Field Summary

Fields

Modifier and Type	Field and Description
static String	CHILDREN_COMBINATION_APPEND
static String	CHILDREN_COMBINATION_MERGE
static String	CHILDREN_COMBINATION_MODE_ATTRIBUTE
static String	DEFAULT_CHILDREN_COMBINATION_MODE This default mode for combining children DOMs during merge means that where element names match, the process will try to merge the element data, rather than putting the dominant and recessive elements (which share the same element name) as siblings in the resulting DOM.
static String	DEFAULT_SELF_COMBINATION_MODE This default mode for combining a DOM node during merge means that where element names match, the process will try to merge the element attributes and values, rather than overriding the recessive element completely with the dominant one.
static String	SELF_COMBINATION_MERGE
static String	SELF_COMBINATION_MODE_ATTRIBUTE
static String	SELF_COMBINATION_OVERRIDE

DEFAULT_SELF_COMBINATION_MODE

public static final String DEFAULT_SELF_COMBINATION_MODE

This default mode for combining a DOM node during merge means that where element names match, the process will try to merge the element attributes and values, rather than overriding the recessive element completely with the dominant one. This means that wherever the dominant element doesn't provide the value or a particular attribute, that value or attribute will be set from the recessive DOM node.

Method Detail

writeToSerializer

public void writeToSerializer(String namespace,
                     XmlSerializer serializer,
                     Xpp3Dom dom)
                       throws IOException

Throws:

IOException

mergeXpp3Dom

public static Xpp3Dom mergeXpp3Dom(Xpp3Dom dominant,
                   Xpp3Dom recessive,
                   Boolean childMergeOverride)

Merge two DOMs, with one having dominance in the case of collision.

Parameters:

dominant - The dominant DOM into which the recessive value/attributes/children will be merged

recessive - The recessive DOM, which will be merged into the dominant DOM

childMergeOverride - Overrides attribute flags to force merging or appending of child elements into the dominant DOM

See Also:

CHILDREN_COMBINATION_MODE_ATTRIBUTE, SELF_COMBINATION_MODE_ATTRIBUTE

mergeXpp3Dom

public static Xpp3Dom mergeXpp3Dom(Xpp3Dom dominant,
                   Xpp3Dom recessive)

Merge two DOMs, with one having dominance in the case of collision. Merge mechanisms (vs. override for nodes, or vs. append for children) is determined by attributes of the dominant root node.

Parameters:

dominant - The dominant DOM into which the recessive value/attributes/children will be merged

recessive - The recessive DOM, which will be merged into the dominant DOM

CHILDREN_COMBINATION_MODE_ATTRIBUTE, SELF_COMBINATION_MODE_ATTRIBUTE
