Member Function Documentation

NamespaceURI()

virtual const char* NamespaceURI ( ) const

pure virtual

DoElement()

virtual bool DoElement ( const std::string &  ElName )

inlinevirtual

EndElement()

virtual bool EndElement ( const std::string &  ElName )

inlinevirtual

EndTag()

virtual const char* EndTag ( )

inlinevirtual

OutputToStream()

void OutputToStream ( )

inlineprotected

SkipObjects()

virtual int SkipObjects ( int  n, OBConversion *  pConv  )

inlineprotectedvirtual

Skip past first n objects in input stream (or current one with n=0) Returns 1 on success, -1 on error and 0 if not implemented

Reimplemented from OBFormat.

TypeID()

const char* TypeID ( )

inlinevirtualinherited

Redefined by each plugin type: "formats", "fingerprints", etc.

Reimplemented from OBPlugin.

ReadMolecule()

virtual bool ReadMolecule ( OBBase *  , OBConversion *    )

inlinevirtualinherited

The "API" interface Read function.

Reads a single object. Does not make a new object on the heap; can be used with a pointer to an chem object on the heap or the stack.

Reimplemented in XMLMoleculeFormat.

Referenced by OBMoleculeFormat::DeferMolOutput(), OBConversion::Read(), and OBMoleculeFormat::ReadChemObjectImpl().

ReadChemObject()

virtual bool ReadChemObject ( OBConversion *  )

inlinevirtualinherited

The "Convert" interface Read function.

Possibly reads multiple new objects on the heap and subjects them to its DoTransformations() function, which may delete them again. Sends result to pConv->AddChemObject()

Reimplemented in XMLMoleculeFormat, and OBMoleculeFormat.

Referenced by OBConversion::Convert().

WriteMolecule()

virtual bool WriteMolecule ( OBBase *  , OBConversion *    )

inlinevirtualinherited

The "API" interface Write function.

Writes a single object Does not delete the object; can be used with a pointer to an chem object on the heap or the stack.

Returns

false on error.

Referenced by OBMoleculeFormat::DeleteDeferredMols(), OBMoleculeFormat::DoOutputOptions(), OBMoleculeFormat::OutputDeferredMols(), OBConversion::Write(), and OBMoleculeFormat::WriteChemObjectImpl().

WriteChemObject()

virtual bool WriteChemObject ( OBConversion *  )

inlinevirtualinherited

The "Convert" interface Write function.

Writes a single object Deletes the object after writing

Returns

false on error

Reimplemented in XMLMoleculeFormat, and OBMoleculeFormat.

Referenced by OBConversion::AddChemObject(), and OBConversion::Convert().

Description()

virtual const char* Description ( )

pure virtualinherited

Information on this format. Printed out in response to -Hxxx option where xxx id the id of the format.

Must be provided by each format class. Can include a list of command line Options. These may be used to construction check boxes, radio buttons etc for GUI interface.

Reimplemented from OBPlugin.

Referenced by OBConversion::GetNextFormat(), and OBConversion::RegisterOptionParam().

TargetClassDescription()

const char * TargetClassDescription ( )

virtualinherited

A decription of the chemical object converted by this format.

If not provided, the object type used by the default format is used (usually OBMol).

Referenced by OBConversion::ReportNumberConverted().

GetType()

const type_info & GetType ( )

virtualinherited

Returns

the type of chemical object used by the format. Defaults to that used by the default format. Useful for checking that a format can handle a particular object.

Reimplemented in XMLMoleculeFormat, and OBMoleculeFormat.

SpecificationURL()

virtual const char* SpecificationURL ( )

inlinevirtualinherited

Web address where the format is defined.

GetMIMEType()

virtual const char* GetMIMEType ( )

inlinevirtualinherited

Chemical MIME type associated with this file type (if any)

Flags()

virtual unsigned int Flags ( )

inlinevirtualinherited

Decribes the capabilities of the format (Read only etc.)

Currently, can be a bitwise OR of any of the following NOTREADABLE READONEONLY NOTWRITABLE WRITEONEONLY DEFAULTFORMAT READBINARY WRITEBINARY READXML

Referenced by OBConversion::AddChemObject(), OBConversion::Convert(), OBMoleculeFormat::DeleteDeferredMols(), OBConversion::GetNextFormat(), OBMoleculeFormat::ReadChemObjectImpl(), OBConversion::SetInFormat(), OBConversion::SetInStream(), and OBConversion::SetOutFormat().

MakeNewInstance()

virtual OBFormat* MakeNewInstance ( )

inlinevirtualinherited

Returns

a pointer to a new instance of the format, or NULL if fails. Normally a single global instance is used but this may cause problems if there are member variables and the format is used in more than one place in the program.

RegisterFormat()

int RegisterFormat ( const char *  ID, const char *  MIME = NULL  )

inherited

Referenced by OBConversion::RegisterFormat().

Display()

bool Display ( std::string &  txt, const char *  param, const char *  ID = NULL  )

virtualinherited

Provides a description in txt of the format specified by itr. If param starts with "in", "read", "out" or "write" only the appropriate formats are output. The others return false. If param contains "verbose", the whole description is output.

Reimplemented from OBPlugin.

FormatFromMIME()

OBFormat * FormatFromMIME ( const char *  MIME )

staticinherited

Referenced by OBConversion::FormatFromMIME().
