Instance Methods
this.addFreeObject( obj ) → void
voidAdds an object to the collection of objects that are free. If the object can not be added, then it is disposed.
NOTE: This method does not remove the object from the in use collection.

| Parameters |
|
this.addOnDisposeCallback<T>( callback, opt_scope ) → void
voidInvokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added. If a callback is added to an already disposed Disposable, it will be called immediately.

| Parameters |
|
this.adjustForMinMax() → void
voidAdjusts the objects held in the pool to be within the min/max constraints.
NOTE: It is possible that the number of objects in the pool will still be greater than the maximum count of objects allowed. This will be the case if no more free objects can be disposed of to get below the minimum count (i.e., all objects are in use).

| Parameters | None. |
this.contains( obj ) → boolean
booleanReturns true if the given object is in the pool.

dispose() method, if available.

this.setDelay( delay ) → void
voidSets the minimum delay between objects being returned by getObject, in milliseconds. This defaults to zero, meaning that no minimum delay is enforced and objects may be used as soon as they're available.

Instance Properties
this.creationStack → (string|undefined)
(string|undefined)If monitoring the goog.Disposable instances is enabled, stores the creation stack trace of the Disposable instance.
this.delay → number
numberThe minimum delay between objects being made available, in milliseconds. If this is 0, no minimum delay is enforced.
this.lastAccess → (number|null)
(number|null)The time of the last object being made available, in milliseconds since the epoch (i.e., the result of Date#toTime). If this is null, no access has occurred yet.
