equals

public boolean equals(Object obj)

Description copied from class: ArrayRef

Note that since this class is basically a glorified pointer, the Equals method merely checks that they both point to the same memory location.
The fact that two ArrayRef objects point at different buffers does not mean that the pointed-to contents are unequal in terms of their own array-class semantics, but they are unequal from the point of view of this class, so if you are interested in that sort of equality, this method is not relevant.
Subclasses of ArrayRef must override this method, if they are in a position to know what their array type is and expect equals() to take the buffer contents into account.

Overrides:

equals in class ArrayRef<byte[]>

canEqual

public boolean canEqual(Object obj)

Overrides:

canEqual in class ArrayRef<byte[]>

equalsBytes

public boolean equalsBytes(byte[] barr,
                           int boff,
                           int blen)

arraySize

protected static int arraySize(byte[] buf)
