Method Summary

Modifier and TypeMethod and Description
public void
addBeanContextMembershipListener(BeanContextMembershipListener
the BeanContextMembershipListener to be added
bcml)
References Deprecated BeanContextMembershipListener is deprecated or references (maybe indirectly) at least one deprecated element.

Adds the specified BeanContextMembershipListener to receive BeanContextMembershipEvents from this BeanContext whenever it adds or removes a child Component(s).

public URL

Returns:

a URL for the named resource for the specified child
getResource(String
the resource name
name, BeanContextChild
the specified child
bcc)
References Deprecated BeanContextChild is deprecated or references (maybe indirectly) at least one deprecated element.

Analogous to java.lang.ClassLoader.getResource(), this method allows a BeanContext implementation to interpose behavior between the child Component and underlying ClassLoader.

public InputStream

Returns:

an InputStream for reading the resource, or null if the resource could not be found.
getResourceAsStream(String
the resource name
name, BeanContextChild
the specified child
bcc)
References Deprecated BeanContextChild is deprecated or references (maybe indirectly) at least one deprecated element.

Analogous to java.lang.ClassLoader.getResourceAsStream(), this method allows a BeanContext implementation to interpose behavior between the child Component and underlying ClassLoader.

public Object

Returns:

a javaBean named as a child of this BeanContext
instantiateChild(String
The name of the JavaBean to instantiate as a child of this BeanContext
beanName)

Instantiate the javaBean named as a child of this BeanContext.

public void
removeBeanContextMembershipListener(BeanContextMembershipListener
the BeanContextMembershipListener to be removed
bcml)
References Deprecated BeanContextMembershipListener is deprecated or references (maybe indirectly) at least one deprecated element.

Removes the specified BeanContextMembershipListener so that it no longer receives BeanContextMembershipEvents when the child Component(s) are added or removed.

instantiateChildback to summary
public Object instantiateChild(String beanName) throws IOException, ClassNotFoundException
