Constructor Detail

DefaultLazyLoader

public DefaultLazyLoader(org.zkoss.zk.ui.Component container,
                         java.util.List<org.zkoss.zk.ui.Component> components)

Creates a new DefaultLazyLoader instance with the specified lazy load parent and child components.

Parameters:

container - component to which the lazy loaded child components will be attached

components - components which should be lazy loaded

Method Detail

loadComponents

public void loadComponents()

Loads the "lazy loaded" child components (see LazyLoader.setLazyLoadChildren(List)) bit-by-bit i.e. attaches the components to the lazy load parent (see LazyLoader.setLazyLoadParent(Component)) in multiple event cycles.

The default implementation loads components one-by-one using multiple echo events between server and client.

Specified by:

loadComponents in interface LazyLoader

setLazyLoadChildren

public void setLazyLoadChildren(java.util.List<org.zkoss.zk.ui.Component> children)

Description copied from interface: LazyLoader

Sets the components which should be lazy loaded.

When the LazyLoader.loadComponents() method is called, the components in the specified list children will be attached to the lazy load parent (see LazyLoader.setLazyLoadParent(Component)).

Specified by:

setLazyLoadChildren in interface LazyLoader

Parameters:

children - components which should be lazy loaded

setLazyLoadParent

public void setLazyLoadParent(org.zkoss.zk.ui.Component parent)

Description copied from interface: LazyLoader

Sets the parent component to be used for the lazy loaded child components.

Specified by:

setLazyLoadParent in interface LazyLoader

Parameters:

parent - component to which the lazy loaded child components will be attached
