Method Detail

NewInstance

public static DefaultMergeStrategy NewInstance(Class<? extends CdmBase> mergeClazz)

getUuid

protected UUID getUuid()

Specified by:

getUuid in class StrategyBase

getMergeClass

public Class<? extends CdmBase> getMergeClass()

Returns:

the merge class

setMergeClazz

public void setMergeClazz(Class<? extends CdmBase> mergeClazz)

Parameters:

mergeClazz - the mergeClazz to set

getMergeMode

public MergeMode getMergeMode(String propertyName)

Specified by:

getMergeMode in interface IMergeStrategy

setMergeMode

public void setMergeMode(String propertyName,
                         MergeMode mergeMode)
                  throws MergeException

Description copied from interface: IMergeStrategy

Sets the merge mode for property propertyName

Specified by:

setMergeMode in interface IMergeStrategy

Throws:

MergeException

invoke

public <T extends IMergable> Set<ICdmBase> invoke(T mergeFirst,
                                                  T mergeSecond)
                     throws MergeException

Description copied from interface: IMergeStrategy

Merges mergeSecond into mergeFirst. Returns a set of CdmBases that became orphant during the merge process and therefore must be deleted from a persistent context.

Specified by:

invoke in interface IMergeStrategy

Throws:

MergeException

invoke

public <T extends IMergable> Set<ICdmBase> invoke(T mergeFirst,
                                                  T mergeSecond,
                                                  Set<ICdmBase> clonedObjects)
                     throws MergeException

Description copied from interface: IMergeStrategy

Merges mergeSecond into mergeFirst. Returns a set of CdmBases that became orphant during the merge process and therefore must be deleted from a persistent context.

Specified by:

invoke in interface IMergeStrategy

clonedObjects - a set of objects that needed to be cloned during merge. This set will be filled during merge and should preferably be empty at the beginning

Throws:

MergeException

Throws:

MergeException

getMergeValue

protected <T extends IMergable> Object getMergeValue(T mergeFirst,
                                                     T mergeSecond,
                                                     Field field)
