Method Detail

newFcMembrane

protected Component newFcMembrane(Type type,
                                  Object controllerDesc,
                                  Object contentDesc,
                                  Object content)
                           throws InstantiationException

Create a new control membrane.

Specified by:

newFcMembrane in class AbstractGenericFactoryImpl

Parameters:

type - the type of the component associated to this membrane

controllerDesc - the controller description of this membrane (typically a String such as "primitive" or any of the other registered membrane identifier)

contentDesc - the content description of the component associated to this membrane (e.g. the fully qualified name of the class implementing a primitive component)

content - the instance implementing the component associated to this membrane

Returns:

the fcinterface for the component interface exported by the given control membrane

Throws:

InstantiationException

bindFcMembrane

protected Component bindFcMembrane(Type type,
                                   Object contentDesc,
                                   Object content,
                                   Component membrane)
                            throws InstantiationException

Bind a control membrane to the component defined by the given type, content description and content.

Specified by:

bindFcMembrane in class AbstractGenericFactoryImpl

Parameters:

type - the type of the component associated to this membrane

contentDesc - the content description of the component associated to this membrane (e.g. the fully qualified name of the class implementing a primitive component)

content - the instance implementing the component associated to this membrane

membrane - the control membrane

Returns:

the fcinterface for the component interface exported by the given control membrane

Throws:

InstantiationException

loadFcContentClass

protected Class loadFcContentClass(Object controllerDesc,
                                   String contentDescStr)
                            throws InstantiationException

Load the specified content class. First, try to load the class from the classpath. If that fails, assume that the specified contentDesc corresponds to an alias defined in the julia.cfg configuration file. This is case for control component where the content class is dynamically generated by the ASM mixin class generator.

Overrides:

loadFcContentClass in class AbstractGenericFactoryImpl

Parameters:

controllerDesc - the controller descriptor of the component for which the content class is requested

contentDescStr - the content descriptor. May be a fully-qualified class name or the stringified representation of a Tree to be loaded by a Julia Loader.

Throws:

InstantiationException
