Class QueryResultSet.ItemStruct

java.lang.Object
  jsdai.lang.QueryResultSet.ItemStruct

All Implemented Interfaces:

java.io.Serializable, jsdai.query.SerializableRef

Enclosing class:

QueryResultSet

public static class QueryResultSet.ItemStruct

extends java.lang.Object

implements jsdai.query.SerializableRef

This class is a structure to store query result item value in an efficient way. It implements interface SerializableRef therefore objects of class can be passed to getXxxByRef methods directly as long as they contain reference to JSDAI object of interest.

Since:

3.6.0
