Constructor Detail

ArithmeticExpressionStateObject

protected ArithmeticExpressionStateObject(StateObject parent)

Creates a new ArithmeticExpressionStateObject.

Parameters:

parent - The parent of this state object, which cannot be null

Throws:

java.lang.NullPointerException - The given parent cannot be null

ArithmeticExpressionStateObject

protected ArithmeticExpressionStateObject(StateObject parent,
                                          StateObject leftStateObject,
                                          StateObject rightStateObject)

Creates a new ArithmeticExpressionStateObject.

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

ArithmeticExpressionStateObject

protected ArithmeticExpressionStateObject(StateObject parent,
                                          java.lang.String leftJpqlFragment,
                                          java.lang.String rightJpqlFragment)

Creates a new ArithmeticExpressionStateObject.

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 ArithmeticExpression 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)

getLeftQueryBNFId

protected java.lang.String getLeftQueryBNFId()

Returns the unique identifier of the BNF that will be used to parse a JPQL fragment as the left side of the expression.

Specified by:

getLeftQueryBNFId in class CompoundExpressionStateObject

Returns:

The query BNF ID for the left side of the expression

getRightQueryBNFId

protected java.lang.String getRightQueryBNFId()

Returns the unique identifier of the BNF that will be used to parse a JPQL fragment as the right side of the expression.

Specified by:

getRightQueryBNFId in class CompoundExpressionStateObject

Returns:

The query BNF ID for the right side of the expression
