OpenJDK 1.22 · java.beans.beancontext.BeanContext

Modifier and Type	Field and Description
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 Summary

Modifier and Type	Method and Description
public void	addBeanContextMembershipListener(BeanContextMembershipListener the BeanContextMembershipListener to be added bcml) 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) 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) 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) Removes the specified `BeanContextMembershipListener` so that it no longer receives `BeanContextMembershipEvent`s when the child `Component`(s) are added or removed.

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

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

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

Parameters

name:String: the resource name
bcc:BeanContextChild: the specified child

Returns:URL

a URL for the named resource for the specified child

Exceptions

IllegalArgumentException:: if the resource is not valid

Parameters name:String the resource name bcc:BeanContextChild the specified child Returns:InputStream an `InputStream` for reading the resource, or `null` if the resource could not be found. Exceptions IllegalArgumentException: if the resource is not valid

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

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

Parameters

name:String: the resource name
bcc:BeanContextChild: the specified child

Returns:InputStream

an InputStream for reading the resource, or null if the resource could not be found.

Exceptions

IllegalArgumentException:: if the resource is not valid

instantiateChild back to summary

instantiateChild	back to summary
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:String The name of the JavaBean to instantiate as a child of this `BeanContext` Returns:Object a javaBean named as a child of this `BeanContext` Exceptions IOException: if an IO problem occurs ClassNotFoundException: if the class identified by the beanName parameter is not found

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:String: The name of the JavaBean to instantiate as a child of this BeanContext

Returns:Object

a javaBean named as a child of this BeanContext

Exceptions

IOException:: if an IO problem occurs
ClassNotFoundException:: if the class identified by the beanName parameter is not found

removeBeanContextMembershipListener back to summary

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

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:BeanContextMembershipListener: the BeanContextMembershipListener to be removed
