This interface exposes the general notion of a scheduled object with an integral priority value. Following UNIX conventions, smaller (and possibly negative) values have higher priority.

Last changed in Gecko 1.8 (Firefox 1.5 / Thunderbird 1.5 / SeaMonkey 1.0)This interface does not strictly define what happens when the priority
of an object is changed. An implementation of this interface is free to define the side-effects of changing the priority
of an object. In some cases, changing the priority
of an object may be disallowed (resulting in an exception being thrown) or may simply be ignored.
Method overview
void adjustPriority(in long delta); |
Attributes
Attribute | Type | Description |
priority | long | The object's priority. It can be modified to change the priority of the object. Typical priority values are defined in the idl file as PRIORITY_HIGHEST ... PRIORITY_LOWEST . The implementation is free to truncate a given priority value to whatever limits are appropriate. Typically this attribute is initialized to PRIORITY_NORMAL , but implementations may choose to assign a different initial value. |
