Public Member Functions

virtual int64_t

getObjectCount () const

Return the instance count for the class.

virtual int64_t

getByteCount () const

Return the byte count for the class.

virtual int64_t

getAllocationCount () const

Return the allocation count for the class.

int32_t

compareTo (Object::View v) const

Compare this object with the specified object for order.

Return a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object.

It is strongly recommended, but not strictly required, that (x->compareTo(y) == 0) == (x->equals(y)).

Parameters:

the Object to be compared

Returns:: a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object

Exceptions:

ClassCastException

if the specified Object's type prevents it from being compared to this Object

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);
     }

Returns:: a string representation of this object
