Method Detail

createQuery

public Query createQuery(String s,
                         String s1)
                  throws javax.jcr.query.InvalidQueryException,
                         javax.jcr.RepositoryException

Description copied from interface: QueryManager

Description inherited from javax.jcr.query.QueryManager#createQuery(String, String)
Creates a new query by specifying the query statement itself and the language in which the query is stated. If the query statement is syntactically invalid, given the language specified, an InvalidQueryException is thrown. The language must be a string from among those returned by QueryManager.getSupportedQueryLanguages(); if it is not, then an InvalidQueryException is thrown.

Specified by:

createQuery in interface QueryManager

Returns:

A Query object.

Throws:

javax.jcr.query.InvalidQueryException - if statement is invalid or language is unsupported.

javax.jcr.RepositoryException - if another error occurs

getQuery

public Query getQuery(javax.jcr.Node node)
               throws javax.jcr.query.InvalidQueryException,
                      javax.jcr.RepositoryException

Description copied from interface: QueryManager

Description inherited from javax.jcr.query.QueryManager#getQuery(javax.jcr.Node)
Retrieves an existing persistent query. If node is not a valid persisted query (that is, a node of type nt:query), an InvalidQueryException is thrown.

Persistent queries are created by first using QueryManager.createQuery to create a Query object and then calling Query.save to persist the query to a location in the workspace.

Specified by:

getQuery in interface QueryManager

Parameters:

node - a persisted query (that is, a node of type nt:query).

Returns:

a Query object.

Throws:

javax.jcr.query.InvalidQueryException - If node is not a valid persisted query (that is, a node of type nt:query).

javax.jcr.RepositoryException - if another error occurs

getSupportedQueryLanguages

public String[] getSupportedQueryLanguages()
                                    throws javax.jcr.RepositoryException

Description copied from interface: QueryManager

Description inherited from javax.jcr.query.QueryManager#getSupportedQueryLanguages()
Returns an array of strings representing all query languages supported by this repository. In level 1 this set must include the string represented by the constant Query.XPATH. If SQL is supported it must additionally include the string represented by the constant Query.SQL. An implementation may also support other languages as well. See Query.

Specified by:

getSupportedQueryLanguages in interface QueryManager

Returns:

An string array.

Throws:

javax.jcr.RepositoryException - if an error occurs.
