Method Summary

static boolean	canRead(java.nio.ByteBuffer buffer, boolean optimizePositive) Reads true if the buffer contains enough data to read an int that was written with put(ByteBuffer, int, boolean).
static int	get(java.nio.ByteBuffer buffer, boolean optimizePositive) Reads an int from the buffer that was written with put(ByteBuffer, int, boolean).
static int	length(int value, boolean optimizePositive) Reads true if the buffer contains enough data to read an int that was written with put(ByteBuffer, int, boolean).
static int	put(java.nio.ByteBuffer buffer, int value, boolean optimizePositive) Writes the specified int to the buffer using 1 to 5 bytes, depending on the size of the number.
java.lang.Integer	readObjectData(java.nio.ByteBuffer buffer, java.lang.Class type) Reads an object from the buffer.
void	writeObjectData(java.nio.ByteBuffer buffer, java.lang.Object object) Writes the object to the buffer.

IntSerializer

public IntSerializer()

IntSerializer

public IntSerializer(boolean optimizePositive)

Parameters:

optimizePositive - Determines how many bytes are written to serialize various ranges of integers:

Bytes	true	false
1	0 <= value <= 127	-64 <= value <= 63
2	128 <= value <= 16383	-8192 <= value <= 8191
3	16384 <= value <= 2097151	-1048576 <= value <= 1048575
4	2097152 <= value <= 268435455	-134217728 <= value <= 134217727
5	value < 0 || value > 268435455	value < -134217728 || value > 134217727

Method Detail

readObjectData

public java.lang.Integer readObjectData(java.nio.ByteBuffer buffer,
                                        java.lang.Class type)

Description copied from class: Serializer

Reads an object from the buffer.

Specified by:

readObjectData in class Serializer

Returns:

The deserialized object, never null.

writeObjectData

public void writeObjectData(java.nio.ByteBuffer buffer,
                            java.lang.Object object)

Description copied from class: Serializer

Writes the object to the buffer.

Specified by:

writeObjectData in class Serializer

object - Cannot be null.

put

public static int put(java.nio.ByteBuffer buffer,
                      int value,
                      boolean optimizePositive)

Writes the specified int to the buffer using 1 to 5 bytes, depending on the size of the number.

Parameters:

optimizePositive - See IntSerializer(boolean).

Returns:

the number of bytes written.

get

public static int get(java.nio.ByteBuffer buffer,
                      boolean optimizePositive)

Reads an int from the buffer that was written with put(ByteBuffer, int, boolean).

canRead

public static boolean canRead(java.nio.ByteBuffer buffer,
                              boolean optimizePositive)

Reads true if the buffer contains enough data to read an int that was written with put(ByteBuffer, int, boolean).

length

public static int length(int value,
                         boolean optimizePositive)

Reads true if the buffer contains enough data to read an int that was written with put(ByteBuffer, int, boolean).
