Method Detail

create

public static StoLongField create(String name)

Create an STO long field.

Parameters:

name - The name of the field. A value of null will cause an unnamed field to be created.

create

public static StoLongField create(ByteBuffer buffer,
                                  int bufferOffset)

Create an STO long field from its serialized form.

Parameters:

buffer - The buffer containing the serialized field.

bufferOffset - The offset into the buffer where the serialized form of the field begins.

getSerializedLength

public static int getSerializedLength(ByteBuffer buffer,
                                      int offset)

Get the length of a serialized long value.

Parameters:

buffer - The buffer containing the serialized value.

offset - The offset into the buffer where the value is serialized.

This method leaves the buffer markers intact.

put

public static void put(ByteBuffer buffer,
                       int offset,
                       long val)

Serialize a long value.

Parameters:

buffer - The buffer in which to serialize the value.

offset - The offset into the buffer at which point to serialize the value.

This method leaves the buffer markers intact.

get

public static long get(ByteBuffer buffer,
                       int offset)

Deserialize a long value.

Parameters:

buffer - The buffer from which to deserialize the value.

offset - The offset into the buffer from which to deserialize the value.

This method leaves the buffer markers intact.

isVariableLength

public final boolean isVariableLength()

Implementation of StoField.isVariableLength()

Specified by:

isVariableLength in class StoField

reset

public final void reset()

Implementation of StoField.reset()

Specified by:

reset in class StoField

setValue

public final void setValue(long val)

Set the field value

Parameters:

val - The value to set.

getValue

public final long getValue()

Set the field value
