Detailed Description

A provider that provider chase intensisties to a running chase.

Not to be confused with a channel provider. The purpose of a Chase Intensity Provider is so that multiple entities (e.g. a cue, a scene & a direct fader) can run a chase simulatiously whilst maintinaing synronised chase timing.

IMPORTANT: Its posisble to end up with a memory retention deadlock (i.e objects will not get deallocated) because the provider adds itself to the chase (which retains the provider) and the provider retains the chase.

You must therfore make sure you call remove before you peroform the last release on the object.

Member Function Documentation

- (BOOL) autoOn

Does the chase get started when the provider sets an intensity value greater than zero? If set the chase will also automatically stop when the intensity it set to zero.

In both cases this only happens if no other provider is setting a value for the chase.

See also:

- setAutoOn:

- (LOChase *) chase

Get the chase this Intenity provider is using.

- (id) delegate

Get the current delegate.

Returns:

The delegate object

See also:

- setDelegate:

NSObject(LOChaseIntensityMasterDelegate) in LOChaseIntensityProvider.h

- (id) initWithChase:

(LOChase *)

theChase

Initilise the provider ready to be used.

This method registeres the provider with the chase.

Intensity is set to 0 on initilisation

IMPORTANT: To stop a memory retention deadlock make sure you call remove

Returns:

The initilised provider

See also:

- setIntensity:

- remove

- (void) remove

Remove ourself as a provider from a chase.

Its posisble to end up with a memory retention deadlock (i.e objects will not get deallocated) because the provider adds itself to the chase (which retains the provider) and the provider retains the chase.

You must therfore make sure you call remove before you peroform the last release on the object.

- (void) setAutoOn:

(BOOL)

flag

Set the autoOn mode.

See also:

- autoOn

- (void) setDelegate:

(id)

aDelegate

Set a new delegate object.

Parameters:

aDelegate

The object to receive all delegate messages

See also:

delegate:

NSObject(LOChaseIntensityMasterDelegate) in LOChaseIntensityProvider.h

- (void) setIntensity:

(unsigned char)

theIntensity

Set the intensity of the chase.

This function notifies the chase that there is a possible update for the output.

Parameters:

theIntensity

The intensity value
