Method Detail

create

public abstract FilterContainerImpl create(Filter f,
                                           ESPK circuitPK)
                                    throws java.lang.InstantiationException,
                                           java.lang.IllegalAccessException,
                                           java.lang.ClassNotFoundException

Implemented by subclasses to perform the factory operation.

Parameters:

f - Filter to wrap

circuitPK - The PK of the filter's owner Circuit

Returns:

A new FilterContainer implementing specific functionality required by the Circuit's owner.

Throws:

java.lang.InstantiationException - If the Filter's class cannot be instantiated.

java.lang.IllegalAccessException - If there's a security issue when instantiating the Filter instance.

java.lang.ClassNotFoundException - If the implementation class is unkown to the Classloader.

forClass

protected FilterContainerImpl forClass(java.lang.Class<? extends FilterContainerImpl> klass,
                                       Filter filter,
                                       ESPK circuitPK)
                                throws java.lang.InstantiationException,
                                       java.lang.IllegalAccessException

Utility method for producing a filter container using the default constructor for a Class object.

Parameters:

klass - The class (should implement FilterContainerImpl

filter - The generic Filter object which holds common configuration for runtime and design time.

circuitPK - The PK of the filter's owner Circuit

Returns:

A new FilterContainer implementing specific functionality

Throws:

java.lang.InstantiationException - If the Filter's class cannot be instantiated.

java.lang.IllegalAccessException - If there's a security issue when instantiating the Filter instance.
