Class PropertyModel<T>Abstract

This is the base class for fields and attributes, both of which define subvalues of logical structs.

Type Parameters

Constructors

Properties

asOf?: `${number}.${number}`
byteSize?: ByteSize

Applies to numeric types.

default?: FieldValue

The default value for the element.

description?: string
details?: string
errors?: DefinitionError[]
id?: number
isSeed?: boolean
isType?: boolean = true

Indicates that an element defines a datatype.

isTypeScope?: boolean

Indicates that an element may have type definitions as children.

metatype?: Metatype
name: string
operationalBase?: Model<BaseElement>

Normally base performs lookup based on type. If instead a model is installed it is used as the base.

The operational base also enables resolution from the operational base's tree. This enables resolution on operational models that are not installed in a parent hierarchy.

type?: string
until?: `${number}.${number}`
types: {
    [type: string]: (new (definition: any) => Model);
} = ...

Factory support. Populated by derivatives upon definition.

Accessors

  • get discriminator(): undefined | string
  • Obtain a discriminator that differentiates different models with the same name

    Returns undefined | string

  • get effectiveDefault(): any
  • The value to use as a default. The "default" field has a manually supplied value but this property decodes the default and/or generates a default from subfields.

    Returns any

  • get effectiveId(): undefined | number
  • Allows subclasses to pull a working ID from an alternate source.

    Returns undefined | number

  • get fields(): {
        [k: string]: T;
    }
  • Active members keyed by property name.

    Returns {
        [k: string]: T;
    }

    • [k: string]: T
  • get key(): undefined | string
  • Get a string that uniquely identifies this model. This is normally the effective ID but some models require a generated identifier.

    Returns undefined | string

  • get overridesShadow(): undefined | true
  • Determine whether this element overrides key properties of its shadow.

    Returns undefined | true

  • get path(): string
  • The path ("." delimited) in the Matter tree.

    This is informational and generally tries to adhere to JS API conventions.

    Returns string

Methods

  • Freeze the model hierarchy rooted at this model.

    When using a model as operational schema we implement various optimizations that assume the schema is immutable. This function enforces that assumption.

    To make changes to a frozen model use clone.

    Returns void
