedValues

(

const Exec_DisconnectedInputsInvalidationResult &

invalidationResult

)

Notify the request of invalid computed values as a consequence of uncompilation.

DidInvalidateComputedValues() [3/3]

void DidInvalidateComputedValues

(

const Exec_MetadataInvalidationResult &

invalidationResult

)

Notify the request of invalid computed values as a consequence of metadata authored value invalidation.

Expire()

void Expire

(

)

Expires all request indices and discards the request.

Sends value invalidation for all indicies over all time and renders the request unusuable for any future operation.
