getLazyStore

StructuredStore getLazyStore(String indexConfigPath,
                             String indexName,
                             String sourcePath,
                             Templates preFilter,

                      throws IOException

Search for a StructuredStore containing the "lazy" or persistent representation of a given document. Index parameters are specified, since often the lazy file is stored along with the index. This method is called first, and if it returns null, then getInputSource(String, boolean) will be called as a fall-back.

Parameters:

sourcePath - Path to the source document

indexConfigPath - Path to the index configuration file

indexName - Name of the index being searched

preFilter - Stylesheet to filter the document with

removeDoctypeDecl - Set to true to remove DOCTYPE declaration from the XML document.

Returns:

Store containing the tree, or null if none could be found.

Throws:

IOException

getInputSource

InputSource getInputSource(String sourcePath,
                           boolean removeDoctypeDecl)
                    throws IOException

Retrieve the data stream for an XML source document.

Parameters:

sourcePath - Path to the source document

removeDoctypeDecl - Set to true to remove DOCTYPE declaration from the XML document.

Returns:

Data stream for the document.
