Class: Schema
Represents a schema manager for block flavours and their relationships. Provides methods to register, validate, and query block schemas.
Properties
flavourSchemaMap
readonlyflavourSchemaMap:Map<string, {model: {children?:string[];flavour:string;isFlatData?:boolean;parent?:string[];props?: (...args) =>Record<string,any>;role:string;toModel?: (...args) =>BlockModel<object>; };transformer?: (...args) =>BaseBlockTransformer<object>;version:number; }>
A map storing block flavour names to their corresponding schema definitions.
Accessors
versions
Get Signature
get versions():
object
Returns an object mapping each registered flavour to its version number.
Returns
object
Methods
get()
get(
flavour): {model: {children?:string[];flavour:string;isFlatData?:boolean;parent?:string[];props?: (...args) =>Record<string,any>;role:string;toModel?: (...args) =>BlockModel<object>; };transformer?: (...args) =>BaseBlockTransformer<object>;version:number; } |undefined
Retrieves the schema for a given block flavour.
Parameters
flavour
string
The block flavour name.
Returns
{ model: { children?: string[]; flavour: string; isFlatData?: boolean; parent?: string[]; props?: (...args) => Record<string, any>; role: string; toModel?: (...args) => BlockModel<object>; }; transformer?: (...args) => BaseBlockTransformer<object>; version: number; } | undefined
The corresponding BlockSchemaType or undefined if not found.
isValid()
isValid(
child,parent):boolean
Checks if the child flavour is valid under the parent flavour.
Parameters
child
string
The child block flavour name.
parent
string
The parent block flavour name.
Returns
boolean
True if the relationship is valid, false otherwise.
register()
register(
blockSchema):Schema
Registers an array of block schemas into the schema manager.
Parameters
blockSchema
object[]
An array of block schema definitions to register.
Returns
Schema
The Schema instance (for chaining).
safeValidate()
safeValidate(
flavour,parentFlavour?,childFlavours?):boolean
Safely validates the schema relationship for a given flavour, parent, and children. Returns true if valid, false otherwise (does not throw).
Parameters
flavour
string
The block flavour to validate.
parentFlavour?
string
The parent block flavour (optional).
childFlavours?
string[]
The child block flavours (optional).
Returns
boolean
True if the schema relationship is valid, false otherwise.
toJSON()
toJSON():
object
Serializes the schema map to a plain object for JSON output.
Returns
object
An object mapping each flavour to its role, parent, and children.
validate()
validate(
flavour,parentFlavour?,childFlavours?):void
Validates the schema relationship for a given flavour, parent, and children. Throws SchemaValidateError if invalid.
Parameters
flavour
string
The block flavour to validate.
parentFlavour?
string
The parent block flavour (optional).
childFlavours?
string[]
The child block flavours (optional).
Returns
void
Throws
If the schema relationship is invalid.
validateSchema()
validateSchema(
child,parent):void
Validates the relationship between a child and parent schema. Throws if the relationship is invalid.
Parameters
child
The child block schema.
