Class SQLDescriptor

java.lang.Object
  com.sun.mdm.index.query.SQLDescriptor

All Implemented Interfaces:

java.io.Serializable

class SQLDescriptor

extends java.lang.Object

implements java.io.Serializable

This class contains data that is used to issue a SQL query and to assemble composite object tree. So a QueryParser after parsing the QueryObject, converts it into SQLDescriptors (array of SQLDescriptors, if it requires multiple SQL queries) and pass SQLDescritor back to QueryManager. So the data contained in this class is: SQL statements. key indices of all the objects in the SQL statement. Attribute indices of the objects that will be selected from this query. Parent key indices of an object.
