goog.structs.SimplePool

Provided By	`goog.structs.SimplePool`
Extends	`goog.Disposable`
All Implemented Interfaces	`goog.disposable.IDisposable`

A generic pool class. Simpler and more efficient than goog.structs.Pool because it doesn't maintain a list of objects that are in use. This class has constant overhead and doesn't create any additional objects as part of the pool management after construction time.

IMPORTANT: If the objects being pooled are arrays or maps that can have unlimited number of properties, they need to be cleaned before being returned to the pool.

Also note that goog.object.clean actually allocates an array to clean the object passed to it, so simply using this function would defy the purpose of using the pool.

new SimplePool`<T>`( `initialCount`, `maxCount` )

Parameters

`initialCount`	`number`
	Initial number of objects to populate the free pool at construction time.
`maxCount`	`number`
	Maximum number of objects to keep in the free pool.

Instance Methods

Invokes 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.

Defined by

goog.Disposable

Parameters

`callback`	`function(): ?`
	The callback function.
`opt_scope`	`(T\|null)=`
	An optional scope to call the callback in.

VIEW SOURCE

Should be overridden by sub-classes to return an instance of the object type that is expected in the pool.

Overrides

goog.structs.SimplePool

Parameters

None.

Returns

T

The created object.

VIEW SOURCE

Disposes of the object and its resources.

Overrides

goog.Disposable

Specified by

goog.disposable.IDisposable

Parameters

None.

Returns

Nothing.

VIEW SOURCE

Disposes of the pool and all objects currently held in the pool.

Overrides	`goog.structs.SimplePool`
Parameters	None.

VIEW SOURCE

Should be overrideen to dispose of an object. Default implementation is to remove all of the object's members, which should render it useless. Calls the object's dispose method, if available.
