public class CborType extends Object
The major type is encoded in the upper three bits of each initial byte. The lower 5 bytes represent any additional information.

public boolean equals(@Nullable Object obj)

The equals
method implements an equivalence relation on non-null object references:
x
, x.equals(x)
should return true
.
x
and y
,
x.equals(y)
should return true
if and only if y.equals(x)
returns
true
.
x
, y
, and
z
, if x.equals(y)
returns true
and y.equals(z)
returns
true
, then x.equals(z)
should return true
.
x
and y
, multiple
invocations of x.equals(y)
consistently return true
or consistently return
false
, provided no information used in equals
comparisons on the objects is
modified.
x
, x.equals(null)
should return
false
.
The equals
method for class Object
implements the most discriminating possible
equivalence relation on objects; that is, for any non-null reference values x
and
y
, this method returns true
if and only if x
and y
refer to the
same object (x == y
has the value true
).
Note that it is generally necessary to override the hashCode
method whenever this method
is overridden, so as to maintain the general contract for the hashCode
method, which
states that equal objects must have equal hash codes.

The general contract of hashCode
is:
hashCode
method must consistently return the same integer, provided no
information used in equals
comparisons on the object is modified. This integer need not
remain consistent from one execution of an application to another execution of the same
application.

method, then calling the
hashCode
method on each of the two objects must produce the same integer result.
Object.equals(java.lang.Object)
method, then calling the hashCode
method on each of the two objects must produce distinct integer results. However, the programmer
should be aware that producing distinct integer results for unequal objects may improve the
performance of hash tables.
As much as is reasonably practical, the hashCode method defined by class Object
does
return distinct integers for distinct objects. (This is typically implemented by converting the
internal address of the object into an integer, but this implementation technique is not required
by the JavaTM programming language.)

Object
toString
method returns a
string that "textually represents" this object. The result should be a concise but informative
representation that is easy for a person to read. It is recommended that all subclasses override
this method.
The toString
method for class Object
returns a string consisting of the name of
the class of which the object is an instance, the at-sign character `@
', and the unsigned
hexadecimal representation of the hash code of the object. In other words, this method returns a
string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
