Method Detail

compareMetadata

public float compareMetadata(org.licas_xml.abs.Element compareWith,
                             org.licas_xml.abs.Element metaStructure,
                             java.lang.String matchType)

Compare the metadata as XML structure and return the result. There are five default structures that get checked, as follows:

1. MetaConst.ANYSTRUCTURE: always returns 1.0.
2. MetaConst.ALLPARTIAL: both element name and value must be present but the exact structure is not required. Returns 1.0 for a full match or 0.5 if values or parts of values are missing.
3. MetaConst.ALLEXACT: both element name and value must be present and the exact structure is also required. Returns 1.0 for a full match or 0.5 if values or parts of values are missing.
4. MetaConst.VALUESPARTIAL: only the value must be present but the exact structure is not required. Returns 1.0 for a full match or 0.5 if values or parts of values are missing.
5. MetaConst.VALUESEXACT: only the value must be present and the exact structure is also required. Returns 1.0 for a full match or 0.5 if values or parts of values are missing.

Parameters:

compareWith - the metadata of the service to compare with.

metaStructure - the metadata that defines the desired structure.

matchType - the type of matching process. If null, then MetaConst.ALLEXACT is used.

Returns:

a value indicating how well the metadata matches.
