◆ 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
objthe object to use for the call
methodthe 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-EXISTThe named method does not exist in this class
ILLEGAL-EXPLICIT-METHOD-CALLThe named method may not be called explicitly
METHOD-IS-PRIVATEThe named method is private and therefore can only be called within the class
BASE-CLASS-IS-PRIVATEThe 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,
__7_ softlist< auto varg 
)

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

Parameters
objthe object to use for the call
methodthe method to call
vargany 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-EXISTThe named method does not exist in this class
ILLEGAL-EXPLICIT-METHOD-CALLThe named method may not be called explicitly
METHOD-IS-PRIVATEThe named method is private and therefore can only be called within the class

◆ call_pseudo()

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

calls a pseudo-method on the given value

Parameters
valthe value to call the pseudo-method on
meththe 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,
__7_ softlist< auto argv 
)

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

Parameters
valthe value to call the pseudo-method on
meththe string method name of the pseudo-method to call
argvany 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()

METHOD-IS-PRIVATEThe named method is private and therefore can only be called within the class
BASE-CLASS-IS-PRIVATEThe named method is a member of a privately inherited base class
