IObject

IObject is the parent interface of all interfaces and is the interface automatically implemented by all Class.

as

pub fn as(self: I, comptime T: type) t: {
    break :t if (isInterface(T)) ?T else ?*T;
}

Function: Dynamically convert object types

parameter:

• self: the interface instance you want to convert
• T: the type you want to convert to, which can be Class or Interface

Return: If the conversion is possible, return the converted object or interface, otherwise return null

Note

This conversion requires an array search operation, which is expensive.

asptr

pub fn asptr(self: I) *anyopaque

Function: Get rootptr

parameter:

• self: target interface instance

Returns: rootptr of self

asraw

pub fn asraw(self: I) IRaw

Function: Copy self.ptr and self.vptr to IRaw

parameter:

• self: sourceInterface

Returns: An IRaw with the values ​​of self.ptr and self.vptr copied

asraw is equivalent to the following code

pub fn asraw(self: I) IRaw {
    return IRaw{.ptr = self.ptr, .vptr = @ptrCast(self.vptr)};
}

eql

pub fn eql(self: I, other: I) bool

Function: Compare whether two interface instances are equal

parameter:

• self: one of the interfaces involved in the comparison
• other: another interface

Returns: true if equal, false otherwise

destroy

pub fn destroy(self: I) void

Function: Same as Class.destroy()
