T
- the Java type that instances described by this type must have. For example, SimpleType.INTEGER
is a
SimpleType<Integer>
which is a subclass of OpenType<Integer>
, meaning that an attribute, parameter, or return value that is described as a SimpleType.INTEGER
must have Java type Integer

OpenType
class is the parent abstract class of all classes which describe the actual open type of open data values. An open type is defined by:

),Modifier and Type | Field | Description |
---|---|---|
static final String[] |
ALLOWED_CLASSNAMES |
Deprecated. |
static final List |
ALLOWED_CLASSNAMES_LIST |
List of the fully qualified names of the Java classes allowed for open data values. |
Modifier | Constructor | Description |
---|---|---|
protected |
Constructs an OpenType instance (actually a subclass instance as OpenType is abstract), checking for the validity of the given parameters. |
Modifier and Type | Method | Description |
---|---|---|
abstract boolean |
equals |
Compares the specified obj parameter with this open type instance for equality. |
String |
getClassName() |
Returns the fully qualified Java class name of the open data values this open type describes. |
String |
getDescription() |
Returns the text description of this OpenType instance. |
String |
getTypeName() |
Returns the name of this OpenType instance. |
abstract int |
hashCode() |
Returns a hash code value for the object. |
boolean |
isArray() |
Returns true if the open data values this open type describes are arrays, false otherwise. |
abstract boolean |
isValue |
Tests whether obj is a value for this open type. |
abstract String |
toString() |
Returns a string representation of this open type instance. |
