Method Summary

Modifier and Type	Method	Description
void	delete(LogicalDatastoreType store, YangInstanceIdentifier path)	Removes a piece of data from specified path.
void	merge(LogicalDatastoreType store, YangInstanceIdentifier path, NormalizedNode<?,?> data)	Merges a piece of data with the existing data at a specified path.
void	put(LogicalDatastoreType store, YangInstanceIdentifier path, NormalizedNode<?,?> data)	Stores a piece of data at the specified path.

Method Detail

put

void put(LogicalDatastoreType store,
         YangInstanceIdentifier path,
         NormalizedNode<?,?> data)

Stores a piece of data at the specified path. This acts as an add / replace operation, which is to say that whole subtree will be replaced by the specified data.

If you need to make sure that a parent object exists but you do not want modify its pre-existing state by using put, consider using merge(org.opendaylight.mdsal.common.api.LogicalDatastoreType, org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier, org.opendaylight.yangtools.yang.data.api.schema.NormalizedNode<?, ?>) instead.

Parameters:

store - the logical data store which should be modified

path - the data object path

data - the data object to be written to the specified path

Throws:

IllegalStateException - if the transaction has already been submitted

merge

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

Merges a piece of data with the existing data at a specified path. Any pre-existing data which is not explicitly overwritten will be preserved. This means that if you store a container, its child lists will be merged.

If you require an explicit replace operation, use put(org.opendaylight.mdsal.common.api.LogicalDatastoreType, org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier, org.opendaylight.yangtools.yang.data.api.schema.NormalizedNode<?, ?>) instead.

Parameters:

store - the logical data store which should be modified

path - the data object path

data - the data object to be merged to the specified path

Throws:

IllegalStateException - if the transaction has already been submitted

delete

void delete(LogicalDatastoreType store,
            YangInstanceIdentifier path)

Removes a piece of data from specified path. This operation does not fail if the specified path does not exist.

Parameters:

store - Logical data store which should be modified

path - Data object path

Throws:

IllegalStateException - if the transaction was committed or canceled.
