org.mycore.mods.merger.MCRCategoryMerger

public class MCRCategoryMerger
extends MCRMerger

Merges MODS elements that represent a classification category. When those elements represent two categories A and B, and B is a child of A in the classification tree, B should win and be regarded the more detailed information, while A should be ignored. When property MCR.MODS.Merger.CategoryMerger.Repeatable.[ClassID]=false is set, there can be only one category for this classification, so the first element that occurs wins. Default is "true", meaning the classification is repeatable.

Method Details

isProbablySameAs

public boolean isProbablySameAs(MCRMerger other)

Description copied from class: MCRMerger

Returns true, if the element wrapped by this merger probably represents the same information as the other. The default implementation returns false and may be overwritten by subclasses implementing logic for specific MODS elements.

Overrides:

isProbablySameAs in class MCRMerger

mergeFrom

public void mergeFrom(MCRMerger other)

Description copied from class: MCRMerger

Merges the contents of the element wrapped by the other merger into the contents of the element wrapped by this merger. Should only be called if this.isProbablySameAs(other). The default implementation copies all attributes from the other into this if they do not exist in this element. Afterwards it recursively builds mergers for all child elements and compares and eventually merges them too.

Overrides:

mergeFrom in class MCRMerger
