Detailed Description

The FunctionRegistry registers faudes-functions. A faudes-functions operates on faudes objects, eg the parallel composition of two generators is available as faudes-function. The registry maintains a mapping between function names and a coresponding function::Definition. The latter provides signatures, ie parameter types the function can take. The registry provides an interface to inspect TypeDefinitions or to construct function 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::FunctionRegistry::Clear ( void )

virtual

Clear all registered function definitions. This will also delete the correponsing prototype objects.

Definition at line 406 of file cfl_registry.cpp.

◆ Definition() [1/2]

const FunctionDefinition & faudes::FunctionRegistry::Definition ( const Function & rFunction ) const

Look up the function definition by faudes object

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

Parameters

rFunction Reference to faudes::Function to search for.

Returns: Reference to faudes::FunctionDefinition

Exceptions

Exception

Unknown function (id 46)

Definition at line 550 of file cfl_registry.cpp.

◆ Definition() [2/2]

const FunctionDefinition & faudes::FunctionRegistry::Definition ( const std::string & rFunctionName ) const

Look up the function definition by faudes-function name

Parameters

rFunctionName Label of faudes::FunctionDefinition to search for.

Returns: Reference to faudes::FunctionDefinition

Exceptions

Exception

Unknown function (id 46)

Definition at line 538 of file cfl_registry.cpp.

◆ DoWrite()

void faudes::FunctionRegistry::DoWrite	(	TokenWriter &	rTw,
		const std::string &	rLabel = `""`,
		const Type *	pContext = `0`
	)		const

protectedvirtual

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 insert/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 582 of file cfl_registry.cpp.

◆ End()

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

STL interator to the internal function-name map.

Returns: Iterator to the end of the map.

Definition at line 433 of file cfl_registry.cpp.

◆ Exists() [1/2]

bool faudes::FunctionRegistry::Exists ( const Function & rFunction ) const

Test existence of a faudes-function by faudes object

Parameters

rFunction Object of function to look up

Returns: True, if a corresponding definition is registered.

Definition at line 576 of file cfl_registry.cpp.

◆ Exists() [2/2]

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

Test existence of a faudes-function by its name.

Parameters

rName Name of function to look up

Returns: True, if a corresponding definition is registered.

Definition at line 571 of file cfl_registry.cpp.

◆ FunctionName()

const std::string & faudes::FunctionRegistry::FunctionName ( const Function & rFunction ) const

Look up the function name by faudes object

Parameters

rFunction Reference to faudes::Function to search for.

Returns: Function name as string or "" if unknown.

Definition at line 561 of file cfl_registry.cpp.

◆ G()

FunctionRegistry * faudes::FunctionRegistry::G ( )

static

Method to access the single global instance of the registry.

Definition at line 396 of file cfl_registry.cpp.

◆ Insert() [1/2]

template<class T >

void faudes::FunctionRegistry::Insert ( const std::string & rFunctionName = "" )

inline

Register a faudes-function with specified function name.

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

Template Parameters

T	Template parameter to specify c++ function to register

Parameters

rFunctionName Specify the faudes-function name

Exceptions

Exception

Identical name found (id 46)

Definition at line 594 of file cfl_registry.h.

◆ Insert() [2/2]

void faudes::FunctionRegistry::Insert ( FunctionDefinition * pFunctionDef )

Add another function definition to the registry.

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

Parameters

pFunctionDef Function definition to insert

Exceptions

Exception

Identical name found (id 46)

Definition at line 438 of file cfl_registry.cpp.

◆ MergeDocumentation() [1/2]

void faudes::FunctionRegistry::MergeDocumentation ( const std::string & rFileName )

Scan file for function documentation. Convenience method, see also MergeDocumentation(TokenReader& rTr)

Parameters

rFileName Name of file to scan.

Exceptions

Exception

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

Definition at line 500 of file cfl_registry.cpp.

◆ MergeDocumentation() [2/2]

void faudes::FunctionRegistry::MergeDocumentation ( TokenReader & rTr )

Scan token input for function documentation. This function scans the entire token stream for sections with label "FunctionDefinition". Any such section that refers to a function name which is known to the registry, will be applied to the corresponding registry entry.

Parameters

rTr	Token stream.

Exceptions

Exception

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

Definition at line 467 of file cfl_registry.cpp.

◆ NewFunction() [1/2]

Function * faudes::FunctionRegistry::NewFunction ( const Function & rFunction ) const

Construct a faudes object by protofunction object.

Depreciated: use new on the faudes object instead.

Parameters

rFunction Protofunction object.

Returns: Pointer to new faudes::Function instance

Exceptions

Exception

Unknown function (id 47)

Definition at line 525 of file cfl_registry.cpp.

◆ NewFunction() [2/2]

Function * faudes::FunctionRegistry::NewFunction ( const std::string & rFunctionName ) const

Construct a faudes object by function name

Uses the internal prototype object to construct an object of the same c function on the heap.

Parameters

rFunctionName Label of FunctionDefinition to search for.

Returns: Pointer to new faudes::Function instance

Exceptions

Exception

Unknown function (id 47)

Definition at line 507 of file cfl_registry.cpp.

◆ operator=()

Type & faudes::Type::operator=

Assign configurationdata from other object. Derived classes should implement the operator form for the assignment for each source type which allows for a non-trivial assignment. This includes the particular case were the source and destination types match exactly. In the latter case the DoAssign method should be invoked. In contrast to the Assign function, the operator form must not be reimplemented for missmatched source types: the operator form only accepts sensible source types. This allows for compiletime typeckecking. However, the downside is that when the type is not known at compiletime, configuration is not properly assigned.

Re-implementation can be done via the convenience macros FAUDES_TYPE_DECLARATION and FAUDES_TYPE_IMPLEMENTATION.

Parameters

rSrc	Source to copy from

Returns: Reference to this object.

Definition at line 340 of file cfl_types.cpp.

◆ Size()

int faudes::FunctionRegistry::Size ( void ) const

Return number of registered function definitions.

Returns: Size of map.

Definition at line 423 of file cfl_registry.cpp.
