Method Detail

isRecessiveElementInConflict

protected boolean isRecessiveElementInConflict(AbstractMergeableElement re,
                                               java.lang.String eltName)

Deprecated. use isRecessiveElementInConflict(AbstractMergeableElement,List) instead.

Detects if there was a conflict, that is the specified element was present in both dominant and recessive element-sets.

This delegates to isRecessiveElementInConflict(AbstractMergeableElement,List).

Parameters:

re - Recessive element.

eltName - Element name to test for.

Returns:

true if there was a conflict of element.

isRecessiveElementInConflict

protected boolean isRecessiveElementInConflict(AbstractMergeableElement re,
                                               java.util.List eltNameList)

Detects if there was a conflict, that is the specified element was present in both dominant and recessive element-sets.

Use this to determine conflicts when the Dominant and Recessive element sets are keyed with Composite keys.
For instance: <component> is keyed on <role> and <role-hint>.

Parameters:

re -

eltNameList - List of elements that will be checked for values in both dominant and recessive sets.

Returns:

mergeableElementComesFromRecessive

protected boolean mergeableElementComesFromRecessive(AbstractMergeableElement re,
                                                     java.lang.String eltName)

Determines if the Element to be merged is to be sourced from Recessive Element set.

Parameters:

re - Recessive element.

eltName - Element name to test for.

Returns:

merge

public void merge(Mergeable me,
                  MergeStrategy strategy)
           throws MergeException

Simply delegate to

Parameters:

me - Recessive Mergeable instance.

strategy - MergeStrategy to apply for merging.

Throws:

MergeException - if there was an error while merging.
