Detailed Description

The SoError class is the base class for all the error handling classes.

The default error handler just prints messages on the standard error output channel, but this can be overridden by client applications.

Being able to override the default handler is useful when you want to collect error messages upon e.g. model import for later presentation of the messages to the user in any custom manner (like for instance in a GUI messagebox).

The SoError class is not designed to be particularly useful for "direct use". Within the Coin library it is only used through its subclasses.

Constructor & Destructor Documentation

~SoError()

SoError::~SoError ( )

inlinevirtual

The default destructor does nothing.

Member Function Documentation

setHandlerCallback()

void SoError::setHandlerCallback ( SoErrorCB *const  function, void *const  data  )

static

This method sets the error handler callback for messages posted via this class.

Note that this will not override the error/debug message handler for subclasses, these will have to be overrided by calling the subclass' setHandlerCallback() method.

defaultHandlerCB()

getHandlerCallback()

SoErrorCB * SoError::getHandlerCallback ( void  )

static

Returns the error handler callback for messages posted via this class.

getHandlerData()

void * SoError::getHandlerData ( void  )

static

This method returns the pointer used for passing data back to the callback handler method.

getDebugString()

const SbString & SoError::getDebugString

(

void

)

const

This method returns an SbString containing error info from the given error instance.

getClassTypeId()

SoType SoError::getClassTypeId ( void  )

static

This static method returns the SoType for this class.

See also

getTypeId()

getTypeId()

SoType SoError::getTypeId ( void  ) const

virtual

This method returns the SoType of a particular object instance.

See also

getClassTypeId()

Reimplemented in SoDebugError, SoReadError, and SoMemoryError.

isOfType()

SbBool SoError::isOfType

(

const SoType

type

)

const

This method returns TRUE if the error instance is of - or derived from - type, and FALSE otherwise.

post()

void SoError::post ( const char *const  format,   ...  )

static

This method posts an error message. The format string and the trailing aguments should follow the printf() standard.

getString() [1/3]

SbString SoError::getString ( const SoNode *const  node )

static

Constructs a string identifying the node with name (if available) and memory pointer.

getString() [2/3]

SbString SoError::getString ( const SoPath *const  path )

static

Constructs a string identifying the path with name (if available) and memory pointer.

getString() [3/3]

SbString SoError::getString ( const SoEngine *const  engine )

static

Constructs a string identifying the engine with name (if available) and memory pointer.

initClass()

void SoError::initClass ( void  )

static

This method takes care of initializing all static data for the class.

initClasses()

void SoError::initClasses ( void  )

static

This static method initializes all the SoError classes.

defaultHandlerCB()

void SoError::defaultHandlerCB ( const SoError *  error, void *  data  )

staticprotected

Contains the default code for handling error strings.

Default treatment of an error message is to print it out on the standard error file handle.

getHandler()

SoErrorCB * SoError::getHandler ( void *&  data ) const

protectedvirtual

This is just a convenience wrapper around the getHandlerCallback() and getHandlerData() methods.

Reimplemented in SoDebugError, SoReadError, and SoMemoryError.

setDebugString()

void SoError::setDebugString ( const char *const  str )

protected

Replace the latest stored debug string with str.

appendToDebugString()

void SoError::appendToDebugString ( const char *const  str )

protected

Add str at the end of the currently stored debug string.

handleError()

void SoError::handleError ( void  )

protected

This method calls the appropriate handler for an error instance. All error handling goes through this method, and is therefore a good candidate for a debugger breakpoint.
