Interface ExternalizableUtilStrategy

All Known Implementing Classes:

DummyExternalizableUtil

public interface ExternalizableUtilStrategy

Interface that allows to provide different ways for implementing serialization of objects. The open source version of the server will just provide a dummy implementation that does nothing. The enterprise version will use Coherence as its underlying mechanism.

Method Detail

writeStringMap

void writeStringMap(DataOutput out,
                    Map<String,String> stringMap)
                    throws IOException

Writes a Map of String key and value pairs. This method handles the case when the Map is null.

Parameters:

out - the output stream.

stringMap - the Map of String key/value pairs.

Throws:

IOException - if an error occurs.

readStringMap

Map<String,String> readStringMap(DataInput in)
                                 throws IOException

Reads a Map of String key and value pairs. This method will return null if the Map written to the stream was null.

Parameters:

in - the input stream.

Returns:

a Map of String key/value pairs.

Throws:

IOException - if an error occurs.

writeLongIntMap

void writeLongIntMap(DataOutput out,
                     Map<Long,Integer> map)
                     throws IOException

Writes a Map of Long key and Integer value pairs. This method handles the case when the Map is null.

Parameters:

out - the output stream.

map - the Map of Long key/Integer value pairs.

Throws:

IOException - if an error occurs.

readLongIntMap

Map readLongIntMap(DataInput in)
                   throws IOException

Reads a Map of Long key and Integer value pairs. This method will return null if the Map written to the stream was null.

Parameters:

in - the input stream.

Returns:

a Map of Long key/Integer value pairs.

Throws:

IOException - if an error occurs.

writeStringList

void writeStringList(DataOutput out,
                     List stringList)
                     throws IOException

Writes a List of Strings. This method handles the case when the List is null.

Parameters:

out - the output stream.

stringList - the List of Strings.

Throws:

IOException - if an error occurs.

readStringList

List<String> readStringList(DataInput in)
                            throws IOException

Reads a List of Strings. This method will return null if the List written to the stream was null.

Parameters:

in - the input stream.

Returns:

a List of Strings.

Throws:

IOException - if an error occurs.

writeLongArray

void writeLongArray(DataOutput out,
                    long[] array)

array - the array of long values.

Throws:

IOException - if an error occurs.

readLongArray

long[] readLongArray(DataInput in)
                     throws IOException
