public class DataBufferFloat extends DataBuffer (Code)
	An extension of `DataBuffer` that stores data internally in `float` form. See Also: java.awt.image.DataBuffer

Field Summary
protected float	bankdata The array of data banks.
protected float	data A reference to the default data bank.

Constructor Summary
public	DataBufferFloat(int size) Constructs a `float`-based `DataBuffer` with a specified size.
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.
public	DataBufferFloat(float dataArray, int size) Constructs a `float`-based `DataBuffer` with the specified data array.
public	DataBufferFloat(float dataArray, int size, int offset) Constructs a `float`-based `DataBuffer` with the specified data array.
public	DataBufferFloat(float dataArray, int size) Constructs a `float`-based `DataBuffer` with the specified data arrays.

	A reference to the default data bank.

Constructor Detail

DataBufferFloat
public DataBufferFloat(int size)(Code)
	Constructs a `float`-based `DataBuffer` with a specified size. Parameters: size - The number of elements in the `DataBuffer`.

DataBufferFloat
public DataBufferFloat(int size, int numBanks)(Code)
	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`. Parameters: numBanks - The number of banks in the`DataBuffer`.

DataBufferFloat
public DataBufferFloat(float dataArray, int size)(Code)
	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. Parameters: dataArray - An array of `float`s to be used as thefirst and only bank of this `DataBuffer`. Parameters: size - The number of elements of the array to be used.

DataBufferFloat
public DataBufferFloat(float dataArray, int size, int offset)(Code)
	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. Parameters: dataArray - An array of `float`s to be used as thefirst and only bank of this `DataBuffer`. Parameters: size - The number of elements of the array to be used. Parameters: offset - The offset of the first element of the arraythat will be used.

DataBufferFloat
public DataBufferFloat(float dataArray, int size)(Code)
	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`. Parameters: dataArray - An array of arrays of `float`s to beused as the banks of this `DataBuffer`. Parameters: size - The number of elements of each array to be used.

DataBufferFloat
public DataBufferFloat(float dataArray, int size, int offsets)(Code)
	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. Parameters: dataArray - An array of arrays of `float`s to beused as the banks of this `DataBuffer`. Parameters: size - The number of elements of each array to be used.
