public ComponentProvider()

Method Detail

isApplicable

public abstract boolean isApplicable(java.lang.Class<?> c)

Checks whether this component provider is able to provide an instance of given Class.

Parameters:

c - Class to be checked.

Returns:

true iff this ComponentProvider is able to create an instance of the given Class.

create

public abstract <T> java.lang.Object create(java.lang.Class<T> c)

Create new instance.

Type Parameters:

T - type of the created object.

Parameters:

c - Class to be created.

Returns:

instance, iff found, null otherwise.

getInvocableMethod

public java.lang.reflect.Method getInvocableMethod(java.lang.reflect.Method method)

Get the method which should be invoked instead provided one.

Useful mainly for EJB container support, where methods from endpoint class cannot be invoked directly - Tyrus needs to use method declared on remote interface.

Default implementation returns method provided as parameter.

Parameters:

method - method from endpoint class.

Returns:

method which should be invoked.

destroy

public abstract boolean destroy(java.lang.Object o)

Destroys the given managed instance.

Parameters:

o - instance to be destroyed.

Returns:

true iff the instance was coupled to this ComponentProvider, false otherwise.
