◆ ADJ_DELEGATE_LAST

#define ADJ_DELEGATE_LAST   (ADJ_DELEGATE_MIDCHAIN)

Definition at line 45 of file adj_delegate.h.

Typedef Documentation

◆ adj_delegate_adj_deleted_t

typedef void(* adj_delegate_adj_deleted_t) (adj_delegate_t *aed)

Indication that the adjacency has been deleted.

The delegate provider should free the delegate.

Definition at line 73 of file adj_delegate.h.

◆ adj_delegate_format_t

typedef u8*(* adj_delegate_format_t) (const adj_delegate_t *aed, u8 *s)

Format function for the delegate.

Definition at line 78 of file adj_delegate.h.

◆ adj_delegate_t

Adj delegate.

This object is attached to the adjacency.

◆ adj_delegate_type_t

A Delagate is a means to implement the Delagation design pattern; the extension of an object's functionality through the composition of, and delgation to, other objects.

These 'other' objects are delegates. Delagates are thus attached to ADJ objects to extend their functionality. Built-in delegate types. When adding new types, if your code is within the vnet subsystem, then add a new type here. If not then use the adj_delegate_register_new_type API to register a new type.

◆ adj_delegate_vft_t

An ADJ delegate virtual function table.
