Download the PHP package new-inventor/data-structure without Composer

Property bag

This utility provide to you data structure metadata and some useful classes.

With this packet you can transform arrays to needed format and load it to objects recursive.

Objects to load MUST implement Loadable or DataStructureInterface interface.

Installation

composer require new-inventor/data-structure

Examples

Metadata config

Recursive loading

You can load properties recursive by using RecursiveConstructor.

To use this you shoul add nested parameter to property like this

or

or

Namespace

It is the namespace for data structure class for recursive loading.

Validation

It is the symfony class validation config. You can pass it directly into property

Properties

It is properties of your data structure.

Property has this parameters:

• default
• transformers
• validation
• nested

If property === null(~) then default = null and no transformers and validators If property is string then default = null and default transformers = this string

transformers

Transformers is array of arrays.

In yml like this:

So you can set transformer like this:

By default transformer is inner transformer, but you can create you own and pass full class name to transformer config

Transformer can receive array or parameters and parameter can be array(1) with reserved word as key; Reserved words:

• static - interpret as static property of class ['class', 'propertyName']
• const - interpret as constant can be array like static or string
• groups - transformer groups, by default groups = ['default'].

If in transformers section more than 1 transformer in same group then this transformers will be wrapped by ChainTransformer, so this identical:

and

Validation

It is the getters part of symfony validation config for given property

Default

Default can be any value and have same reserved keys as transformer parameters, but group.

Nested

It is described in Recursive loading section.

PropertiesTransformer

or you can compose PropertiesTransformer by yourself

RecursiveConstructor

This constructor construct class with metadata by recursive loading it nested classes.
