Class FSCatalog

java.lang.Object

com.openhtmltopdf.resource.FSCatalog

public class FSCatalog
extends Object

FSCatalog loads an XML catalog file to read mappings of public IDs for XML schemas/dtds, to resolve those mappings to a local store for the schemas. The catalog file allows one to have a single mapping of schema IDs to local files, and is useful when there are many schemas, or when schemas are broken into many smaller files. Currently FSCatalog only supports the very simple mapping of public id to local URI using the public element in the catalog XML.

FSCatalog is not an EntityResolver; it only parses a catalog file. See FSEntityResolver for entity resolution.

To use, instantiate the class, and call parseCatalog(InputSource) to retrieve a Map keyed by public ids. The class uses an XMLReader instance retrieved via XMLResource.newXMLReader(), so XMLReader configuration (and specification) follows that of the standard XML parsing in Flying Saucer.

This class is not safe for multi-threaded access.
