Detailed Description

The TypeRegistry registers faudes-types.

A faudes-type may be any class derived from faudes::Type, e.g. EventSet and generator. The registry maintains a mapping from faudes-type names to registred faudes::TypeDefinition. It provides an interface to inspect TypeDefinitions or to construct faudes-type objects by their type name.

Technical note: the class is implemented according to the "Singleton" design pattern, ie, only one global instance of the registry can exist.

void faudes::TypeRegistry::Clear ( void   )  [virtual]

Clear all registered type definitions.

This will also delete the correponsing prototype objects.

Definition at line 62 of file cfl_registry.cpp.

const TypeDefinition & faudes::TypeRegistry::Definition ( const Type rType  )  const

Look up the type definition by faudes object.

Techcal note: this implementation is slow, we should use a type id map.

Parameters:
rType Reference to faudes::Type to search for.
Returns:
Reference to faudes::TypeDefinition
Exceptions:
Exception 
  • Unknown type (id 46)

Definition at line 193 of file cfl_registry.cpp.

const TypeDefinition & faudes::TypeRegistry::Definition ( const std::string &  rTypeName  )  const

Look up the type definition by faudes-type name.

void faudes::TypeRegistry::DoWrite ( TokenWriter rTw,
const std::string &  rLabel = "",
const Type pContext = 0 
) const [protected, virtual]

Write registry data of this to TokenWriter.

Since the registry cannot reconfigure itself from a token stream, this output is informative only. However, MergeDocumentation will accept the format to extract documentation.

Parameters:
rTw Reference to TokenWriter
rLabel Label of section to write
pContext Write context to provide contextual information
Exceptions:
Exception 
  • IO errors (id 2)

Reimplemented from faudes::Type.

Definition at line 233 of file cfl_registry.cpp.

TypeRegistry::Iterator faudes::TypeRegistry::End ( void   )  const

STL interator to the internal type-name map.

Returns:
Iterator to the end of the map.

Definition at line 87 of file cfl_registry.cpp.

bool faudes::TypeRegistry::Exists ( const Type rType  )  const

Test existence of a faudes-type by faudes object.

Parameters:
rType Object of type to look up
Returns:
True, if a corresponding definition is registered.

Definition at line 227 of file cfl_registry.cpp.

bool faudes::TypeRegistry::Exists ( const std::string &  rName  )  const

Test existence of a faudes-type by its name.

Parameters:
rName Name of type to look up
Returns:

TypeRegistry * faudes::TypeRegistry::G ( void   )  [static]

Method to access the single global instance of the registry.

Definition at line 52 of file cfl_registry.cpp.

void faudes::TypeRegistry::Insert ( Type pProto,
const std::string &  rTypeName 
) [inline]

Register a faudes-type with specified type name.

This is a convenience function: it uses the specified object as a a prototype and registers it under the given name. The registry takes ownership of the prototype. However, no documentation is added. See also MergeDocumentation.

Parameters:
pProto Prototype object
rTypeName Specify the faudes-type name
Exceptions:
Exception 
  • Identical name found (id 46)

Definition at line 162 of file cfl_registry.h.

template<class T >
void faudes::TypeRegistry::Insert ( const std::string &  rTypeName = ""  )  [inline]

Register a faudes-type with specified type name.

This is a convenience function: it uses the template parameter to construct the new instance of TypeDefinition to be registered. However, no documentation is added. See also MergeDocumentation.

Template Parameters:
T Template parameter to specify c++ type to register
Parameters:
rTypeName Specify the faudes-type name
Exceptions:
Exception 
  • Identical name found (id 46)

Definition at line 141 of file cfl_registry.h.

void faudes::TypeRegistry::Insert ( TypeDefinition pTypeDef  ) 

Add another type definition to the registry.

The registry takes the ownership pf the provided type definition. It will be deleted either in Clear() or when the registry is destructed.

Exception 
  • Token mismatch (id 50, 51, 52)
  • IO Error (id 1)

Definition at line 143 of file cfl_registry.cpp.

void faudes::TypeRegistry::MergeDocumentation ( TokenReader rTr  ) 

Scan token input for type documentation.

This function scans the entire token stream for sections with label "TypeDefinition". Any such section that refers to a type name which is known to the registry, will be applied to the corresponding registry entry. Typical invokation is as follows

 TypeRegistry::G()->Insert<EventSet>("EventSet");
 TypeRegistry::G()->Insert<Generator>("Generator");
 TypeRegistry::G()->MergeDocumentation("alldocufile.rti");
Parameters:
rTr Token stream.
