The source data object for this DataModel instance. Once constructed, the source object is sealed such that no keys may be added nor removed.
An immutable reverse-reference to a parent DataModel to which this model belongs.
Is the current state of the DataModel valid?
The defined and cached Data Schema for all instances of this DataModel.
Define the data schema for this document instance.
Is the current state of this DataModel invalid?
Define the data schema for documents of this type.
Reset the state of this data instance back to mirror the contained source data, erasing any changes.
Clone a model, creating a new data model by combining current data with provided overrides.
The cloned Document instance
Validate the data contained in the document to check for type and content This function throws an error if data within the document is not valid
Optional parameters which customize how validation occurs.
An indicator for whether the document contains valid data
Update the DataModel locally by applying an object of changes to its source data. The provided changes are cleaned, validated, and stored to the source data object for this model. The source data is then re-initialized to apply those changes to the prepared data. The method returns an object of differential changes which modified the original data.
New values which should be applied to the data model
An object containing the changed keys and values
Copy and transform the DataModel into a plain object. Draw the values of the extracted object from the data source (by default) otherwise from its transformed values.
The extracted primitive object
Extract the source data for the DataModel into a simple object format that can be serialized.
The document source data expressed as a plain object
Configure the data model instance before validation and initialization workflows are performed.
Initialize the source data for a new DataModel instance. One-time migrations and initial cleaning operations are applied to the source data.
The candidate source data from which the model will be constructed
Migrated and cleaned source data which will be stored to the model instance
Initialize the instance by copying data from the source object to instance attributes. This mirrors the workflow of SchemaField#initialize but with some added functionality.
Jointly validate the overall data model after each field has been individually validated.
The candidate data object to validate
Define the data schema for documents of this type. The schema is populated the first time it is accessed and cached for future reuse.
Clean a data source object to conform to a specific provided schema.
The cleaned source data
Get an array of validation errors from the provided error structure
Create a new instance of this DataModel from a source record. The source is presumed to be trustworthy and is not strictly validated.
Initial document data which comes from a trusted source.
Model construction context
Create a DataModel instance using a provided serialized JSON string.
Serialized document data in string format
A constructed data model instance
Migrate candidate source data for this DataModel which may require initial cleaning or transformations.
The candidate source data from which the model will be constructed
Migrated source data, if necessary
Wrap data migration in a try/catch which attempts it safely
The candidate source data from which the model will be constructed
Migrated source data, if necessary
Take data which conforms to the current data schema and add backwards-compatible accessors to it in order to support older code which uses this data.
Data which matches the current schema
Additional shimming options
Data with added backwards-compatible properties
Update the source data for a specific DataSchema.
The data schema to update
Source data to be updated
Changes to apply to the source data
The updated source data
Update the source data for a specific DataField.
The field name being updated
The field definition being updated
The source object being updated
The new value for the field
Options which modify the update workflow
The abstract base class which defines the data schema contained within a Document.
Initial data used to construct the data object. The provided object will be owned by the constructed model instance and may be mutated.
Options which affect DataModel construction
A parent DataModel instance to which this DataModel belongs
Control the strictness of validation for initially provided data
