Interface java.beans.beancontext.BeanContext

public interface BeanContext

extends BeanContextChild, Collection

The BeanContext acts a logical heirarchical container for JavaBeans, providing a general services mechanism.

Since:

JDK1.2

LOCALE_PROPERTYNAME

the value of the propertyName field fired in a PropertyChangeEvent as a result of calling setLocale()

addBeanContextMembershipListener(BeanContextMembershipListener)

add a BeanContextMembershipListener

getResource(String, BeanContextChild)

getResourceAsStream(String, BeanContextChild)

getService(Class, BeanContextChild)

BeanContexts may choose to provide a wide variety of "services" to their children by delegating a particular behavior to another object.

hasService(Class)

instantiateChild(String)

Instantiate the javaBean named as a child of this BeanContext

removeBeanContextMembershipListener(BeanContextMembershipListener)

remove a BeanContextMembershipListener

public static final String LOCALE_PROPERTYNAME

the value of the propertyName field fired in a PropertyChangeEvent as a result of calling setLocale()

public abstract Object instantiateChild(String beanName) throws IOException, ClassNotFoundException

Instantiate the javaBean named as a child of this BeanContext

Parameters:

beanName - The name of the JavaBean to instantiate as a child of this BeanContext

public abstract Object getService(Class serviceClass,
                                  BeanContextChild bcc)

BeanContexts may choose to provide a wide variety of "services" to their children by delegating a particular behavior to another object. These services would be realized in the form of references to instances of either Java classes or interfaces.

A BeanContext may delegate such requests to their own nesting contexts to be satisfied.

Returns:

a reference to this context's service as requested or null

public abstract boolean hasService(Class serviceClass)

Returns:

if the BeanContext supports this delegate type.

public abstract InputStream getResourceAsStream(String name,
                                                BeanContextChild bcc) throws IllegalArgumentException

Returns:

an InputStream to the named resource for the specified child

public abstract URL getResource(String name,
                                BeanContextChild bcc) throws IllegalArgumentException

Returns:

a URL for the named resource for the specified child

public abstract void addBeanContextMembershipListener(BeanContextMembershipListener bcml)

add a BeanContextMembershipListener

public abstract void removeBeanContextMembershipListener(BeanContextMembershipListener bcml)

remove a BeanContextMembershipListener
