EXT_CLASS

The EXT_CLASS constant specifies the name of the C++ class that represents the EngExtCpp extension library.

#ifndef EXT_CLASS
#define EXT_CLASS Extension
#endif

Comments

The default value of EXT_CLASS is Extension. You can change this value by defining EXT_CLASS before you include the header file Engextcpp.hpp.

Each extension command in the library is declared as a member of the class EXT_CLASS using the macro EXT_COMMAND_METHOD. For example, a library with two extension commands, extcmd and anotherextcmd, could define the class EXT_CLASS as follows:

class EXT_CLASS : public ExtExtension
{
public:
    EXT_COMMAND_METHOD(extcmd);
    EXT_COMMAND_METHOD(anotherextcmd);
}

Extension commands that have been declared by using EXT_COMMAND_METHOD should be defined by using EXT_COMMAND and should be exported from the library.

The EXT_DECLARE_GLOBALS macro creates a single instance of the EXT_CLASS class.

Requirements

Headers: Defined in Engextcpp.hpp. Include Engextcpp.hpp.
