## Detailed Description

An unidirectional data translator (codec)

A factory for constructing data translators by format name conversion of data from one type to another

## Constructor & Destructor Documentation

TranslatorFactory | ( | const char * | name = `0` | ) |
| inlineexplicitprotected

Constructor - registers the factory in the global list

Parameters

  name | Static name of the factory, used for debugging

References Thread::getCurrentObjCounter(), and DataTranslator::install().

virtual ~TranslatorFactory | ( |  | ) |
| virtual

Destructor - unregisters from the global list

## Member Function Documentation

virtual bool converts | ( | const DataFormat & | sFormat,
|  | const DataFormat & | dFormat
| ) |  | const
| virtual

Check if this factory can build a translator for given data formats

Parameters

  sFormat | Name of the source format
  dFormat | Name of the destination format

Returns
  True if a conversion between formats is possible

virtual DataTranslator* create | ( | const DataFormat & | sFormat,
|  | const DataFormat & | dFormat
| ) |  |
| pure virtual

Creates a translator given the source and destination format names

Parameters

  sFormat | Name of the source format (data received from the consumer)
  dFormat | Name of the destination format (data supplied to the source)

Returns
  A pointer to the end of a DataTranslator chain or NULL

virtual const TranslatorCaps* getCapabilities | ( |  | ) | const
| pure virtual

Get the capabilities table of this translator

Returns
  A pointer to the first element of the capabilities table

virtual bool intermediate | ( | const FormatInfo * | info | ) | const
| virtual

Check if a data format is used as intermediate in a translator chain

Parameters

  info | Format to check for

Returns
  True if the format is used internally as intermediate

virtual const FormatInfo* intermediate | ( |  | ) | const
| virtual

Get the intermediate format used by a translator chain

Returns
  Pointer to intermediate format or NULL

virtual unsigned int length | ( |  | ) | const
| virtual

Get the length of the translator chain built by this factory

Returns
  How many translators will build the factory

virtual const char* name | ( |  | ) | const
| inlinevirtual

Get the name of this factory, useful for debugging purposes

Returns
  Name of the factory as specified in the constructor

NamedCounter* objectsCounter | ( |  | ) | const
| inline

Retrive the objects counter associated to this factory

Returns
  Pointer to factory's objects counter or NULL

virtual void removed | ( | const TranslatorFactory * | factory | ) |
| virtual

Notification that another factory was removed from the list

Parameters

  factory | Pointer to the factory that just got removed
