Method Detail

equal

public static final int equal(ArrowBuf left,
        int lStart,
        int lEnd,
        ArrowBuf right,
        int rStart,
        int rEnd)

Helper function to check for equality of bytes in two ArrowBufs

Parameters:

left - Left ArrowBuf for comparison

lStart - start offset in the buffer

lEnd - end offset in the buffer

right - Right ArrowBuf for comparison

rStart - start offset in the buffer

rEnd - end offset in the buffer

Returns:

1 if left input is greater, -1 if left input is smaller, 0 otherwise

compare

public static final int compare(ArrowBuf left,
          int lStart,
          int lEnd,
          ArrowBuf right,
          int rStart,
          int rEnd)

Helper function to compare a set of bytes in two ArrowBufs. Function will check data before completing in the case that

Parameters:

left - Left ArrowBuf to compare

lStart - start offset in the buffer

lEnd - end offset in the buffer

right - Right ArrowBuf to compare

rStart - start offset in the buffer

rEnd - end offset in the buffer

Returns:

1 if left input is greater, -1 if left input is smaller, 0 otherwise

compare

public static final int compare(ArrowBuf left,
          int lStart,
          int lEnd,
          byte[] right,
          int rStart,
          int rEnd)

Helper function to compare a set of bytes in ArrowBuf to a ByteArray.

Parameters:

left - Left ArrowBuf for comparison purposes

lStart - start offset in the buffer

lEnd - end offset in the buffer

right - second input to be compared

rStart - start offset in the byte array

rEnd - end offset in the byte array

Returns:

1 if left input is greater, -1 if left input is smaller, 0 otherwise
