Member Function Documentation

proc_service_index()

int Services_entry::proc_service_index

(

Proxy_info *

proc

)

find address of service in services that is offered by proc, if any. Note that if proc is the local process (o2_ctx->proc), the result can be an OSC or BRIDGE node, since these are proxies for the local process.

service_find()

O2node * Services_entry::service_find ( const char *  service_name, Services_entry **  services  )

static

Use initial part of an O2 address to find an o2_service using a hash table lookup.

Parameters

name	points to the service name (do not include the initial '!' or '/' from the O2 address).

Returns

The pointer to the service, which is a Hash_node, Handler_node, or Proxy_info (Proc_info, OSC_info or Bridge_info)

service_provider_replace()

O2err Services_entry::service_provider_replace ( const char *  service_name, O2node **  node_ptr, O2node *  new_service  )

static

replace the service named service_name offered by proc with new_service. This happens when we change from all-service handler to per-node handlers or vice versa. Also happens when we delete a service, and when we remove a remote service when it disconnects.

precondition: service_name does not have '/' && new_service != NULL

CASE 1: called from o2_method_new(), installing a global handler for service, maybe replacing an existing one, maybe not. CASE 2: called from o2_method_new(), replacing a global handler with a hash_node where we can install a Hash_node based on the next node in the address. (no more cases because we moved others to o2_service_remove)

show()

void Services_entry::show ( int  indent )

virtual

Reimplemented from O2node.
