globalHierarchyLock
This global lock is used by both
BeanContext
and BeanContextServices implementors
to serialize changes in a BeanContext
hierarchy and any service requests etc. |
PROPERTYNAME| Modifier and Type | Method and Description |
|---|---|
void |
addBeanContextMembershipListener(BeanContextMembershipListener bcml)
Adds the specified
BeanContextMembershipListener
to receive BeanContextMembershipEvents from
this BeanContext whenever it adds
or removes a child Component(s). |
URL |
getResource(String name,
BeanContextChild bcc)
Analagous to
java.lang.ClassLoader.getResource(), this
method allows a BeanContext implementation to interpose
behavior between the child Component
and underlying ClassLoader. |
InputStream |
getResourceAsStream(String name,
BeanContextChild bcc)
Analagous to
java.lang.ClassLoader.getResourceAsStream(),
this method allows a BeanContext implementation
to interpose behavior between the child Component
and underlying ClassLoader. |
Object |
instantiateChild(String beanName)
Instantiate the javaBean named as a
child of this
BeanContext. |
void |
removeBeanContextMembershipListener(BeanContextMembershipListener bcml)
Removes the specified
BeanContextMembershipListener
so that it no longer receives BeanContextMembershipEvents
when the child Component(s) are added or removed. |
