nsISupportsPriority in Firefox 1.5

Implemented by

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

 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.

Constants

 Typical priority values.

const long PRIORITY_HIGHEST = -20

const long PRIORITY_HIGH = -10

const long PRIORITY_NORMAL = 0

const long PRIORITY_LOW = 10

const long PRIORITY_LOWEST = 20

Attributes

 This attribute may be modified to change the priority of this object.  The
 implementation of this interface 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.

attribute long priority

Methods

 This method adjusts the priority attribute by a given delta.  It helps
 reduce the amount of coding required to increment or decrement the value
 of the priority attribute.
