Interface ObjectType

All Superinterfaces:

DataSerializable, Serializable

All Known Subinterfaces:

CollectionType, MapType, StructType

public interface ObjectType
extends DataSerializable

An ObjectType represents the type of an object in a query. An ObjectType is similar to a Class, except unlike a Class it can be extended to add more information such as a subtype for collection Classes, a key type for a map class, or a field information for structs. Note that multiple instances of are allowed of the same type, so ObjectTypes should always be compared using equals.

Method Detail

isCollectionType

boolean isCollectionType()

Return true if this is a CollectionType. Note that MapTypes, Region types, and array types are also considered CollectionTypes in the context of the query language and therefore return true to this method.

isMapType

boolean isMapType()

Return true if this is a MapType

isStructType

boolean isStructType()

Return true if this is a StructType

getSimpleClassName

String getSimpleClassName()

Returns:

the simple name for the class this resolves to without including the package
