Constructor Detail

LogicalExpressionStateObject

protected LogicalExpressionStateObject(StateObject parent)
Creates a new LogicalExpressionStateObject.

Parameters:
parent - The parent of this state object, which cannot be null
Throws:
java.lang.NullPointerException - The given parent cannot be null

LogicalExpressionStateObject

protected LogicalExpressionStateObject(StateObject parent,
                                       StateObject leftStateObject,
                                       StateObject rightStateObject)
Creates a new LogicalExpressionStateObject.

Parameters:
parent - The parent of this state object, which cannot be null
leftStateObject - The StateObject representing the left expression
rightStateObject - The StateObject representing the right expression
Throws:
java.lang.NullPointerException - The given parent cannot be null

LogicalExpressionStateObject

protected LogicalExpressionStateObject(StateObject parent,
                                       java.lang.String leftJpqlFragment,
                                       java.lang.String rightJpqlFragment)
Creates a new LogicalExpressionStateObject.

Parameters:
parent - The parent of this state object, which cannot be null
leftJpqlFragment - The string representation of the left expression to parse and to convert into a StateObject
rightJpqlFragment - The string representation of the right expression to parse and to convert into a StateObject
Throws:
java.lang.NullPointerException - The given parent cannot be null
Method Detail

getExpression

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

Specified by:
getExpression in interface StateObject
Overrides:
getExpression in class CompoundExpressionStateObject
Returns:
The parsed object when a JPQL query is parsed and converted into a StateObject or null when the JPQL query is manually created (i.e. not from a string)
