Method Detail

hash

public static <T> long hash(T input,
            Access<T> access,
            long offset,
            long length)

Returns the hash code for len continuous bytes of the given input object, starting from the given offset. The abstraction of input as ordered byte sequence and "offset within the input" is defined by the given access strategy.

This method doesn't promise to throw a RuntimeException if [off, off + len - 1] subsequence exceeds the bounds of the bytes sequence, defined by access strategy for the given input, so use this method with caution.

Type Parameters:

T - the type of the input

Parameters:

input - the object to read bytes from

access - access which defines the abstraction of the given input as ordered byte sequence

offset - offset to the first byte of the subsequence to hash

length - length of the subsequence to hash

Returns:

hash code for the specified bytes subsequence
