Constructor Detail

SubtractionExpressionStateObject

public SubtractionExpressionStateObject(StateObject parent)
Creates a new SubtractionExpressionStateObject.

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

SubtractionExpressionStateObject

public SubtractionExpressionStateObject(StateObject parent,
                                        StateObject leftStateObject,
                                        StateObject rightStateObject)
Creates a new SubtractionExpressionStateObject.

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

SubtractionExpressionStateObject

public SubtractionExpressionStateObject(StateObject parent,
                                        java.lang.String leftJpqlFragment,
                                        java.lang.String rightJpqlFragment)
Creates a new SubtractionExpressionStateObject.

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

accept

public void accept(StateObjectVisitor visitor)
Visits this StateObject by the given visitor.

Parameters:
visitor - The visitor to visit this object

getExpression

public SubtractionExpression 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 ArithmeticExpressionStateObject
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)

getIdentifier

public java.lang.String getIdentifier()
Returns the identifier joining the two StateObjects.

Specified by:
getIdentifier in class CompoundExpressionStateObject
Returns:
The JPQL identifier join two expressions

setExpression

public void setExpression(SubtractionExpression 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.

Parameters:
expression - The parsed object representing a subtraction expression
