id¶

   $id = $proxy->id

Returns the object ID for the "Tangence" object being proxied for.

classname¶

   $classname = $proxy->classname

Returns the name of the class of the "Tangence" object being proxied for.

class¶

   $class = $proxyobj->class

Returns the Tangence::Meta::Class object representing the class of this object.

can_method¶

   $method = $proxy->can_method( $name )

Returns the Tangence::Meta::Method object representing the named method, or "undef" if no such method exists.

can_event¶

   $event = $proxy->can_event( $name )

Returns the Tangence::Meta::Event object representing the named event, or "undef" if no such event exists.

can_property¶

   $property = $proxy->can_property( $name )

Returns the Tangence::Meta::Property object representing the named property, or "undef" if no such property exists.

call_method¶

   $result = $proxy->call_method( $mname, @args )->get

Calls the given method on the server object, passing in the given arguments. Returns a Future that will yield the method's result.

subscribe_event¶

   $proxy->subscribe_event( $event, %callbacks )->get

Subscribes to the given event on the server object, installing a callback function which will be invoked whenever the event is fired.

Takes the following named callbacks:

on_fire => CODE

Callback function to invoke whenever the event is fired

 $on_fire->( @args )
    

The returned "Future" it is guaranteed to be completed before any invocation of the "on_fire" event handler.

unsubscribe_event¶

   $proxy->unsubscribe_event( $event )

Removes an event subscription on the given event on the server object that was previously installed using "subscribe_event".

get_property¶

   $value = $proxy->get_property( $prop )->get

Requests the current value of the property from the server object.

get_property_element¶

   $value = $proxy->get_property_element( $property, $index_or_key )->get

Requests the current value of an element of the property from the server object.

prop¶

   $value = $proxy->prop( $property )

Returns the locally-cached value of a smashed property. If the named property is not a smashed property, an exception is thrown.

set_property¶

   $proxy->set_property( $prop, $value )->get

Sets the value of the property in the server object.

watch_property¶

   $proxy->watch_property( $property, %callbacks )->get

watch_property_with_initial¶

   $proxy->watch_property_with_initial( $property, %callbacks )->get

Watches the given property on the server object, installing callback functions which will be invoked whenever the property value changes. The latter form additionally ensures that the server will send the current value of the property as an initial update to the "on_set" event, atomically when it installs the update watches.

Takes the following named arguments:

on_updated => CODE

Optional. Callback function to invoke whenever the property value changes.

 $on_updated->( $new_value )
    

If not provided, then individual handlers for individual change types must be provided.

The set of callback functions that are required depends on the type of the property. These are documented in the "watch_property" method of Tangence::Object.

watch_property_with_cursor¶

   ( $cursor, $first_idx, $last_idx ) =
      $proxy->watch_property_with_cursor( $property, $from, %callbacks )->get

A variant of "watch_property" that installs a watch on the given property of the server object, and additionally returns an cursor object that can be used to lazily fetch the values stored in it.

The $from value indicates which end of the queue the cursor should start from; "CUSR_FIRST" to start at index 0, or "CUSR_LAST" to start at the highest-numbered index. The cursor is created atomically with installing the watch.

unwatch_property¶

   $proxy->unwatch_property( $property )

Removes a property watches on the given property on the server object that was previously installed using "watch_property".

next_forward¶

   ( $index, @more ) = $cursor->next_forward( $count )->get

next_backward¶

   ( $index, @more ) = $cursor->next_backward( $count )->get

Requests the next items from the cursor. "next_forward" moves forwards towards higher-numbered indices, and "next_backward" moves backwards towards lower-numbered indices. If $count is unspecified, a default of 1 will apply.

The returned future wil yield the index of the first element returned, and the new elements. Note that there may be fewer elements returned than were requested, if the end of the queue was reached. Specifically, there will be no new elements if the cursor is already at the end.
