Type parameters:

T

Parameters:

Name	Type
type	string
payload?	T

Returns: Message<T>

Inherited from: Pooled

Properties

objectInPool

• objectInPool: boolean= false

objectInPool is true if an object is made available in the object pool. If it is false it is not currently available in the object pool. This is used to avoid adding the same object to the same object pool multiple times if there are successive calls to free the the same object.

payload

• Optional payload: undefined | T

type

• type: string

Implementation of: IMessage.type

CLASS_SERIALIZATION_KEY

▪ Readonly Static CLASS_SERIALIZATION_KEY: jamjar.Message= "jamjar.Message"

---

pools

▪ Protected Static pools: Map<string, [number, IPoolable[]]>

pools is the global, static mapping of string keys to object pools. An object pool contains two pieces of data, the maximum size of the pool (first value), and the objects that make up the pool as an array (second value).

Inherited from: Pooled.pools

Methods

Free

▸ Free(): void

Free releases an object or it's constituent parts back into any available object pools.

Returns: void

Implementation of: IPoolable

---

Recycle

▸ Recycle(type: string, payload?: T): IPoolable

Parameters:

Name	Type
type	string
payload?	T

Returns: IPoolable

---

Serialize

▸ Serialize(): string

Returns: string

Implementation of: ISerializable

---

Deserialize

▸ StaticDeserialize(json: any): Message<unknown>

Parameters:

Name	Type
json	any

Returns: Message<unknown>

---

Free

▸ StaticFree<T>(obj: Message<T>): void

Free the provided Message.

Type parameters:

Name
T

Parameters:

Name	Type
obj	Message<T>

Returns: void

---

Init

▸ StaticInit(size: number): void

Initialize the Message pool to the size provided.

Parameters:

Name	Type
size	number

Returns: void

---

New

▸ StaticNew<T>(type: string, payload?: T): Message<T>

Create a Message.New, using pooling if available.

Type parameters:

Name
T

Parameters:

Name	Type
type	string
payload?	T

Returns: Message<T>

---

free

▸ Protected Staticfree(poolKey: string, obj: IPoolable): void

free is used to mark a provided object as free in the pool provided. This method can be called multiple times with the same object, it will only add one entry to the pool.

Parameters:

Name	Type	Description
poolKey	string	The key of the pool to add the object to.
obj	IPoolable	The object to add to the pool.

Returns: void

Inherited from: Pooled

---

init

▸ Protected Staticinit(poolKey: string, emptyGenerator: () => IPoolable, size: number): void

init is used to initialize an object pool to a certain size. This method takes a key of the pool to initialize, an 'empty generator' which is a function that should return an empty/blank instance of the object being pooled which can be overwritten at a later point, and the maximum size of the pool (which it will be initialized to at the start using the empty generator).

Parameters:

Name	Type
poolKey	string
emptyGenerator	() => IPoolable
size	number

Returns: void

Inherited from: Pooled

---

new

▸ Protected Staticnew(poolKey: *string*, type: (...args: *any*) => T, ...args: any): T

new is used to request a new object from the pool specified, if the pool is unavailable or empty it will use the type to provision a new object through a constructor. This is a generic method, it includes a cast to the generic type provided - this cast can fail if the objects returned from the pool are not the type expected.

Type parameters:

Name	Type
T	IPoolable

Parameters:

Name	Type	Description
poolKey	string	The key of the pool to retrieve from.
type	(...args: any) => T	The fallback constructor to use if the pool is not initialized/empty.
...args	any	The args to use when creating/recycling the object.

Returns: T
