public interface BeanContext
extends BeanContextChild, Collection, DesignMode, Visibility

The BeanContext acts a logical hierarchical container for JavaBeans.

1.2

Field Summary
static 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.

Method Summary
 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.

Field Detail

globalHierarchyLock

public 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.
Method Detail

instantiateChild

public Object instantiateChild(String beanName)
                        throws IOException,
                               ClassNotFoundException
Instantiate the javaBean named as a child of this BeanContext. The implementation of the JavaBean is derived from the value of the beanName parameter, and is defined by the java.beans.Beans.instantiate() method.
Parameters:
beanName - The name of the JavaBean to instantiate as a child of this BeanContext
Throws:
IOException -  
ClassNotFoundException - if the class identified by the beanName parameter is not found

getResourceAsStream

public InputStream getResourceAsStream(String name,
                                       BeanContextChild bcc)
                                throws IllegalArgumentException
Analagous to java.lang.ClassLoader.getResourceAsStream(), this method allows a BeanContext implementation to interpose behavior between the child Component and underlying ClassLoader.
Parameters:
name - the resource name
bcc - the specified child
Returns:
an InputStream for reading the resource, or null if the resource could not be found.
Throws:
IllegalArgumentException - if the resource is not valid

getResource

public URL getResource(String name,
                       BeanContextChild bcc)
                throws IllegalArgumentException
Analagous to java.lang.ClassLoader.getResource(), this method allows a BeanContext implementation to interpose behavior between the child Component and underlying ClassLoader.
Parameters:
name - the resource name
bcc - the specified child
Returns:
a URL for the named resource for the specified child
Throws:
IllegalArgumentException - if the resource is not valid

addBeanContextMembershipListener

public void addBeanContextMembershipListener(BeanContextMembershipListener bcml)
Adds the specified BeanContextMembershipListener to receive BeanContextMembershipEvents from this BeanContext whenever it adds or removes a child Component(s).
Parameters:
bcml - the BeanContextMembershipListener to be added

removeBeanContextMembershipListener

public void removeBeanContextMembershipListener(BeanContextMembershipListener bcml)
Removes the specified BeanContextMembershipListener so that it no longer receives BeanContextMembershipEvents when the child Component(s) are added or removed.
Parameters:
bcml - the BeanContextMembershipListener to be removed
