Member Function Documentation

virtual void itk::LoggerBase::AddLogOutput ( OutputType * output ) [virtual]

Registers another output stream with the multiple output.
Reimplemented in itk::ThreadLogger.

static void itk::LightObject::BreakOnError ( ) [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

virtual std::string itk::LoggerBase::BuildFormattedEntry ( PriorityLevelType level,

std::string const & content

) [virtual]

Provides a default formatted log entry

virtual LightObject::Pointer itk::Object::CreateAnother ( ) const [virtual, inherited]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
Reimplemented from itk::LightObject.

void itk::LoggerBase::Critical ( std::string const & message ) [inline]

Definition at line 107 of file itkLoggerBase.h.
References CRITICAL.

Helper methods* void itk::LoggerBase::Debug ( std::string const & message ) [inline]

Definition at line 104 of file itkLoggerBase.h.
References DEBUG.

virtual void itk::Object::DebugOff ( ) const [virtual, inherited]

Turn debugging output off.

virtual void itk::Object::DebugOn ( ) const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete ( ) [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

void itk::LoggerBase::Error ( std::string const & message ) [inline]

Definition at line 108 of file itkLoggerBase.h.
References CRITICAL.

void itk::LoggerBase::Fatal ( std::string const & message ) [inline]

Definition at line 109 of file itkLoggerBase.h.
References FATAL.

virtual void itk::LoggerBase::Flush ( ) [virtual]

Reimplemented in itk::ThreadLogger.

Command* itk::Object::GetCommand ( unsigned long tag ) [inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

bool itk::Object::GetDebug ( ) const [inherited]

Get the value of the debug flag.

static bool itk::Object::GetGlobalWarningDisplay ( ) [static, inherited]

virtual PriorityLevelType itk::LoggerBase::GetLevelForFlushing ( ) const [inline, virtual]

Returns:
A constant reference to this objects MetaDataDictionary.

MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void ) [inherited]

Returns:
A reference to this objects MetaDataDictionary.

Warning:
This reference may be changed.

virtual unsigned long itk::Object::GetMTime ( ) const [virtual, inherited]

Return this objects modified time.
Reimplemented in itk::ImageRegistrationMethod< TFixedImage, TMovingImage >, itk::DeformationFieldSource< TOutputImage >, itk::InverseDeformationFieldImageFilter< TInputImage, TOutputImage >, itk::ResampleImageFilter< TInputImage, TOutputImage, TInterpolatorPrecisionType >, itk::VectorResampleImageFilter< TInputImage, TOutputImage, TInterpolatorPrecisionType >, itk::BoundingBox< TPointIdentifier, VPointDimension, TCoordRep, TPointsContainer >, itk::SceneSpatialObject< SpaceDimension >, and itk::SceneSpatialObject< NDimensions >.

virtual const char* itk::LoggerBase::GetName ( ) const [virtual]

virtual const char* itk::LoggerBase::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).
Reimplemented from itk::Object.
Reimplemented in itk::Logger, and itk::ThreadLogger.

virtual PriorityLevelType itk::LoggerBase::GetPriorityLevel ( ) const [inline, virtual]

Get the priority level for the current logger. Only messages that have priorities equal or greater than the one set here will be posted to the current outputs
Reimplemented in itk::ThreadLogger.
Definition at line 83 of file itkLoggerBase.h.

virtual int itk::LightObject::GetReferenceCount ( ) const [inline, virtual, inherited]

Gets the reference count on this object.

void itk::Object::InvokeEvent ( const EventObject & ) const [inherited]

Call Execute on all the Commands observing this event id. The actions triggered by this call doesn't modify this object.

void itk::Object::InvokeEvent ( const EventObject & ) [inherited]

Call Execute on all the Commands observing this event id.
