Class CodeRootContainer<D extends CodeRootContainerDelegate>

java.lang.Object

org.praxislive.code.CodeComponent<D>

org.praxislive.code.CodeRoot<D>

org.praxislive.code.CodeRootContainer<D>

Type Parameters:

D - wrapped delegate type

All Implemented Interfaces:

Component, Container, Lookup.Provider, Root

public class CodeRootContainer<D extends CodeRootContainerDelegate>
extends CodeRoot<D>
implements Container

A Root container instance that is rewritable at runtime. The CodeRootContainer itself remains constant, but passes most responsibility to a CodeRootContainer.Context wrapping a CodeRootContainerDelegate (user code). This component handles switching from one context to the next. A CodeRoot cannot be created directly - see CodeFactory.

Method Detail

children

public Stream<String> children()

Description copied from interface: Container

Get a Stream of the child IDs that this container makes publicly visible. Containers may have hidden children that can be returned from Container.getChild(java.lang.String) but are not listed here. All IDs returned should correspond to valid components, and (if provided) match the implementation of ContainerProtocol.

A Stream is returned allowing flexibility in implementation.

Specified by:

children in interface Container

Returns:

stream of public child IDs

getAddress

public ComponentAddress getAddress(Component child)

Description copied from interface: Container

Get the address for the provided child component, or null if the component is not a child of this container.

Specified by:

getAddress in interface Container

Parameters:

child - component

Returns:

address, or null of component is not a child of this container.

getChild

public Component getChild(String id)

Description copied from interface: Container

Get child component with specific ID.

Specified by:

getChild in interface Container

Returns:

Component, or null if no component with that ID exists.

getLookup

public Lookup getLookup()

Description copied from interface: Lookup.Provider

Get the Lookup from this Provider.

Specified by:

getLookup in interface Lookup.Provider

Overrides:

getLookup in class CodeRoot<D extends CodeRootContainerDelegate>

Returns:

lookup

hierarchyChanged

public void hierarchyChanged()

Description copied from interface: Component

Notify the component that a change has happened in its component hierarchy. For example its direct parent or an ancestor has changed. This method will be called after parentNotify() if the result of an immediate parent change.

Specified by:

hierarchyChanged in interface Component

Overrides:

hierarchyChanged in class CodeRoot<D extends CodeRootContainerDelegate>
