Public Methods

public abstract boolean booleanValue ()

Converts this value to a BooleanValue and returns the result as a boolean.

Returns
  • true if this value is non-zero (or true if already a BooleanValue); false otherwise.

public abstract byte byteValue ()

Converts this value to a ByteValue and returns the result as a byte. The value will be narrowed as necessary, and magnitude or precision information may be lost (as if the primitive had been cast to a byte).

Returns
  • the value, converted to byte

public abstract char charValue ()

Converts this value to a CharValue and returns the result as a char. The value will be narrowed or widened as necessary, and magnitude or precision information may be lost (as if the primitive had been cast to a char, in the narrowing case).

Returns
  • the value, converted to char

public abstract double doubleValue ()

Converts this value to a DoubleValue and returns the result as a double. The value will be widened as necessary, and precision information may be lost.

Returns
  • the value, converted to double

public boolean equals (Object obj)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values 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.
  • For any non-null reference value 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.

Parameters
obj the reference object with which to compare.
Returns
  • true if this object is the same as the obj argument; false otherwise.

public abstract float floatValue ()

Converts this value to a FloatValue and returns the result as a float. The value will be narrowed or widened as necessary, and magnitude or precision information may be lost (as if the primitive had been cast to a float, in the narrowing case).

Returns
  • the value, converted to float

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the 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.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the 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 hashtables.

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.)

Returns
  • a hash code value for this object.

public abstract int intValue ()

Converts this value to an IntegerValue and returns the result as an int. The value will be narrowed or widened as necessary, and magnitude or precision information may be lost (as if the primitive had been cast to an int, in the narrowing case).

Returns
  • the value, converted to int

public abstract long longValue ()

Converts this value to a LongValue and returns the result as a long. The value will be narrowed or widened as necessary, and magnitude or precision information may be lost (as if the primitive had been cast to a long, in the narrowing case).

Returns
  • the value, converted to long

public abstract short shortValue ()

Converts this value to a ShortValue and returns the result as a short. The value will be narrowed or widened as necessary, and magnitude or precision information may be lost (as if the primitive had been cast to a short, in the narrowing case).

Returns
  • the value, converted to short

public VirtualMachine virtualMachine ()

Gets the VirtualMachine to which this Mirror belongs. A Mirror must be associated with a VirtualMachine to have any meaning.

Returns
