Method Summary

Modifier and TypeMethod and Description
public void
accept(StateObjectVisitor
The visitor to visit this object
visitor)

Implements org.eclipse.persistence.jpa.jpql.tools.model.query.StateObject.accept.

Visits this StateObject by the given visitor.
public MultiplicationExpression
getExpression()

Overrides org.eclipse.persistence.jpa.jpql.tools.model.query.ArithmeticExpressionStateObject.getExpression.

Implements org.eclipse.persistence.jpa.jpql.tools.model.query.StateObject.getExpression.

Returns the actual parsed object if this StateObject representation of the JPQL query was created by parsing an existing JPQL query.
public String
getIdentifier()

Implements abstract org.eclipse.persistence.jpa.jpql.tools.model.query.CompoundExpressionStateObject.getIdentifier.

Returns the identifier joining the two StateObjects.
public void
setExpression(MultiplicationExpression
The parsed object representing a subtraction expression
expression)

Keeps a reference of the parsed object object, which should only be done when this object is instantiated during the conversion of a parsed JPQL query into StateObjects.
