equal

@Deprecated
public static final int equal(ArrowBuf left,
                                          int lStart,
                                          int lEnd,

                                          int rEnd)

Deprecated.

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 equals, 0 otherwise

compare

                                            int rEnd)

Deprecated.

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

                                            int rEnd)

Deprecated.

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

unsignedLongCompare

@Deprecated
public static int unsignedLongCompare(long a,
                                                  long b)

Deprecated.

Compares the two specified long values, treating them as unsigned values between 0 and 2^64 - 1 inclusive.

Parameters:

a - the first unsigned long to compare

b - the second unsigned long to compare

Returns:

a negative value if a is less than b; a positive value if a is greater than b; or zero if they are equal
