Constructor Detail

SharedFloatMatrix

public SharedFloatMatrix(int rows,
                         int cols)

Constructs a rows-by-cols shared float matrix.

Parameters:

rows - Number of rows.

cols - Number of colums.

Method Detail

map

public FloatBuffer[] map()

Maps the shared memory cube of this shared memory matrix.

Specified by:

map in class SharedAbstractMatrix<SharedFloatMatrix>

Returns:

The mapped float buffer.

array

public float[][] array()

Returns the float array that backs this matrix. Modifications to the content of this matrix will not cause the returned array's content to be modified, and vice versa.

Returns:

The array that backs this matrix.

get

public float get(int i,
                 int j)

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

Parameters:

i - The row index from which the float will be read.

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

Returns:

The float at the given index.

get

public void get(float[][] array,
                int x,
                int y)

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

Parameters:

array - The float array at the given index.

x - The row index from which the float array will be read.

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

get

public void get(float[][] array)

Absolute bulk get method. Reads the float array.

Parameters:

array - The float array.

put

public void put(int i,
                int j,
                float value)

Absolute put method. Writes the given float into this matrix at the given index.

Parameters:

i - The row index at which the float will be written.

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

value - The float to be written.

put

public void put(float[][] array,
                int x,
                int y)

Absolute bulk put method. Writes the given float array into this matrix at the given index.

Parameters:

array - The float array to be written.

x - The row index at which the float array will be written.

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

put

public void put(float[][] array)

Absolute bulk put method. Writes the given float array into this matrix.

Parameters:

array - The float array to be written.

unit

public int unit()

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

Returns:

The unit size.
