Method Detail

writeSize

public static final void writeSize(int s,
                                   ByteBuffer buffer,
                                   SerializableControl flusher)

Serialize the specified array size into the specified buffer, flushing when necessary. The specified SerializableControl manages any flushing required.

Parameters:

s - size to encode

buffer - the buffer to be serialized into

flusher - the SerializableControl to manage the flushing

readSize

public static final int readSize(ByteBuffer buffer,
                                 DeserializableControl control)

Deserialize the array size from the specified buffer. The specified DeserializableControl ensures sufficient bytes are available.

Parameters:

buffer - the buffer to serialize from

control - the DeserializableControl

Returns:

the deserialized array size

readSize

public static final int readSize(ByteBuffer buffer)

Deserialize the array size from the specified buffer.

Parameters:

buffer - the buffer to serialize from

Returns:

the deserialized array size

serializeString

public static final void serializeString(String value,
                                         ByteBuffer buffer,
                                         SerializableControl flusher)

Serialize the specified string into the specified buffer, flushing when necessary. The specified SerializableControl manages any flushing required.

Parameters:

value - the string to be serialized

buffer - the buffer to be serialized into

flusher - the SerializableControl to manage the flushing

serializeString

public static final void serializeString(String value,
                                         ByteBuffer buffer)

Serialize the specified string into the specified buffer.

Parameters:

value - the string to be serialized

buffer - the buffer to be serialized into

serializeSubstring

public static final void serializeSubstring(String value,
                                            int offset,
                                            int count,
                                            ByteBuffer buffer,
                                            SerializableControl flusher)

Serialize a substring of a specified string into the specified buffer, flushing when necessary. The substring serialized is of the specified length and starts at the specified offset relative to supplied string. The specified SerializableControl manages any flushing required.

Parameters:

value - the string from which a substring is to be serialized

offset - the start of the substring relative to supplied string

count - the length of the substring

buffer - the buffer to be serialized into

flusher - the SerializableControl to manage the flushing

deserializeString

public static final String deserializeString(ByteBuffer buffer,
                                             DeserializableControl control)

Deserialize a string from the specified buffer. The specified DeserializableControl ensures sufficient bytes are available.

Parameters:

buffer - the buffer to serialize from

control - the DeserializableControl

Returns:

the deserialized string

deserializeString

public static final String deserializeString(ByteBuffer buffer)

Deserialize a string from the specified buffer.

Parameters:

buffer - the buffer to serialize from

Returns:

the deserialized string
