Interface JAXXContext

All Known Subinterfaces:

JAXXObject

public interface JAXXContext

The JAXXContext contract defines a generic context. A context contains two king of entries :

Unamed entry

a such entry maps filter only on the clas of the object of the entry. To add a unamed entry, use setContextValue(Object) and getContextValue(Class) to reteave a such entry.

named entry

a such entry filter on class of the object and on the name of the entry. To add a named entry, use setContextValue(Object, String) and getContextValue(Class, String) to reteave a such entry.

Method Detail

setContextValue

<T> void setContextValue(T o)

Push in the context a new unamed entry. If a previous entry exists in context (unamed and same class), it will be removed.

Type Parameters:

T - type of data to set in context

Parameters:

o - the value to push in context

setContextValue

<T> void setContextValue(T o,
                         String name)

* Push in the context a new amed entry. If a previous entry exists in context (same name and class), it will be removed.

Type Parameters:

T - type of data to set in context

Parameters:

o - the value to push in context

name - the name of the new entry

removeContextValue

<T> void removeContextValue(Class<T> klazz)

Remove from context the value with the given klazz as an unamed entry

Type Parameters:

T - type of data to remove from context

Parameters:

klazz - the klazz entry

removeContextValue

<T> void removeContextValue(Class<T> klazz,
                            String name)

Remove from context the value with the given klazz as an unamed (if name is null) or named entry

Type Parameters:

T - type of data to remove from context

Parameters:

klazz - the klazz entry

name - extra name of the entry

getContextValue

<T> T getContextValue(Class<T> clazz)

Seek for a unamed entry in the context This is an exemple to call a method in JAXX : <JButton onActionPerformed='{getContextValue(Action.class).method(args[])}'/>

Type Parameters:

T - type of data to obtain from context

Parameters:

clazz - the class of unamed entry to seek in context

Returns:

the value of the unamed entry for the given class, or null if no such entry.

getContextValue

<T> T getContextValue(Class<T> clazz,
                      String name)

Seek for a named entry in the context

Type Parameters:

T - type of data to obtain from context

Parameters:

clazz - the class of named entry to seek in context

name - the name of the entry to seek in context

Returns:

the value of the named entry for the given class, or null if no such entry.
