Public Member Functions | ||||
virtual bool | hasNext () const | |||
Determine if the iteration has another element.
| ||||
virtual Object::Holder | next () | |||
Return the next element in the iterated series.
| ||||
virtual void | remove () | |||
Remove from the collection associated with this iterator, the last element returned from the iterator.
| ||||
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); }
| ||||
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.
