Constructor Detail

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

getMinBlobSize

public long getMinBlobSize()

Returns the minimum blob size

Returns:

the minimum blob size

See Also:

for details.

setMinBlobSize

public void setMinBlobSize(long minBlobSize)

Sets the minimum blob size. Binary values that are shorted than this given size will be inlined in the serialization stream, binary value that are longer, will be stored in the blob store. default is 4k.

Parameters:

minBlobSize - the minimum blob size.

getBlobStore

public BLOBStore getBlobStore()

Returns the blob store that is associated with this binding.

Returns:

the blob store

readBundle

public NodePropBundle readBundle(InputStream 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.

writeBundle

public void writeBundle(OutputStream 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.
