Inheritance diagram for Qore::<closure>:

Public Member Methods
int	typeCode ()
	Returns Qore::NT_CLOSURE. More...
Public Member Methods inherited from <callref>
bool	callp ()
	Returns True because this is a callable type. More...
auto	exec (...)
	Evaluates the code with the arguments given and returns the result. More...
int	typeCode ()
	Returns Qore::NT_CALLREF. More...
bool	val ()
	Returns True. More...
Public Member Methods inherited from <value>
bool	callp ()
	Returns False; this method is reimplemented in other types and will return True if the given expression is a callable value (ie closures or call references) More...
bool	complexType ()
	returns True if the value has a complex type, False if not More...
bool	empty ()
	Returns True; this method will be reimplemented in container types where it may return False. More...
string	fullType (*bool with_namespaces)
	returns the full type name which differs from the simple type name in case of complex types and objects More...
bool	intp ()
	Returns False; this method is reimplemented in other types and will return True if the given expression can be converted to an integer. More...
AbstractIterator	iterator ()
	Returns an iterator object for the value; the default iterator object returned is SingleValueIterator. More...
int	lsize ()
	Returns 1; the return value of this method should give the list size of the value, which is normally 1 for non-lists (except for NOTHING where the size will be 0) and the number of the elements in the list for lists; this method will be reimplemented in other types where it may return other values. More...
int	size ()
	Returns zero; this method will be reimplemented in container types where it may return a non-zero value. More...
bool	sizep ()
	Returns True if the type can return a non-zero size (True for containers including binary objects and strings, False for everything else) More...
bool	strp ()
	Returns False; this method is reimplemented in other types and will return True if the given expression can be converted to a string. More...
bool	toBool ()
	Returns the boolean representation of the value; the default is False. More...
float	toFloat ()
	Returns the floating-point representation of the value; the default is 0.0. More...
int	toInt ()
	Returns the integer representation of the value; the default is 0. More...
number	toNumber ()
	Returns the arbitrary-precision numeric representation of the value; the default is 0. More...
string	toString ()
	Returns the string representation of the value; the default is an empty string. More...
string	type ()
	Returns the string type for the value. More...
int	typeCode ()
	Returns the type code for the value. More...
bool	val ()
	Returns False; this method is reimplemented in other types and will return True if the given expression has a non-empty value. More...
