StackTraceElement Class Reference

#include <coherence/lang/StackTraceElement.hpp>

Inherits Object.

List of all members.


Detailed Description

StackTraceElement interface represents a frame within a stack trace.

The information included in the trace is not of a guaranteed format and may differ between platforms and debug/release libraries. It is recommended that applications only print the element, and not attempt to interpret the output.

This interface is also a place holder and may grow over time to include certain pre-parsed information, such as file and line numbers, though the availability of this information would still not be guaranteed.

Public Member Functions

virtual TypedHandle
< const String
toString () const =0
 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
