Public Member Functions | |
virtual bool | equals (Object::View v) const |
virtual size32_t | hashCode () const |
Return a hash code value for the Object. This method is supported for the benefit of hash-based containers.
The general contract of
The default implementation is identity based.
| |
virtual bool | isImmutable () const |
Return true iff no further changes can be made to the Object, that would effect the outcome of a call to its equals method.Except for Objects which are naturally immutable (such as String), being immutable generally implies that the Object is only referenced via const pointers or views. Objects which hold references to child Objects, may need to take the immutability of their children into account when determining their own immutability. This extended check is not performed by the default implementation, but can be integrated into the immutability checks by overriding this method, as well as making use of MemberHandles to reference child Objects. A typical derived implementation may look as follows:
bool isImmutable() const { if (m_fImmutable) // check recorded state { return true; // already marked as immutable, avoid calculation } else if (Object::isImmutable()) // ensure shallow immutability { // ensure deep immutability if (m_child1->isImmutable() && m_child2->isImmutable() ... && m_childN->isImmutable()) { // record and return immutability return m_fImmutable = true; } // some Objects which comprise this Object are still mutable } return false; } The default implementation return true iff the Object is only referenced via const pointers and or views.

virtual TypedHandle < const String > | toString () const |
Output a human-readable description of this Object to the given stream. Note that when overriding this method the return type must be TypedHandle<const String> rather then String::View. These two types are assignment compatible but not equivalent and declaring the override with String::View will not be a compatible override. coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toString method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents and is generally how toString() will be implemented.
Object::View vKey = ... Object::View vValue = ... std::cout << vKey << " = " << vValue << std::endl; String::View vs = COH_TO_STRING(vKey << " = " << vValue); The COH_TO_STRING macro is also the most common way to implement the toString method. For example:
virtual TypedHandle<const String> Person::toString() const { return COH_TO_STRING("Name: " << f_sName << " SSN: " << f_nSSN); }
