## Detailed Description

Registration class. Stores a function pointer (returning a double).

Objects of this class are usually created via the Define_Function() macro.

## Constructor & Destructor Documentation

cFunctionType::cFunctionType ( | const cFunctionType & ft )`[inline]`

| Copy constructor.

cFunctionType::cFunctionType ( | const char * name,
| MathFuncNoArg f,
| int argc = -1 )

| Constructor.

cFunctionType::cFunctionType ( | const char * name,
| MathFunc1Arg f,
| int argc = -1 )

| Constructor.

cFunctionType::cFunctionType ( | const char * name,
| MathFunc2Args f,
| int argc = -1 )

| Constructor.

cFunctionType::cFunctionType ( | const char * name,
| MathFunc3Args f,
| int argc = -1 )

| Constructor.

cFunctionType::cFunctionType ( | const char * name,
| MathFunc4Args f,
| int argc = -1 )

| Constructor.

cFunctionType::~cFunctionType ( | )`[inline, virtual]`

| Destructor.

## Member Function Documentation

int cFunctionType::argCount ( | )`[inline]`

| Argument count to function.

cObject * cFunctionType::dup ( | ) const`[inline, virtual]`

| Creates and returns an exact copy of this object. See cObject for more details. Reimplemented from cObject.

MathFunc cFunctionType::mathFunc ( | )`[inline]`

| Returns function pointer as double function with unchecked arg list (no type safety!)

MathFunc1Arg cFunctionType::mathFunc1Arg ( | )

| Returns function pointer as double function with 1 double arg. Throws exception is actual arg count is different.

MathFunc2Args cFunctionType::mathFunc2Args ( | )

| Returns function pointer as double function with 2 double args. Throws exception is actual arg count is different.

MathFunc3Args cFunctionType::mathFunc3Args ( | )

| Returns function pointer as double function with 3 double args. Throws exception is actual arg count is different.

MathFunc4Args cFunctionType::mathFunc4Args ( | )

| Returns function pointer as double function with 4 double args. Throws exception is actual arg count is different.

MathFuncNoArg cFunctionType::mathFuncNoArg ( | )

| Returns function pointer as double function with no args. Throws exception is actual arg count is different.

cFunctionType & cFunctionType::operator= ( | const cFunctionType & )`[inline]`

| Assignment is not supported by this class: this method throws a cException when called.
