Detailed Description

An abstract base class for executors, which do not store any data at all. This class mainly serves the purpose of abstracting away error handling on dataless executors, when methods that are supposed to mutate data are called.

Member Function Documentation

virtual void VdfDatalessExecutor::_ClearData ( )

inlineoverrideprotectedvirtual

Clears all the data caches associated with any output in the network.

This has no effect on this type of executor.

Reimplemented from VdfExecutorInterface.

Reimplemented in EfMaskedSubExecutor.

Definition at line 111 of file datalessExecutor.h.

void VdfDatalessExecutor::_ClearDataForOutput	(	const VdfId	outputId,
		const VdfId	nodeId
	)

inlineoverrideprotectedvirtual

Clears the data for a specific output on this executor.

This has no effect on this type of executor.

Reimplemented from VdfExecutorInterface.

Definition at line 104 of file datalessExecutor.h.

virtual const VdfVector* VdfDatalessExecutor::_GetInputValue	(	const VdfConnection &	connection,
		const VdfMask &	mask
	)		const

inlineoverrideprotectedvirtual

Returns a value for the cache that flows across connection.

Implements VdfExecutorInterface.

Definition at line 79 of file datalessExecutor.h.

virtual const VdfVector* VdfDatalessExecutor::_GetOutputValueForReading	(	const VdfOutput &	output,
		const VdfMask &	mask
	)		const

inlineoverrideprotectedvirtual

Returns an output value for reading.

Implements VdfExecutorInterface.

Definition at line 87 of file datalessExecutor.h.

virtual VdfVector* VdfDatalessExecutor::_GetOutputValueForWriting ( const VdfOutput & output ) const

inlineoverrideprotectedvirtual

Returns an output value for writing.

Implements VdfExecutorInterface.

Definition at line 95 of file datalessExecutor.h.

virtual VDF_API void VdfDatalessExecutor::_SetReferenceOutputValue	(	const VdfOutput &	destOutput,
		const VdfOutput &	sourceOutput,
		const VdfMask &	sourceMask
	)		const

overrideprotectedvirtual

Called to set destOutput's buffer output to be a reference to the buffer output of sourceOutput.

This is not supported on this type of executor.

Implements VdfExecutorInterface.

virtual void VdfDatalessExecutor::_TouchOutput ( const VdfOutput & output ) const

inlineoverrideprotectedvirtual

Mark the output as having been visited. This is only to be used by the speculation engine to tell its parent executor that an output has been visited and should be marked for invalidation.

This has no effect on this type of executor.

Implements VdfExecutorInterface.

Definition at line 138 of file datalessExecutor.h.

virtual void VdfDatalessExecutor::_UpdateInvalidationTimestamp ( )

inlineoverrideprotectedvirtual

Called before invalidation begins to update the timestamp that will be written for every VdfOutput visited during invalidation. This timestamp is later used to identify outputs for mung buffer locking.

This has no effect on this type of executor.

Implements VdfExecutorInterface.

Definition at line 119 of file datalessExecutor.h.

virtual bool VdfDatalessExecutor::IsEmpty ( ) const

inlineoverridevirtual

Returns true of the data manager is empty.

This type of executor is always considered empty, since it does not hold any data.

Implements VdfExecutorInterface.

Reimplemented in EfMaskedSubExecutor.

Definition at line 66 of file datalessExecutor.h.
