Field Detail

bankdata

protected float[][] bankdata

The array of data banks.

---

data

protected float[] data

A reference to the default data bank.

Constructor Detail

DataBufferFloat

public DataBufferFloat(int size)

Constructs a float-based DataBuffer with a specified size.

---

DataBufferFloat

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.

---

DataBufferFloat

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.

---

DataBufferFloat

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.

---

DataBufferFloat

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.

---

DataBufferFloat

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