OperatorOnFunction &operator=(const OperatorOnFunction&)#

full copy of members

assign operator (full copy)

void print(std::ostream&) const#: print on stream attributes

inline void setX(const Point &P) const#: set X point (usefull for Kernel)

inline StrucType &strucType()#: return the operator returned structure

inline StrucType strucType() const#: return the operator returned structure

inline bool tangentRequired() const#: true if normal involved

inline ValueType &valueType()#: return the operator returned type

inline ValueType valueType() const#: return the operator returned type

Public Members

mutable bool conjugate_#: true if it has to be conjugated

Extension *ext_p#: extension operator to apply to

bool in_ext#: if true interpreted as ext(difop(f)) else interpreted as difop(ext(f)); default is true

mutable bool transpose_#: true if it has to be transposed

Friends

friend bool operator!=(const OperatorOnFunction&, const OperatorOnFunction&)#: different operator on function

friend bool operator==(const OperatorOnFunction&, const OperatorOnFunction&)#: same operator on function
