Enclosing class:

CompressionFactory

public static interface CompressionFactory.LongEncodingReader

Method Summary

Modifier and Type	Method and Description
CompressionFactory.LongEncodingReader	duplicate() Duplicates this reader, creating a new reader that does not share any state.
long	read(int index)
int	read(long[] out, int outPosition, int[] indexes, int length, int indexOffset, int limit)
void	read(long[] out, int outPosition, int startIndex, int length)
void	setBuffer(ByteBuffer buffer)

Method Detail

setBuffer

void setBuffer(ByteBuffer buffer)

read

long read(int index)

read

void read(long[] out,
          int outPosition,
          int startIndex,
          int length)

read

int read(long[] out,
         int outPosition,
         int[] indexes,
         int length,
         int indexOffset,
         int limit)

duplicate

CompressionFactory.LongEncodingReader duplicate()

Duplicates this reader, creating a new reader that does not share any state. Important to achieve thread-safety, because a common pattern is to duplicate a reader multiple times and then call setBuffer(java.nio.ByteBuffer) on the various duplicates.
