Class SynchronizedDataTreeModification

java.lang.Object

org.opendaylight.yangtools.yang.data.api.schema.tree.SynchronizedDataTreeModification

All Implemented Interfaces:

DataTreeModification, DataTreeSnapshot

public final class SynchronizedDataTreeModification
extends Object
implements DataTreeModification

A DataTreeModification implementation which delegates all calls to another instance, making sure no method is being invoked from multiple threads concurrently.

Method Summary

Modifier and Type	Method and Description
void	applyToCursor(DataTreeModificationCursor cursor) Apply the contents of this modification to a cursor.
static DataTreeModification	create(DataTreeModification delegate)
void	delete(YangInstanceIdentifier path) Delete the node at specified path.
SchemaContext	getSchemaContext() Return the current SchemaContext, which is being used for operations.
void	merge(YangInstanceIdentifier path, NormalizedNode<?,?> data) Merge the specified data with the currently-present data at specified path.
DataTreeModification	newModification() Create a new data tree modification based on this snapshot, using the specified data application strategy.
Optional<NormalizedNode<?,?>>	readNode(YangInstanceIdentifier path) Read a particular node from the snapshot.
void	ready() Finish creation of a modification, making it ready for application to the data tree.
void	write(YangInstanceIdentifier path, NormalizedNode<?,?> data) Replace the data at specified path with supplied data.

Method Detail

create

public static DataTreeModification create(DataTreeModification delegate)

readNode

public Optional<NormalizedNode<?,?>> readNode(YangInstanceIdentifier path)

Description copied from interface: DataTreeSnapshot

Read a particular node from the snapshot.

Specified by:

readNode in interface DataTreeSnapshot

Parameters:

path - Path of the node

Returns:

Optional result encapsulating the presence and value of the node

newModification

public DataTreeModification newModification()

Description copied from interface: DataTreeSnapshot

Create a new data tree modification based on this snapshot, using the specified data application strategy.

Specified by:

newModification in interface DataTreeSnapshot

Returns:

A new data tree modification

delete

public void delete(YangInstanceIdentifier path)

Description copied from interface: DataTreeModification

Delete the node at specified path.

Specified by:

delete in interface DataTreeModification

Parameters:

path - Node path

merge

public void merge(YangInstanceIdentifier path,
                  NormalizedNode<?,?> data)

Description copied from interface: DataTreeModification

Merge the specified data with the currently-present data at specified path.

Specified by:

merge in interface DataTreeModification

Parameters:

path - Node path

data - Data to be merged

write

public void write(YangInstanceIdentifier path,
                  NormalizedNode<?,?> data)

Description copied from interface: DataTreeModification

Replace the data at specified path with supplied data.

Specified by:

write in interface DataTreeModification

Parameters:

path - Node path

data - New node data

ready

public void ready()

Description copied from interface: DataTreeModification

Finish creation of a modification, making it ready for application to the data tree. Any calls to this object's methods except DataTreeModification.applyToCursor(DataTreeModificationCursor) will result in undefined behavior, possibly with an IllegalStateException being thrown.

Specified by:

ready in interface DataTreeModification

applyToCursor

public void applyToCursor(@Nonnull
                          DataTreeModificationCursor cursor)

Description copied from interface: DataTreeModification

Apply the contents of this modification to a cursor. This can be used to replicate this modification onto another one. The cursor's position must match the root of this modification, otherwise performing this operation will result in undefined behavior.

Specified by:

applyToCursor in interface DataTreeModification

Parameters:

cursor - cursor to which this modification

getSchemaContext

public SchemaContext getSchemaContext()

Description copied from interface: DataTreeSnapshot

Return the current SchemaContext, which is being used for operations.

Specified by:

getSchemaContext in interface DataTreeSnapshot

Returns:

Current schema context.
