Constructor Detail

DataBufferByte

public DataBufferByte(com.jniwrapper.MemoryBuffer buffer,
                      int size)

Constructs a byte-based DataBuffer with a single bank using the specified MemoryBuffer. Only the first size elements should be used by accessors of this DataBuffer. MemoryBuffer must be large enough to hold size elements.

Parameters:

buffer - The memory buffer with allocate byte array for the DataBuffer.

size - The size of the DataBuffer bank.

DataBufferByte

public DataBufferByte(byte[] buffer)

Constructs a byte-based DataBuffer with a single bank using the specified MemoryBuffer. Only the first size elements should be used by accessors of this DataBuffer. MemoryBuffer must be large enough to hold size elements.

Parameters:

buffer - data buffer

public byte[] getData()

Returns the default (first) byte data array.

Returns:

The first byte data array.

getData

public byte[] getData(int bank)

Returns the data array for the specified bank.

Parameters:

bank - The bank whose data array you want to get.

Returns:

The data array for the specified bank.

getBankData

public byte[][] getBankData()

Returns the data arrays for all banks.

Returns:

All of the data arrays.

getElem

public int getElem(int i)

Returns:

The requested data array element as an integer.

getElem

public int getElem(int bank,
                   int i)

Returns the requested data array element from the specified bank.

Specified by:

getElem in class java.awt.image.DataBuffer

Parameters:

bank - The bank from which you want to get a data array element.

i - The data array element you want to get.

Returns:

The requested data array element as an integer.

setElem

public void setElem(int i,
                    int val)

                    int i,
                    int val)

Sets the requested data array element in the specified bank from the given integer.

Specified by:

setElem in class java.awt.image.DataBuffer

Parameters:

bank - The bank in which you want to set the data array element.

i - The data array element you want to set.

val - The integer value to which you want to set the specified data array element.
