runNamedQuery

public java.lang.Object runNamedQuery(org.python.core.PyObject[] values,
                                      java.lang.String[] keywords)
                               throws java.lang.Exception

This invokes the gateway rpc, which only uses the saved query version. Named queries are "safe", so does not need the ClientProtection annotation.

Returns:

Results of the query. May be null or empty if the query failed or returned no results.

Throws:

GatewayException - If path is invalid or query can't be run.

java.lang.Exception

clearNamedQueryCache

public void clearNamedQueryCache(java.lang.String path)
                          throws GatewayException

Clears the cache of the named query specified by the path parameter.

Parameters:

path - The Path to the named query we want to clear the cache of in the current project. Will use published version. May not be null.

Throws:

GatewayException - if the path is malformed.

clearAllNamedQueryCaches

public void clearAllNamedQueryCaches()
                              throws GatewayException

Clears all named query caches for the current project.

Throws:

GatewayException - if there is an error clearing all the named query caches.
