Constructor & Destructor Documentation

Function() [1/3]

LLU::WS::Function::Function ( )

inline

Default constructor.

The head is empty and number of arguments is set to a dummy value. This constructor should only be used to create a Function right before calling WSStream::operator>> on it, which will read a function from top-level.

Function() [2/3]

LLU::WS::Function::Function ( const std::string &  h )

inlineexplicit

Create a Function with given head but unknown number of arguments.

You can later call WSStream::operator>> on such constructed Function to populate argument count with a value read from top-level.

Parameters

h	- function head

Function() [3/3]

LLU::WS::Function::Function ( const std::string &  h, int  argCount  )

inline

Construct a Function with given head and number of arguments.

Parameters

h	- function head
argCount	- number of arguments this function takes

Member Function Documentation

getArgc()

int LLU::WS::Function::getArgc

(

)

const

Get argument count.

Returns

number of arguments this function takes

getHead()

const std::string & LLU::WS::Symbol::getHead ( ) const

inherited

Get Symbol name/head.

Returns

head

setArgc()

void LLU::WS::Function::setArgc

(

int

newArgc

)

Set argument count.

Parameters

newArgc

- new value for argument count

setHead()

void LLU::WS::Symbol::setHead ( std::string  h )

inherited

Set Symbol name/head.

Parameters

h	- new head for the Symbol
