public interface BeanContext extends BeanContextChild, Collection, DesignMode, Visibility
The BeanContext acts a logical hierarchical container for JavaBeans.
Modifier and Type | Field | Description |
---|---|---|
static final Object |
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 | Description |
---|---|---|
void |
addBeanContextMembershipListener |
Adds the specified BeanContextMembershipListener to receive BeanContextMembershipEvents from this BeanContext whenever it adds or removes a child Component (s). |
URL |
getResource |
Analogous to java.lang.ClassLoader.getResource() , this method allows a BeanContext implementation to interpose behavior between the child Component and underlying ClassLoader . |
InputStream |
getResourceAsStream |
Analogous to java.lang.ClassLoader.getResourceAsStream() , this method allows a BeanContext implementation to interpose behavior between the child Component and underlying ClassLoader . |
Object |
instantiateChild |
Instantiate the javaBean named as a child of this BeanContext . |
void |
removeBeanContextMembershipListener |
Removes the specified BeanContextMembershipListener so that it no longer receives BeanContextMembershipEvent s when the child Component (s) are added or removed. |
