## 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

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

Default constructor.

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

Advanced constructor.

Ogre::Exception::Exception | ( | const Exception & | rhs | ) |

Copy constructor.

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

Needed for compatibility with std::exception.

Definition at line 128 of file OgreException.h.

## Member Function Documentation

void Ogre::Exception::operator= | ( | const Exception & | rhs | ) |

Assignment operator.

virtual const String& Ogre::Exception::getFullDescription | ( | void |  | ) | const`[virtual]`

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.

virtual int Ogre::Exception::getNumber | ( | void |  | ) | const throw ()`[virtual]`

Gets the error code.

virtual const String& Ogre::Exception::getSource | ( | void |  | ) | const`[virtual]`

Gets the source function.

Definition at line 152 of file OgreException.h.

virtual const String& Ogre::Exception::getFile | ( |  | ) | const`[virtual]`

Gets source file name.

Definition at line 156 of file OgreException.h.

virtual long Ogre::Exception::getLine | ( |  | ) | const`[virtual]`

Gets line number.

Definition at line 160 of file OgreException.h.

virtual const String& Ogre::Exception::getDescription | ( | void |  | ) | const`[virtual]`

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.

Definition at line 166 of file OgreException.h.

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

Override std::exception::what.
