Method Detail

setSource

public void setSource(java.lang.Object source)
Set the configuration source Object for this metadata element.

The exact type of the object will depend on the configuration mechanism used.


getSource

public java.lang.Object getSource()
Description copied from interface: BeanMetadataElement
Return the configuration source Object for this metadata element (may be null).

Specified by:
getSource in interface BeanMetadataElement

setMergeEnabled

public void setMergeEnabled(boolean mergeEnabled)
Set whether merging should be enabled for this collection, in case of a 'parent' collection value being present.


isMergeEnabled

public boolean isMergeEnabled()
Description copied from interface: Mergeable
Is merging enabled for this particular instance?

Specified by:
isMergeEnabled in interface Mergeable

merge

public java.lang.Object merge(java.lang.Object parent)
Description copied from interface: Mergeable
Merge the current value set with that of the supplied object.

The supplied object is considered the parent, and values in the callee's value set must override those of the supplied object.
