Examples with MCRMetaInterface org.mycore.datamodel.metadata.MCRMetaInterface used on opensource projects

Example 1 with MCRMetaInterface

use of org.mycore.datamodel.metadata.MCRMetaInterface in project mycore by MyCoRe-Org.

the class MCRObjectMerger method mergeMetadata.

/**
 * Merges the metadata of the given source into the target object. Be aware that
 * performance isn't that good when validation is activated, due checking against
 * the schema each time a change is made.
 *
 * @param source the source which is merged into the target
 * @param validate If true, every change is tracked and validated against the
 *          xml schema of the mycore object. When a change is invalid it will be
 *          canceled and the merging continues.
 *          When set to false the mycore object will be merged without validation.
 *          This can result in an invalid object.
 *
 * @return true if something was merged
