Method Detail

arrayCopyUnequal

public static void arrayCopyUnequal(java.lang.Object arr1,
                                    int offset1,
                                    java.lang.Object arr2,
                                    int offset2,
                                    int length)

Copy the common LSBytes of one array type into another. If the destination has more bytes than the source, the upper bytes are set to zero. If the destination has less bytes than the source, the upper bytes are truncated.

Parameters:

arr1 -

offset1 -

arr2 -

offset2 -

length -

Returns:

arrayComp

public static boolean arrayComp(byte[] str1,
                                int offset1,
                                byte[] str2,
                                int offset2,
                                int length)

Quick function to compare two byte arrays.

Parameters:

str1 - first array

offset1 - first array starting offset

str2 - second array

offset2 - second array starting offset

length - number of bytes to compare

Returns:

true if arrays compare favorably.

arrayComp

public static boolean arrayComp(char[] str1,
                                int offset1,
                                char[] str2,
                                int offset2,
                                int length)

Deprecated.

Quick function to compare a character array to a byte array. This only looks at the LSB of the character vs. the byte in the other array.

Parameters:

str1 - first array

offset1 - first array starting offset

str2 - second array

offset2 - second array starting offset

length - number of bytes to compare

Returns:

true if arrays compare favorably.

arrayFill

public static void arrayFill(byte[] a,
                             int fromIndex,
                             int toIndex,
                             byte val)
