Method Detail

setURL

public final void setURL(java.net.URL url)

Description copied from class: Node

Sets the URL associated with this Node and recaches the Node in the NodeFactory with the new URL so that subsequent queries for the Node will return successfully.

Specified by:

setURL in interface Locatable

Overrides:

setURL in class Node

Parameters:

url - The URL to set.

See Also:

Locatable.setURL(URL)

copyTo

public abstract java.lang.Object copyTo(java.lang.Object target)

copyToImpl

protected final void copyToImpl(HashStructureNode copy)

getProperties

public final HashStructure getProperties()

Returns a cascading HashStructure that represents this project's persistent properties. "Cascading" means that the returned HashStructure actually encapsulates two HashStructures -- a user-private one and a team-level ("shared") one.

Property lookups on the cascading HashStructure will start in the user-private structure and, if the property value is not assigned there, fallback on the shared structure.

Property changes on the cascading HashStructure are only applied to the user-private structure. To make changes to the shared structure, use DataContainer.getSharedPropertiesOnly().

Specified by:

getProperties in interface PropertyStorage

Overrides:

getProperties in class DataContainer

Returns:

The HashStructure wrapped by this PropertyStorage.

getPropertiesForOverriding

public final HashStructure getPropertiesForOverriding()

getUserPropertiesOnly

public final HashStructure getUserPropertiesOnly()

Returns a HashStructure that contains only the user-private properties (no shared properties).

Overrides:

getUserPropertiesOnly in class DataContainer

openImpl

protected void openImpl()
                 throws java.io.IOException

Description copied from class: Node

Subclasses should override this method to customize the open() behavior. Node.open() invokes this only if the node is not open, under write lock. The Node implementation does nothing.

Overrides:

openImpl in class Node

Throws:

java.io.IOException - if an I/O error occurred while opening

closeImpl

protected void closeImpl()
                  throws java.io.IOException

Description copied from class: Node

Subclasses should override this method to customize the close() behavior. Node.close() invokes this only if the node is open, under write lock. The Node implementation does nothing.

Overrides:

closeImpl in class DataContainer

Throws:

java.io.IOException - if an I/O error occurred while closing

saveImpl

protected void saveImpl()
                 throws java.io.IOException

Description copied from class: Node

Subclasses should override this method to customize the save() behavior. Node.save() invokes this only if the node is dirty, under write lock. The Node implementation does nothing.

Overrides:

saveImpl in class DataContainer

Throws:

java.io.IOException - if an I/O error occurred while saving

saveUserProperties

public final void saveUserProperties()
                              throws java.io.IOException

Throws:

java.io.IOException

newObjectStore

protected final ObjectStore newObjectStore()

Overrides:

newObjectStore in class DataContainer

newHashStructureIO

protected HashStructureIO newHashStructureIO()

getNamespaceURI

protected java.lang.String getNamespaceURI()

getRootQName

protected java.lang.String getRootQName()

getObjectStoreTarget

protected final java.lang.Object getObjectStoreTarget()

Overrides:

getObjectStoreTarget in class DataContainer

isDefault

public boolean isDefault()

For HashStructureNode subtypes that keep default state in a separate Node instance, this method should return true if this Node is the default instance.

isUserPropertiesEnabled

protected boolean isUserPropertiesEnabled()

Returns:

true if this HashStructureNode instance should enable support for keeping a distinct set of user properties from shared properties. If this method returns false, the user properties and shared properties will be the same HashStructure. The default implementation of this method always returns false. A subclass has to opt into enabling user properties.

applyBatchChanges

public final void applyBatchChanges(java.lang.Runnable runnable)

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class DataContainer

equalsImpl

protected final boolean equalsImpl(HashStructureNode other)
