Method Detail

• getValueReference

  public static ValueReference getValueReference(ELContext context,
                                 ValueExpression valueExpression)

  Gets the ValueReference from a ValueExpression, without any checks whether the property is actually a property or if it isn't a "MethodSuffix". The property is stored as it appears in the expression, and may thus not actually exists. It's up to the caller how to interpret this.

  This is also a workaround for the fact that a ValueReference can't be obtained from a TagValueExpression in JSF 2.x (since it doesn't implement getValueReference and its super class just returns null).

  Parameters:

  context - the context of this evaluation

  valueExpression - the value expression being evaluated

  Returns:

  a ValueReference holding the final base and property where the value expression evaluated to.

• getMethodReference

  public static MethodReference getMethodReference(ELContext context,
                                   ValueExpression valueExpression)

  Gets a MethodReference from a ValueExpression. This assumes that this expression references a method.

  Note that the method reference contains a method with the name the expression refers to. Overloads are not supported.

  Parameters:

  context - the context of this evaluation

  valueExpression - the value expression being evaluated

  Returns:

  a MethodReference holding the final base and Method where the value expression evaluated to.

• findMethod

  public static Method findMethod(Object base,
                  String methodName)

  Finds a method based on the method name only. Does not support overloaded methods.

  Parameters:

  base - the object in which the method is to be found

  methodName - name of the method to be found

  Returns:

  a method if one is found, null otherwise
