BundleBinding

public BundleBinding(ErrorHandling errorHandling,
                     BLOBStore blobStore,
                     StringIndex nsIndex,
                     StringIndex nameIndex,
                     DataStore dataStore)

Creates a new bundle binding

Parameters:

errorHandling - the error handling

blobStore - the blobstore for retrieving blobs

nsIndex - the namespace index

nameIndex - the name index

dataStore - the data store

Method Detail

readBundle

public NodePropBundle readBundle(DataInputStream in,
                                 NodeId id)
                          throws IOException

Deserializes a NodePropBundle from a data input stream.

Parameters:

in - the input stream

id - the node id for the new bundle

Returns:

the bundle

Throws:

IOException - if an I/O error occurs.

checkBundle

public boolean checkBundle(DataInputStream in)

Checks a NodePropBundle from a data input stream.

Parameters:

in - the input stream

Returns:

true if the data is valid; false otherwise.

writeBundle

public void writeBundle(DataOutputStream out,
                        NodePropBundle bundle)
                 throws IOException

Serializes a NodePropBundle to a data output stream

Parameters:

out - the output stream

bundle - the bundle to serialize

Throws:

IOException - if an I/O error occurs.

readPropertyEntry

public NodePropBundle.PropertyEntry readPropertyEntry(DataInputStream in,
                                                      PropertyId id)
                                               throws IOException

Deserializes a PropertyState from the data input stream.

Parameters:

in - the input stream

id - the property id for the new property entry

Returns:

the property entry

Throws:

IOException - if an I/O error occurs.

checkPropertyState

public boolean checkPropertyState(DataInputStream in)

Checks a PropertyState from the data input stream.

Parameters:

in - the input stream

Returns:

true if the data is valid; false otherwise.

writeState

public void writeState(DataOutputStream out,
                       NodePropBundle.PropertyEntry state)
                throws IOException

Serializes a PropertyState to the data output stream

Parameters:

out - the output stream

state - the property entry to store

Throws:

IOException - if an I/O error occurs.
