getResolvedEntity
Implements the guts of theresolveEntity
method for the SAX interface.Presented with an optional public identifier and a system identifier, this function attempts to locate a mapping in the catalogs.
If such a mapping is found, it is returned. If no mapping is found, null is returned.
- Parameters:
publicId
- The public identifier for the entity in question. This may be null.systemId
- The system identifier for the entity in question. XML requires a system identifier on all external entities, so this value is always specified.- Returns:
- The resolved identifier (a URI reference).
-
resolveEntity
Implements theresolveEntity
method for the SAX interface.Presented with an optional public identifier and a system identifier, this function attempts to locate a mapping in the catalogs.
If such a mapping is found, the resolver attempts to open the mapped value as an InputSource and return it. Exceptions are ignored and null is returned if the mapped value cannot be opened as an input source.
If no mapping is found (or an error occurs attempting to open the mapped value as an input source), null is returned and the system will use the specified system identifier as if no entityResolver was specified.
- Specified by:

- Parameters:
publicId
- The public identifier for the entity in question. This may be null.systemId
- The system identifier for the entity in question. XML requires a system identifier on all external entities, so this value is always specified.- Returns:
