Function Documentation

call_object_method()

auto Qore::call_object_method	(	object	obj,
		string	method,
			...
	)

Calls a method of an object, passing the remainder of the arguments to the function as arguments to the method.

Parameters

obj	the object to use for the call
method	the method to call
...	any additional arguments to the method

Returns

the value returned by the method call

Example:

auto result = call_object_method(obj, "method", arg1, arg2);

Exceptions

METHOD-DOES-NOT-EXIST	The named method does not exist in this class
ILLEGAL-EXPLICIT-METHOD-CALL	The named method may not be called explicitly
METHOD-IS-PRIVATE	The named method is private and therefore can only be called within the class
BASE-CLASS-IS-PRIVATE	The named method is a member of a privately inherited base class

Note

the method called could cause additional exceptions to be thrown

Since

Qore 0.8.12 as a replacement for deprecated camel-case callObjectMethod()

call_object_method_args()

auto Qore::call_object_method_args	(	object	obj,
		string	method,
		*softlist< auto >	varg
	)

Calls a method of an object, using the optional third argument as the argument list to the method.

Parameters

obj	the object to use for the call
method	the method to call
varg	any additional arguments to the method

Returns

the value returned by the method call

Example:

auto result = call_object_method_args(obj, "method", arglist);

Exceptions

METHOD-DOES-NOT-EXIST	The named method does not exist in this class
ILLEGAL-EXPLICIT-METHOD-CALL	The named method may not be called explicitly
METHOD-IS-PRIVATE	The named method is private and therefore can only be called within the class
BASE-CLASS-IS-PRIVATE	The named method is a member of a privately inherited base class

Note

the method called could cause additional exceptions to be thrown

call_pseudo()

auto Qore::call_pseudo	(	any	val,
		string	meth,
			...
	)

calls a pseudo-method on the given value

Parameters

val	the value to call the pseudo-method on
meth	the string method name of the pseudo-method to call
...	any other arguments to the method

Returns

the return value of the pseudo-method

See also

<value> for the class hierarchy of pseudo-classes

Note

this function can be used for security to ensure that a given pseudo-method of the <object> class is called, as by default if a method of the same name is implemented by the object's class, the class method will be called instead.

Since

Qore 0.8.5

call_pseudo_args()

auto Qore::call_pseudo_args	(	any	val,
		string	meth,
		*softlist< auto >	argv
	)

calls a pseudo-method on the given value with arguments given as a list

Parameters

val	the value to call the pseudo-method on
meth	the string method name of the pseudo-method to call
argv	any other arguments to the method

Returns

the return value of the pseudo-method

See also

<value> for the class hierarchy of pseudo-classes

Note

this function can be used for security to ensure that a given pseudo-method of the <object> class is called, as by default if a method of the same name is implemented by the object's class, the class method will be called instead.

Since

Qore 0.8.8

call_static_method()

auto Qore::call_static_method	(	string	class_name,
		string	method,
			...
	)

Calls a static method of an object, passing the arguments to the function as arguments to the method.

Example:

auto result = call_static_method("Namespace::Class::method", arg1, arg2);

Parameters

class_name	the with an optional namespace prefix
method	the static method to call
call_args	any additional arguments to the method

Returns

the value returned by the method call

Exceptions
