Public Constructors

public DataBufferFloat (int size)

Constructs a float-based DataBuffer with a specified size.

Parameters
size The number of elements in the DataBuffer.

public DataBufferFloat (int size, int numBanks)

Constructs a float-based DataBuffer with a specified number of banks, all of which are of a specified size.

Parameters
size The number of elements in each bank of the DataBuffer.
numBanks The number of banks in the DataBuffer.

public DataBufferFloat (float[] dataArray, int size)

Constructs a float-based DataBuffer with the specified data array. Only the first size elements are available for use by this DataBuffer. The array must be large enough to hold size elements.

Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).

Parameters
dataArray An array of floats to be used as the first and only bank of this DataBuffer.
size The number of elements of the array to be used.

public DataBufferFloat (float[] dataArray, int size, int offset)

Constructs a float-based DataBuffer with the specified data array. Only the elements between offset and offset + size - 1 are available for use by this DataBuffer. The array must be large enough to hold offset + size elements.

Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).

Parameters
dataArray An array of floats to be used as the first and only bank of this DataBuffer.
size The number of elements of the array to be used.
offset The offset of the first element of the array that will be used.

public DataBufferFloat (float[][] dataArray, int size)

Constructs a float-based DataBuffer with the specified data arrays. Only the first size elements of each array are available for use by this DataBuffer. The number of banks will be equal to dataArray.length.

Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).

Parameters
dataArray An array of arrays of floats to be used as the banks of this DataBuffer.
size The number of elements of each array to be used.

public DataBufferFloat (float[][] dataArray, int size, int[] offsets)

Constructs a float-based DataBuffer with the specified data arrays, size, and per-bank offsets. The number of banks is equal to dataArray.length. Each array must be at least as large as size plus the corresponding offset. There must be an entry in the offsets array for each data array.

Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).

Parameters
dataArray An array of arrays of floats to be used as the banks of this DataBuffer.
size The number of elements of each array to be used.
offsets An array of integer offsets, one for each bank.
