Detailed Description

This is an interface which serves as a base class for meta data store merge strategy. This is used to decide which entries of a metadata store is kept, or how they are modified when a list of meta data stores are merged together.

Member Function Documentation

description()

virtual QString KisMetaData::MergeStrategy::description ( ) const

pure virtual

Returns

a description of this merge strategy

Implemented in KisMetaData::DropMergeStrategy, KisMetaData::PriorityToFirstMergeStrategy, KisMetaData::OnlyIdenticalMergeStrategy, and KisMetaData::SmartMergeStrategy.

id()

virtual QString KisMetaData::MergeStrategy::id ( ) const

pure virtual

Returns

the id of this merge strategy

Implemented in KisMetaData::DropMergeStrategy, KisMetaData::PriorityToFirstMergeStrategy, KisMetaData::OnlyIdenticalMergeStrategy, and KisMetaData::SmartMergeStrategy.

merge()

virtual void KisMetaData::MergeStrategy::merge ( Store * dst, QList< const Store * > srcs, QList< double > scores ) const

pure virtual

Call this function to merge a list of meta data stores in one.

Parameters

dst	the destination store
srcs	the list of source meta data store
scores	a list of score which defines the importance of each store compared to the other the sum of score is expected to be equal to 1.0. One way to attribute a score is to compute the area of each layer and then to give a higher score to the biggest layer. srcs and scores list must have the same size.

Implemented in KisMetaData::DropMergeStrategy, KisMetaData::PriorityToFirstMergeStrategy, KisMetaData::OnlyIdenticalMergeStrategy, and KisMetaData::SmartMergeStrategy.

name()

virtual QString KisMetaData::MergeStrategy::name ( ) const

pure virtual

Returns

the name of this merge strategy

Implemented in KisMetaData::DropMergeStrategy, KisMetaData::PriorityToFirstMergeStrategy, KisMetaData::OnlyIdenticalMergeStrategy, and KisMetaData::SmartMergeStrategy.
