ValueTypes

A ValueType describes the type of data that can be stored in a particular field of a DataElement. It specifies the format of the data and different representations in the various layers of the Application.

Several basic ValueTypes have defined in prime-core.

You can add new ValueTypes in one of 2 ways:

• Add a ValueType to one of your Components

Add to Component

ValueTypes are added to the valueTypes directory.

space
└── model
    ├── space.xml
    └── valueTypes
        ├── LicensePlate.xml
        └── Rating.xml

The xml itself should have root tag valueType and a type attribute (e.g. elements::SimpleValueType).

<valueType name="LicensePlate" type="elements::SimpleValueType">
  <description>For license plate String values.</description>
  <prototype name="String"/>
</valueType>

Add as DataResource

To provide a ValueType through an ExpansionResource, create a valueTypes.xml file somewhere in the resources directory.

space-expanders
└── data
    └── space
        └── valueTypes.xml

<dataResource type="elements::SimpleValueType">
  <simpleValueType name="LicensePlate">
    <description>For license plate String values.</description>
    <prototype name="String"/>
  </simpleValueType>
</dataResource>

Currently only SimpleValueTypes are supported. More ValueTypes will be coming in the near future.
