Detailed Description

Utility class for merging work item attributes. Stores a list of patterns and operations that determine how attributes should be merged. The array order determines the order the patterns are applied.

Definition at line 34 of file PDG_AttributeMerge.h.

Member Typedef Documentation

using PDG_AttributeMerge::Pattern = UT_Array<UT_UniquePtr<MergeData>>

A collection of merge patterns.

Definition at line 96 of file PDG_AttributeMerge.h.

Member Enumeration Documentation

enum PDG_AttributeMerge::AttribFlatten

Enumeration of different flatten operations, which determines if the dynamic and static attribute maps of the source should be combined.

Enumerator
eAttribFlattenNever	Never flatten the attribute maps.
eAttribFlattenAlways	Always flatten the attribute maps.
eAttribFlattenContext	Use the context runtime state to determine if the maps should be flattened

Definition at line 58 of file PDG_AttributeMerge.h.

enum PDG_AttributeMerge::AttribType

Enumeration of types of data types to merge.

Enumerator
eAttribRegular	Merge operation should include regular attributes, which are all attributes except for inputs and outputs.
eAttribInput	Merge operation should copy incoming output files to the dest map's input file attrib
eAttribOutput	Merge operation should copy incoming output files to the dest map's output file attrib
eAttribAll	Convenience value for merging all attribute types.

Definition at line 38 of file PDG_AttributeMerge.h.

Constructor & Destructor Documentation

PDG_AttributeMerge::PDG_AttributeMerge	(	int	attribute_types,
