Method Details

equals

public static boolean equals(char[] x,
 int xmin,
 int xmax,
 char[] y,
 int ymin,
 int ymax)

Checks if the two arrays are equal within the given range.

Parameters:

x - the first array

xmin - the inclusive minimum of the range of the first array

xmax - the exclusive maximum of the range of the first array

y - the second array

ymin - the inclusive minimum of the range of the second array

ymax - the exclusive maximum of the range of the second array

Returns:

true if the arrays are equal in the specified ranges

mismatch

public static int mismatch(byte[] a,
 int aFromIndex,
 int aToIndex,
 byte[] b,
 int bFromIndex,
 int bToIndex)

Finds and returns the relative index of the first mismatch between two byte arrays over the specified ranges,otherwise return -1 if no mismatch is found. The index will be in the range of 0 (inclusive) up to the length (inclusive) of the smaller range.

Parameters:

a - one input byte array

aFromIndex - inclusive

aToIndex - exclusive

b - another input byte array

bFromIndex - inclusive

bToIndex - exclusive

Returns:

-1 if no mismatch found,otherwise the mismatch offset
