Constructor Detail

StaticFunction

public StaticFunction(Class p_class,
                      String p_name)

Creates a function that targets the static methods of the given class which match the given name. See StaticFunction(Class,String,Object[]) for more details.

StaticFunction

public StaticFunction(Class p_class,
                      String p_name,
                      Object[] p_parameters)

Creates a function that targets the static methods of the given class which match the given name, with the supplied parameters.

Parameters:

p_class - the class of the target.

p_name - the name to match, either exactly or by interpreting the name as a property and matching on the corresponding getter and setter methods.

p_parameters - the parameters to be supplied to the method.

Throws:

FunctionException - thrown if no methods of the target class match the given name.

Method Detail

isObjectRequired

public boolean isObjectRequired()

Returns false since an object is not required to invoke the method.

Specified by:

isObjectRequired in class Function

Returns:

false.

newInstance

protected Function newInstance(Class p_class,
                               Object[] p_parameters)

Creates a new StaticFunction object using the specified target class and parameters.

Specified by:

newInstance in class Function

Parameters:

p_class - the class of the target.

p_parameters - the supplied parameters.

Returns:

a new StaticFunction object of the target class, containing the supplied parameters.

object

public Function object(Object p_object)
                throws FunctionException

Throws a FunctionException, since no object is required to invoke a static method.

Specified by:

object in class Function

Throws:

FunctionException - always thrown since invoking this method is not applicable to instances of the StaticFunction class.
