Detailed Description

A Callable object.

Callable objects have an invoke() member function.

Definition at line 50 of file callable.h.

Member Function Documentation

◆ invoke() [1/3]

bool OGF::Callable::invoke ( )
inline

Invokes a method by method name.

This variant of invoke() is for methods with no argument and void return type.

Return values
trueif the method could be sucessfully invoked
falseotherwise

Definition at line 92 of file callable.h.

◆ invoke() [2/3]

bool OGF::Callable::invoke ( const ArgList args)
inline

Invokes a method by method name and argument list.

This variant of invoke() ignores the return value.

Parameters
[in]argsa const reference to the ArgList
Return values
trueif the method could be sucessfully invoked
falseotherwise

Definition at line 80 of file callable.h.

◆ invoke() [3/3]

virtual bool OGF::Callable::invoke ( const ArgList args,
Any ret_val 
)
pure virtual

Invokes a method with an argument list, and gets the return value.

Parameters
[in]argsa const reference to the ArgList
[out]ret_valthe return value as an Any
Return values
trueif the method could be sucessfully invoked
falseotherwise

Implemented in OGF::Request, OGF::LuaCallable, and OGF::Connection.
