DataBufferUShort
public DataBufferUShort(int size) Constructs an unsigned-short basedDataBufferwith a single bank and the specified size.- Parameters:
size- The size of theDataBuffer.
-
DataBufferUShort
public DataBufferUShort(int size, int numBanks) Constructs an unsigned-short basedDataBufferwith the specified number of banks, all of which are the specified size.- Parameters:
size- The size of the banks in theDataBuffer.numBanks- The number of banks in theDataBuffer.
-
DataBufferUShort
public DataBufferUShort(short[] dataArray, int size) Constructs an unsigned-short basedDataBufferwith a single bank using the specified array. Only the firstsizeelements should be used by accessors of thisDataBuffer.dataArraymust be large enough to holdsizeelements.Note that
DataBufferobjects 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- The unsigned-short array for theDataBuffer.size- The size of theDataBufferbank.
-
DataBufferUShort
public DataBufferUShort(short[] dataArray, int size, int offset) Constructs an unsigned-short basedDataBufferwith a single bank using the specified array, size, and offset.dataArraymust have at leastoffset+sizeelements. Only elementsoffsetthroughoffset+size- 1 should be used by accessors of thisDataBuffer.Note that
DataBufferobjects 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- The unsigned-short array for theDataBuffer.size- The size of theDataBufferbank.offset- The offset into thedataArray.
-
DataBufferUShort
public DataBufferUShort(short[][] dataArray, int size) Constructs an unsigned-short basedDataBufferwith the specified arrays. The number of banks will be equal todataArray.length. Only the firstsizeelements of each array should be used by accessors of thisDataBuffer.Note that
DataBufferobjects 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- The unsigned-short arrays for theDataBuffer.size- The size of the banks in theDataBuffer.
-
DataBufferUShort
public DataBufferUShort(short[][] dataArray, int size, int[] offsets) Constructs an unsigned-short basedDataBufferwith specified arrays, size, and offsets. The number of banks is equal todataArray.length. Each array must be at least as large assize+ the corresponding offset. There must be an entry in the offset array for eachdataArrayentry. For each bank, only elementsoffsetthroughoffset+size- 1 should be used by accessors of thisDataBuffer.Note that
DataBufferobjects 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- The unsigned-short arrays for theDataBuffer.size- The size of the banks in theDataBuffer.offsets- The offsets into each array.

getData
public short[] getData()Returns the default (first) unsigned-short data array.Note that calling this method may cause this
DataBufferobject to be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).- Returns:
- The first unsigned-short data array.
-
getData
public short[] getData(int bank) Returns the data array for the specified bank.Note that calling this method may cause this
DataBufferobject to be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).- Parameters:
bank- The bank whose data array you want to get.- Returns:
- The data array for the specified bank.
-
getBankData
public short[][] getBankData()Returns the data arrays for all banks.Note that calling this method may cause this
DataBufferobject to be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).- Returns:
