Detailed Description

Interface for callback objects.

All Parser functions and operators must implement this interface.

Member Function Documentation

GetArgc()

int mup::ICallback::GetArgc

(

)

const

Returns the m´number of arguments required by this callback.

Returns

Number of arguments or -1 if the number of arguments is variable.

Here is the call graph for this function:

GetParent()

ParserXBase * mup::ICallback::GetParent ( )

protected

Returns a pointer to the parser object owning this callback.

Precondition

[assert] m_pParent must be defined

Here is the call graph for this function:

SetParent()

void mup::ICallback::SetParent

(

parent_type *

a_pParent

)

Assign a parser object to the callback.

Parameters

a_pParent

The parser that belongs to this callback object.

The parent object can be used in order to access internals of the parser from within a callback object. Thus enabling callbacks to delete variables or functions if this is desired.
