Member Function Documentation

virtual void jem::Boolean::readFrom ( io::ObjectInput in)
virtual

Implements jem::io::Serializable.

virtual void jem::Boolean::writeTo ( io::ObjectOutput out) const
virtual

Implements jem::io::Serializable.

virtual String jem::Boolean::toString ( ) const
virtual

Returns a short textual description of this object. The toString method of the class Object returns:

getClass()->getName() + "@" + String( hashValue() )

Returns
A String representing this object.

Reimplemented from jem::Object.

virtual lint jem::Boolean::hashValue ( ) const
virtual

Returns a hash value for this object. This function should return the same hash value when it is invoked more than once on the same object, provided that the object is not modified. If two object are equal according to the equals method, then those objects should return the same hash value. Note that two objects which are not equal may also return the same hash value.

The hashValue implementation of the Object class returns a hash value for the memory address of the object.

Returns
A long integer representing the hash value of this object.

Reimplemented from jem::Object.

virtual bool jem::Boolean::equals ( const Ref< Object > &  obj) const
virtual

Tests whether this Object is equal to the Object obj. The equals method should be:

  • reflexive: for all objects x, x->equals(x) should return true.
  • symmetric: for all objects x and y, x->equals(y) should return the same value as y->equals(x).
  • transitive: if, for any objects x, y, and z, x->equals(y) returns true and y->equals(z) returns true, then x->equals(z) should return true.
  • consistent: for all objects x and y, multiple invocations of x->equals(y) should return the same value as long as the objects are not modified.

In addition, x->equals(NIL) should return false for all objects x.

The default implementation of equals returns true if and only if this object and the argument obj are located at the same memory address. That is, the default implementation returns (this == obj).

Parameters
obj- the object this object should be compared to, or NIL.
Returns
true is this object equals the object obj, and false otherwise.

Reimplemented from jem::Object.
