Accessors

flags

• get flags(): CoreObjectFlags

Returns

CoreObjectFlags

Inherited from

Asset.flags

---

id

• get id(): string

Object's (unique) id

Note that the id of the object cannot be set (it is automatically assigned upon construction)

Returns

string

Inherited from

Asset.id

---

metaObject

• get metaObject(): undefined | MetaObject

Returns the MetaObject that describes this class

Returns

undefined | MetaObject

Inherited from

Asset.metaObject

---

name

• get name(): string

The object's name

The object's name is a free text value which defaults to an empty string.

Note that when the name of the object changes, the CoreObject.EVT_NAME_CHANGED signal will be emitted.

Returns

string

Inherited from

Asset.name

• set name(v): void

Parameters

Name	Type
v	string

Returns

void

Inherited from

Asset.name

---

url

• get url(): string

Returns

string

• set url(v): void

Parameters

Name	Type
v	string

Returns

void

Methods

deserialize

▸ deserialize(d): void

Parameters

Name	Type
d	any

Returns

void

Overrides

Asset.deserialize

---

getExtras

▸ getExtras(): any

Returns any extra data that this object needs to save during serialization.

In some cases an object might need to save some extra data without necessarily this extra data being part of its state (e.g. the AssetsLibrary of a Scene). In these cases subclasses can re-implement this method and return the data required.

The default implementation returns undefined meaning that no extra data needs to be saved during serialization.

Returns

any

Inherited from

Asset.getExtras

---

getState

▸ getState(minified?): any

Returns this object's state

The object's state is an object containing key/value pairs corresponding to this object's properties. For example:

{
    id: "Ssba4ch5ruok",
    name: "Circle",
    radius: 2,
   // ...
}

To avoid including properties that are currently in their default value you can set minified = true when calling getState.

Note that read-only properties are not part of the object's state (with the exception of the id)

Parameters

Name	Type	Default value	Description
minified	boolean	false	Whether to return a minified state or not

Returns

any

Inherited from

Asset.getState

---

getType

▸ getType(): AssetType

Returns

AssetType

Inherited from

Asset.getType

---

serialize

▸ serialize(): Object

Returns

Object

Name	Type
id	string
name	string
type	AssetType
url	string

Overrides

Asset.serialize

---

setExtras

▸ setExtras(_x): boolean

Sets any extra data that this object needs during de-serialization.

Returns true on success, otherwise returns false.

The default implementation does nothing and returns true.

Parameters

Name	Type
_x	any

Returns

boolean

Inherited from

Asset.setExtras

---

setFlag

▸ setFlag(flag, on?): void

Parameters

Name	Type	Default value
flag	CoreObjectFlags	undefined
on	boolean	true

Returns

void

Inherited from

Asset.setFlag

---

setState

▸ setState(state, updateId?): boolean

Sets the object's state

Parameters

Name	Type	Default value	Description
state	any	undefined	The state to be set
updateId	boolean	true	Whether to also update the id property

Returns

boolean

True on success otherwise false

Inherited from

Asset.setState

testFlag

▸ testFlag(flag): boolean

Parameters

Name	Type
flag	CoreObjectFlags

Returns

boolean
