Constructor Details- 
DataBufferUShortpublic DataBufferUShort(int size) Constructs an unsigned-short basedDataBufferwith a single bank and the specified size.- Parameters:
- size- The size of the- DataBuffer.
 
- 
DataBufferUShortpublic 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 the- DataBuffer.
- numBanks- The number of banks in the- DataBuffer.
 
- 
DataBufferUShortpublic 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 the- DataBuffer.
- size- The size of the- DataBufferbank.
 
- 
DataBufferUShortpublic 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 the- DataBuffer.
- size- The size of the- DataBufferbank.
- offset- The offset into the- dataArray.
 
- 
DataBufferUShortpublic 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 the- DataBuffer.
- size- The size of the banks in the- DataBuffer.
 
- 
DataBufferUShortpublic 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 the- DataBuffer.
- size- The size of the banks in the- DataBuffer.
- offsets- The offsets into each array.
