Detailed Description

A decoration element is an element without any math meaning, which is used only for GUI input.

Definition at line 214 of file Decoration.h.

Public Member Functions

bool data_isValidContainerFor (mcElementType t) const
 Returns TRUE if this element can safely contain the given element type.

Private Member Functions

 mcDEFINE_ABSTRACT_CLASS (Decoration, mcElement)

Member Function Documentation

bool mcDecoration::data_isValidContainerFor (  mcElementType  t  )  const [inline, virtual]
 

Returns TRUE if this element can safely contain the given element type.

Without this function a lot of errors could be undetectable:

        mcPolynomial pol; // creates a new polynomial
        mcElement e(pol); // references it
        [...]    // the programmers forgots what "e" references
        mcFraction f(e);  // mcFraction wraps a mcPolynomialHelpers class !
        f.data_GetNum();  // CRASH

This function must be overridden by mcElement-derived classes in order to provide a list of the mcElementType it can safely contain.

Reimplemented from mcElement.

Reimplemented in mcAddSubOp, mcEmptyBox, mcMultDivOp, mcOperator, mcParenthesis, and mcText.

Definition at line 220 of file Decoration.h.
