  org.deckfour.xes.model.buffered.XAbstractAttributeMapBufferedImpl

All Implemented Interfaces:

Cloneable, Map<String,XAttribute>, XAttributeMap

Direct Known Subclasses:

XAttributeMapBufferedImpl

public abstract class XAbstractAttributeMapBufferedImpl
extends Object
implements XAttributeMap

NikeFS2 virtual file system storage-based implementation for the XAttributeMap interface. Makes it possible to store maps of attributes on disk memory, transparent to the user and the using application.

Constructor Detail

XAbstractAttributeMapBufferedImpl

protected XAbstractAttributeMapBufferedImpl(XAttributeMapSerializer serializer)

Creates a new attribute map.

Parameters:

serializer - The serializer used to serialize this attribute map.

XAbstractAttributeMapBufferedImpl

protected XAbstractAttributeMapBufferedImpl(NikeFS2StorageProvider provider,
                                            XAttributeMapSerializer serializer)

Creates a new attribute map.

Parameters:

provider - Storage provider to use for serialization.

serializer - The serializer used to serialize this attribute map.

Method Detail

deserialize

protected XAttributeMap deserialize()
                             throws IOException

Retrieves a quick-access representation of this attribute map for actual usage. De-buffers the attribute map and creates an in-memory representation which should be discarded after use to free memory.

Returns:

In-memory copy of this attribute map.

Throws:

IOException

serialize

protected void serialize(XAttributeMap map)
                  throws IOException

Serializes the given attribute map to a disk-buffered representation.

Parameters:

map - Attribute map to be serialized.

Throws:

IOException
