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 LengthExpression 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 AbstractSingleEncapsulatedExpressionStateObject

  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 String getIdentifier()

  Returns the JPQL identifier of the expression represented by this AbstractSingleEncapsulatedExpressionStateObject.

  Specified by:

  getIdentifier in class AbstractEncapsulatedExpressionStateObject

  Returns:

  The JPQL identifier that is shown before the left parenthesis

• setExpression

  public void setExpression​(LengthExpression 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 LENGTH expression

• setStateObject

  public void setStateObject​(StateObject stateObject)
