Package Summary Overview Summary

class:BeanContext [NONE]

All Superinterfaces:

BeanContextChild, Collection, DesignMode, Iterable, Visibility

All Known Subinterfaces:

BeanContextServices

All Known Implementing Classes:

BeanContextServicesSupport, BeanContextSupport
```
public interface BeanContext
extends BeanContextChild, Collection, DesignMode, Visibility
```
The BeanContext acts a logical hierarchical container for JavaBeans.

Since:

1.2

See Also:

Beans, BeanContextChild, BeanContextMembershipListener, PropertyChangeEvent, DesignMode, Visibility, Collection

field:globalHierarchyLock [NONE]

globalHierarchyLock
```
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:instantiateChild(java.lang.String) [NONE]

instantiateChild
```
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

Returns:

a javaBean named as a child of this BeanContext

Throws:

IOException - if an IO problem occurs

ClassNotFoundException - if the class identified by the beanName parameter is not found

method:getResourceAsStream(java.lang.String,java.beans.beancontext.BeanContextChild) [NONE]

getResourceAsStream
```
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

method:getResource(java.lang.String,java.beans.beancontext.BeanContextChild) [NONE]

getResource
```
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

method:addBeanContextMembershipListener(java.beans.beancontext.BeanContextMembershipListener) [NONE]

addBeanContextMembershipListener
```
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

method:removeBeanContextMembershipListener(java.beans.beancontext.BeanContextMembershipListener) [NONE]

removeBeanContextMembershipListener
```
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
