Class DataType

java.lang.Object
com.luciad.datamodels.DataType
All Implemented Interfaces:
AutoCloseable
public final class DataType extends Object implements AutoCloseable
A representation of the type of a data object.

A type describes the structure of a data object as a list of properties. Each of these properties is itself of a certain type.

A type is either a primitive type or a data object type. Primitive types are types which have no internal structure (no properties) and typically represent simple object such as strings, numbers etc. All primitive types are accessible from this class (see e.g. getIntType(), getStringType() ...).

Application-specific metadata can be attached to a type in the form of a DataAnnotation.

New types can be defined using a DataType.Builder (see newBuilder()).

Instances of this class are thread safe. Once an instance has been created, there is no public API to modify it.
