Detailed Description

Statistics relating to a class.

Public Types

typedef spec::Handle

Handle

ClassStats Handle definition.

typedef spec::View

View

ClassStats View definition.

typedef spec::Holder

Holder

ClassStats Holder definition.

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 void

toStream (std::ostream &out) const

Output a human-readable description of this Object to the given stream.

coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toStream 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.

 Object::View vKey   = ...
 Object::View vValue = ...
 std::cout << vKey << " = " << vValue << std::endl;

 String::Handle hs = COH_TO_STRING(vKey << " = " << vValue);

Parameters:

out

the stream used to output the description

Protected Member Functions
