DataBufferInt

public final class DataBufferInt extends DataBuffer
This class extends DataBuffer and stores data internally as integers.

Fields Summary
int[]
data
The default data bank.
int[]
bankdata
All data banks
Constructors Summary
public DataBufferInt(int size)
Constructs an integer-based DataBuffer with a single bank and the specified size.

param
size The size of the DataBuffer.

        super(TYPE_INT,size);
        data = new int[size];
        bankdata = new int[1][];
        bankdata[0] = data;
    
public DataBufferInt(int size, int numBanks)
Constructs an integer-based DataBuffer with the specified number of banks, all of which are the specified size.

param
size The size of the banks in the DataBuffer.
param
numBanks The number of banks in the aDataBuffer.

        super(TYPE_INT,size,numBanks);
        bankdata = new int[numBanks][];
        for (int i= 0; i < numBanks; i++) {
            bankdata[i] = new int[size];
        }
        data = bankdata[0];
    
public DataBufferInt(int[] dataArray, int size)
Constructs an integer-based DataBuffer with a single bank using the specified array. Only the first size elements should be used by accessors of this DataBuffer. dataArray must be large enough to hold size elements.

param
dataArray The integer array for the DataBuffer.
param
size The size of the DataBuffer bank.

        super(TYPE_INT,size);
        data = dataArray;
        bankdata = new int[1][];
        bankdata[0] = data;
    
public DataBufferInt(int[] dataArray, int size, int offset)
Constructs an integer-based DataBuffer with a single bank using the specified array, size, and offset. dataArray must have at least offset + size elements. Only elements offset through offset + size - 1 should be used by accessors of this DataBuffer.

param
dataArray The integer array for the DataBuffer.
param
size The size of the DataBuffer bank.
param
offset The offset into the dataArray.

        super(TYPE_INT,size,1,offset);
        data = dataArray;
        bankdata = new int[1][];
        bankdata[0] = data;
    
public DataBufferInt(int[] dataArray, int size)
Constructs an integer-based DataBuffer with the specified arrays. The number of banks will be equal to dataArray.length. Only the first size elements of each array should be used by accessors of this DataBuffer.

param
dataArray The integer arrays for the DataBuffer.
param
size The size of the banks in the DataBuffer.

        super(TYPE_INT, size, dataArray.length);
        bankdata = (int [][]) dataArray.clone();
        data = bankdata[0];
    
public DataBufferInt(int[] dataArray, int size, int[] offsets)
Constructs an integer-based DataBuffer with the specified arrays, size, and offsets. The number of banks is equal to dataArray.length. Each array must be at least as large as size + the corresponding offset. There must be an entry in the offset array for each dataArray entry. For each bank, only elements offset through offset + size - 1 should be used by accessors of this DataBuffer.

param
dataArray The integer arrays for the DataBuffer.
param
size The size of the banks in the DataBuffer.
param
offsets The offsets into each array.

        super(TYPE_INT,size,dataArray.length,offsets);
        bankdata = (int [][]) dataArray.clone();
        data = bankdata[0];
