Detailed Description

template<typename TVal, typename TCont = std::vector<TVal>>
class mup::Stack< TVal, TCont >

Parser stack implementation.

Stack implementation based on a std::stack. The behaviour of pop() had been slightly changed in order to get an error code if the stack is empty. The stack is used within the Parser both as a value stack and as an operator stack.

Member Function Documentation

pop()

template<typename TVal, typename TCont = std::vector<TVal>>

value_type mup::Stack< TVal, TCont >::pop ( )

inline

Pop a value from the stack.

Unlike the standard implementation this function will return the value that is going to be taken from the stack.

Exceptions

ParserException

in case the stack is empty.

Here is the call graph for this function:

push()

template<typename TVal, typename TCont = std::vector<TVal>>

void mup::Stack< TVal, TCont >::push ( const value_type & a_Val )

inline

Push an object into the stack.

Parameters

a_Val

object to push into the stack.

Exceptions

nothrow

top()

template<typename TVal, typename TCont = std::vector<TVal>>

value_type & mup::Stack< TVal, TCont >::top ( )

inline

Return reference to the top object in the stack.

The top object is the one pushed most recently.
