Detailed Description

The variable class represents a parser variable.

This class stores a pointer to a value object and refers all operations to this value object.

Constructor & Destructor Documentation

◆ Variable()

mup::Variable::Variable ( IValue * pVal )

Create a variable and bind a value to it.

Parameters

pVal	Pointer of the value to bind to this variable.

It is possible to create an empty variable object by setting pVal to nullptr. Such variable objects must be bound later in order to be of any use. The parser does NOT assume ownership over the pointer!

Here is the call graph for this function:

Member Function Documentation

◆ GetPtr()

IValue * mup::Variable::GetPtr ( ) const

Returns the Value pointer bound to this variable.

Exceptions

nothrow

◆ GetType()

char_type mup::Variable::GetType ( ) const

virtual

Returns a character representing the type of the variable.

Exceptions

nothrow

Implements mup::IValue.

◆ operator=()

IValue & mup::Variable::operator= ( const Value & ref )
