Internal structures	11

This package has some internal structures which are used to analyze data objects and their properties. They can be helpful when writing casts, transformers or rule inferrers.

DataClass

The DataClass represents the structure of a data object and has the following properties:

• name the name of the data class
• properties all the DataProperty's of the class (more on that later)
• methods all the magical creation DataMethods of the class (more on that later)
• constructorMethod the constructor DataMethod of the class
• isReadOnly is the class read only
• isAbstract is the class abstract
• appendable is the class implementing AppendableData
• includeable is the class implementing IncludeableData
• responsable is the class implementing ResponsableData
• transformable is the class implementing TransformableData
• validatable is the class implementing ValidatableData
• wrappable is the class implementing WrappableData
• emptyData the the class implementing EmptyData
• attributes a collection of resolved attributes assigned to the class
• dataCollectablePropertyAnnotations the property annotations of the class used to infer the data collection type
• allowedRequestIncludes the allowed request includes of the class
• allowedRequestExcludes the allowed request excludes of the class
• allowedRequestOnly the allowed request only of the class
• allowedRequestExcept the allowed request except of the class
• outputMappedProperties properties names which are mapped when transforming the data object
• transformationFields structure of the transformation fields

DataProperty

A data property represents a single property within a data object.

• name the name of the property
• className the name of the class of the property
• type the DataPropertyType of the property (more on that later)
• validate should the property be automatically validated
• computed is the property computed
• hidden will the property be hidden when transforming the data object
• isPromoted is the property constructor promoted
• isReadOnly is the property read only
• hasDefaultValue has the property a default value
• defaultValue the default value of the property
• cast the cast assigned to the property
• transformer the transformer assigned to the property
• inputMappedName the name used to map a property name given
• outputMappedName the name used to map a property name onto
• attributes a collection of resolved attributes assigned to the property

DataMethod

A data method represents a method within a data object.

• name the name of the method
• parameters all the DataParameter's and DataPropertys of the method (more on that later)
• isStatic whether the method is static
• isPublic whether the method is public
• isCustomCreationMethod whether the method is a custom creation method (=magical creation method)
• returnType the DataType of the return value (more on that later)

DataParameter

A data parameter represents a single parameter/property within a data method.

• name the name of the parameter
• isPromoted is the property/parameter constructor promoted
• hasDefaultValue has the parameter a default value
• defaultValue the default value of the parameter
• type the DataType of the parameter (more on that later)

DataType

A data type represents a type within a data object.

• Type can be a NamedType, UnionType or IntersectionType (more on that later)
• isNullable can the type be nullable
• isMixed is the type a mixed type
• kind the DataTypeKind of the type (more on that later)

DataPropertyType

Extends from the DataType and has the following additional properties:

• isOptional can the type be optional
• lazyType the class of the lazy type for the property
• dataClass the data object class of the property or the data object class of the collection it collects
• dataCollectableClass the collectable type of the data objects
• kind the DataTypeKind of the type (more on that later)

DataTypeKind

An enum representing the kind of type of a property/parameter with respect to the package:

• Default: a non package specific type
• DataObject: a data object
• DataCollection: a DataCollection of data objects
• DataPaginatedCollection: a DataPaginatedCollection of data objects
• DataCursorPaginatedCollection: a DataCursorPaginatedCollection of data objects
• DataArray: an array of data objects
• DataEnumerable: a Enumerable of data objects
• DataPaginator: a Paginator of data objects
• DataCursorPaginator: a CursorPaginator of data objects

NamedType

Represents a named PHP type with the following properties:

• name the name of the type
• builtIn is the type a built-in type
• acceptedTypes an array of accepted types as string
• kind the DataTypeKind of the type (more on that later)
• dataClass the data object class of the property or the data object class of the collection it collects
• dataCollectableClass the collectable type of the data objects
• isCastable wetter the type is a Castable

UnionType / IntersectionType

Represents a union or intersection of types with the following properties:

• types an array of types (can be NamedType, UnionType or IntersectionType)
