All Implemented Interfaces:

Serializable, Cloneable, Call

public class JPQLCall
extends Object

public String getCallString()

INTERNAL: Return the string for the call

getEjbqlString

public String getEjbqlString()

INTERNAL: Return the EJBQL string for this call

getQuery

public DatabaseQuery getQuery()

Back reference to query, unfortunately required for events.

getLogString

INTERNAL: Return the SQL string for this call. Always return null since this is an EJBQL call

Specified by:

getLogString in interface Call

getSQLString

public String getSQLString()
