Method Summary

Modifier and Type	Method	Description
void	compactSubTree()	We clear up the rare case that there are two items with the same TreeItem.getName() (can happen if there is, e.g., a group that has the same name as a package), which would lead to trouble with tree display since the same id was used twice.
RegistryItem	getItem(com.composum.sling.core.BeanContext context, String path)
RegistryItem	getItem(String name)
protected RegistryItem	getItemInternal(com.composum.sling.core.BeanContext context, String path)
void	load(com.composum.sling.core.BeanContext context)	Loads all details of this node from the package(s) and makes sure all children (RegistryItem.getItems()) are present, though not necessarily loaded.
void	loadForItems(com.composum.sling.core.BeanContext context)	Makes sure RegistryItem.getItems() are present, though not necessarily loaded.
void	toTree(com.google.gson.stream.JsonWriter writer, boolean children, boolean showRoot)

                            @Nonnull
                            String path)
                     throws IOException

Throws:

IOException

getItemInternal

@Nullable
protected RegistryItem getItemInternal(@Nonnull
                                       com.composum.sling.core.BeanContext context,

Throws:

IOException

load

public void load(@Nonnull
                 com.composum.sling.core.BeanContext context)
          throws IOException

Description copied from interface: RegistryItem

Loads all details of this node from the package(s) and makes sure all children (RegistryItem.getItems()) are present, though not necessarily loaded.

Throws:

IOException

loadForItems

public void loadForItems(@Nonnull
                         com.composum.sling.core.BeanContext context)
                  throws IOException

Description copied from interface: RegistryItem

Makes sure RegistryItem.getItems() are present, though not necessarily loaded. might or might not trigger a RegistryItem.load(BeanContext) if that's necessary for that. (Optimized version of RegistryItem.load(BeanContext) if we just need the RegistryItem.getItems()).

Throws:

IOException

toTree

public void toTree(@Nonnull
                   com.google.gson.stream.JsonWriter writer,
                   boolean children,
                   boolean showRoot)
            throws IOException

Specified by:

toTree in interface RegistryItem

Overrides:

toTree in class AbstractNode

Throws:

IOException

compactSubTree

public void compactSubTree()

Description copied from class: AbstractNode

We clear up the rare case that there are two items with the same TreeItem.getName() (can happen if there is, e.g., a group that has the same name as a package), which would lead to trouble with tree display since the same id was used twice. We take what's more specific (that is, not GroupNode) and add the children there.

Specified by:

compactSubTree in interface RegistryItem

Overrides:

compactSubTree in class AbstractNode

getItem

@Nullable
public RegistryItem getItem(@Nonnull
                            String name)

Specified by:

getItem in interface RegistryItem

Overrides:

getItem in class AbstractNode
