Constructor Detail

SharedByteVector

public SharedByteVector(int cols)

Constructs a 1-by-cols shared byte vector.

Parameters:

cols - Number of colums.

Method Detail

map

public ByteBuffer[] map()

Maps the shared memory cube of this shared memory vector.

Specified by:

map in class SharedAbstractVector<SharedByteVector>

Returns:

The mapped byte buffer.

array

public byte[] array()

Returns the byte array that backs this vector. Modifications to the content of this vector will not cause the return array's content to be modified, and vice versa.

Returns:

The array that backs this vector.

get

public byte get(int j)

Absolute get method. Reads the byte at the given index.

Parameters:

j - The column index from which the byte will be read.

Returns:

The byte at the given index.

get

public void get(byte[] array,
                int y)

Absolute bulk get method. Reads the byte array at the given index.

Parameters:

array - The byte array at the given index.

y - The column index from which the byte array will be read.

get

public void get(byte[] array)

Absolute bulk get method. Reads the byte array.

Parameters:

array - The byte array.

put

public void put(int j,
                byte value)

Absolute put method. Writes the given byte into this vector at the given index.

Parameters:

j - The column index at which the byte will be written.

value - The byte to be written.

put

public void put(byte[] array,
                int y)

Absolute bulk put method. Writes the given byte array into this vector at the given index.

Parameters:

array - The byte array to be written.

y - The column index at which the byte array will be written.

put

public void put(byte[] array)

Absolute bulk put method. Writes the given byte array into this vector.

Parameters:

array - The byte array to be written.

unit

public int unit()

Returns the unit size (in bytes) of this shared vector.

Returns:

The unit size.
