Constructor & Destructor Documentation

PDG_PartitionHolder::PDG_PartitionHolder

(

const PDG_WorkItemArray &

work_item

)

Constructs a new partition holder with a list of valid work items.

Member Function Documentation

bool PDG_PartitionHolder::addItemToAllPartitions	(	PDG_WorkItem *	work_item,
		UT_WorkBuffer &	errors
	)

Adds a work item to all partitions, without having to know the indices or number of partitions that exist

bool PDG_PartitionHolder::addItemToPartition	(	PDG_WorkItemID	id,
		int	index,
		bool	required,
		UT_WorkBuffer &	errors
	)

Adds a work item to the partition with the specified index.

Examples:

PDG/PDG_PartitionByParity.C.

bool PDG_PartitionHolder::addItemToPartition	(	PDG_WorkItem *	work_item,
		int	index,
		bool	required,
		UT_WorkBuffer &	errors
	)

Adds a work item to the partition with the specified index.

bool PDG_PartitionHolder::addItemToPartition	(	PDG_WorkItem *	work_item,
		const UT_StringHolder &	name,
		bool	required,
		UT_WorkBuffer &	errors
	)

Adds a work item to the partition with the specified name.

const PDG_WorkItemIDSet& PDG_PartitionHolder::allSet ( ) const

inline

Returns the all set, e.g. the set of items that should be added to all partitions

Definition at line 81 of file PDG_PartitionHolder.h.

bool PDG_PartitionHolder::checkLoop	(	UT_WorkBuffer &	errors,
		const PDG_WorkItemIDSet &	ids,
		PDG_WorkItem **	current_item,
		bool	check_all
	)		const

Determines the loop stack work item for a set of work item IDs, and returns false if the IDs don't form a valid partition for a loop.

bool PDG_PartitionHolder::checkLoop	(	UT_WorkBuffer &	errors,
		const PDG_WorkItemArray &	work_items,
		PDG_WorkItem **	current_item
	)		const

Determines the loop stack work item for a list of work items, and return false if the items don't form a valid partition for a loop

PDG_OptionalFrame PDG_PartitionHolder::frameForPartition

(

int

index

)

const

Return the frame specified for the partition with the given index.

bool PDG_PartitionHolder::isAllSetOnly

(

)

const

Returns true if the holder only consists of entries in the All Set.

bool PDG_PartitionHolder::isSplitting ( ) const

inline

Returns true if this holder is being used for partitioning with a split attribute.

Definition at line 104 of file PDG_PartitionHolder.h.

int PDG_PartitionHolder::maxIndex ( ) const

inline

Returns the current max index of all partitions added to the holder.

Definition at line 86 of file PDG_PartitionHolder.h.

int PDG_PartitionHolder::numPartitions ( ) const

inline

Returns the number of partitions added to the holder. This is reset after setSplitValue is called.

Definition at line 91 of file PDG_PartitionHolder.h.

PDG_WorkItem* PDG_PartitionHolder::partitionInput ( PDG_WorkItemID  id ) const

inline

Returns the input work item for the specifed ID, or null if the ID is not a valid input

Definition at line 116 of file PDG_PartitionHolder.h.

const IndexMap& PDG_PartitionHolder::partitions ( ) const

inline

Returns the partition map.

Definition at line 72 of file PDG_PartitionHolder.h.

const IndexMap& PDG_PartitionHolder::required ( ) const

inline

Returns the items that should be marked as required for each partition.

Definition at line 76 of file PDG_PartitionHolder.h.

void PDG_PartitionHolder::resolveNames

(

)

Converts named partitions into real partitions.

void PDG_PartitionHolder::setPartitionFrame	(	int	index,
		fpreal	frame
	)

Sets the frame for the partition with the given index.

void PDG_PartitionHolder::setPartitionFrame	(	const UT_StringHolder &	name,
		fpreal	frame
	)

Sets the frame for the partition with the given name.

void PDG_PartitionHolder::setSplitInfo

(

const UT_StringHolder &

name

)

Sets the global split attribute information for this holder. Called once during partitioning with a split attribute.

void PDG_PartitionHolder::setSplitValue	(	const UT_StringHolder &	value,
		int	index_offset
	)

Sets the local split attribute information for this holder. Called once for each split attribute value during partitioning.

const UT_StringHolder& PDG_PartitionHolder::splitAttribute ( ) const

inline

Returns the split attribute name.

Definition at line 95 of file PDG_PartitionHolder.h.

const PDG_WorkItemArray& PDG_PartitionHolder::splitMissing ( ) const

inline

Returns the array of work items that are missing the split attribute, or nullptr if isSplitting() returns false;

Definition at line 109 of file PDG_PartitionHolder.h.

PDG_WorkItemArray& PDG_PartitionHolder::splitMissing ( )

inline

Definition at line 111 of file PDG_PartitionHolder.h.

const UT_StringHolder& PDG_PartitionHolder::splitValue ( ) const

inline

Returns the current split attribute value.

Definition at line 99 of file PDG_PartitionHolder.h.
