call

@CheckForNull
public static java.lang.Object call(ParameterizedExpression expression,
                                                  java.lang.Object... arguments)
                                           throws java.lang.Exception

Simplified ParametrizedExpression call. Intended for easier usage from scripts. ValueContext is null.

Parameters:

expression - expression to call. If not ParametrizedExpression result will be null

arguments - arguments for the expression

Returns:

expression result

Throws:

java.lang.Exception - various exceptions, mostly from java.lang.reflect.Method#invoke(java.lang.Object, java.lang.Object...)

call

@CheckForNull
public static java.lang.Object call(ParameterizedExpression parameterizedExpression,
                                                  @CheckForNull
                                                  java.util.List<?> arguments,

                                           throws java.lang.Exception

Call parameterizedExpression and returns value.

Parameters:

parameterizedExpression - expression which should be called

arguments - arguments for the expression. If arguments do ot match, then exception will be thrown

valueContext - value context for the evaluated value. Usually null

Returns:

value of the expression call

Throws:

java.lang.Exception - various exceptions, mostly from java.lang.reflect.Method#invoke(java.lang.Object, java.lang.Object...)

Parameters:

behavior - behavior which represents an expression.

Returns:

parameterized expression.
