Parameters:

pool - Instance shared broker pool.

Method Detail

getAllResults

public List getAllResults(Sequence sequence)

Convert sequence into list of strings. Java5 would make this method more safe to use.

Parameters:

sequence - Result of query.

Returns:

List containing String objects.

getFirstResult

public String getFirstResult(Sequence sequence)

Get first entry of sequence as String. Java5 would make this method more safe to use.

Parameters:

sequence - Result of query.

Returns:

String containing representation of 1st entry of sequence.

executeQuery

public Sequence executeQuery(XmldbURI collection,
                             Map params,
                             String queryPath)

Execute query with supplied parameters. namespace, publicId, catalogPath,

Parameters:

collection - Collection in which query is executed.

params - Map of parameters used in cquery

queryPath - Path to xquery in classpath

Returns:

Result of xQuery

getSchemaPath

public String getSchemaPath(XmldbURI collection,
                            String namespace)

Find document path of XSD describing a namespace.

Parameters:

collection - Start point for search, e.g. '/db'.

namespace - Namespace that needs to be found.

Returns:

Document path (e.g. '/db/foo/bar.xsd') if found, null if namespace could not be found.

getDtdPath

public String getDtdPath(XmldbURI collection,
                         String publicId)
