Detailed Description

When thrown, provides information about an error that has occurred inside the engine.

Remarks

OGRE never uses return values to indicate errors. Instead, if an error occurs, an exception is thrown, and this is the object that encapsulates the detail of the problem. The application using OGRE should always ensure that the exceptions are caught, so all OGRE engine functions should occur within a try{} catch(Ogre::Exception& e) {} block.

The user application should never create any instances of this object unless it wishes to unify its error handling using the same object.

Constructor & Destructor Documentation

Exception() [1/3]

Ogre::Exception::Exception	(	int	number,
		const String &	description,
		const String &	source
	)

Default constructor.

Exception() [2/3]

Ogre::Exception::Exception	(	int	number,
		const String &	description,
		const String &	source,
		const char *	type,
		const char *	file,
		long	line
	)

Advanced constructor.

Exception() [3/3]

Ogre::Exception::Exception

(

const Exception &

rhs

)

Copy constructor.

~Exception()

Ogre::Exception::~Exception ( ) throw ( )

inline

Needed for compatibility with std::exception.

Member Function Documentation

getFullDescription()

const String& Ogre::Exception::getFullDescription ( void  ) const

inline

Returns a string with the full description of this error.

Remarks

The description contains the error number, the description supplied by the thrower, what routine threw the exception, and will also supply extra platform-specific information where applicable. For example - in the case of a rendering library error, the description of the error will include both the place in which OGRE found the problem, and a text description from the 3D rendering library, if available.

getSource()

const String& Ogre::Exception::getSource ( ) const

inline

Gets the source function.

getFile()

const char* Ogre::Exception::getFile ( ) const

inline

Gets source file name.

getLine()

long Ogre::Exception::getLine ( ) const

inline

Gets line number.

getDescription()

const String& Ogre::Exception::getDescription ( void  ) const

inline

Returns a string with only the 'description' field of this exception.

Use getFullDescriptionto get a full description of the error including line number, error number and what function threw the exception.

what()

const char* Ogre::Exception::what ( ) const throw ( )
