Class Overview
Type abstraction that represents Java type that has been resolved
(i.e. has all generic information, if any, resolved to concrete
types).
Note that this is an intermediate type, and all concrete instances
MUST be of type JavaType from "databind" bundle -- this
abstraction is only needed so that types can be passed through
readValueAs(TypeReference) methods.

(like arrays, Collections and Maps)

Public Methods
public abstract ResolvedType containedType (int index)
Method for accessing definitions of contained ("child") types.
Parameters
| index | Index of contained type to return |
|---|
Returns
- Contained type at index, or null if no such type exists (no exception thrown)
public abstract int containedTypeCount ()
Method for checking how many contained types this type has. Contained types are usually generic types, so that generic Maps have 2 contained types.
public abstract String containedTypeName (int index)
Method for accessing name of type variable in indicated position. If no name is bound, will use placeholders (derived from 0-based index); if no type variable or argument exists with given index, null is returned.
Parameters
| index | Index of contained type to return |
|---|
Returns
- Contained type at index, or null if no such type exists (no exception thrown)
public abstract ResolvedType getContentType ()
Method for accessing content type of this type, if type has such a thing: simple types do not, structured types do (like arrays, Collections and Maps)
public abstract ResolvedType getKeyType ()
Method for accessing key type for this type, assuming type has such a concept (only Map types do)
public abstract boolean hasGenericTypes ()
Method that can be used to find out if the type directly declares generic parameters (for its direct super-class and/or super-interfaces).
public abstract boolean isAbstract ()
public abstract boolean isArrayType ()
public abstract boolean isCollectionLikeType ()
public abstract boolean isConcrete ()
public abstract boolean isContainerType ()
public abstract boolean isEnumType ()
public abstract boolean isFinal ()
public abstract boolean isInterface ()
public abstract boolean isMapLikeType ()
public abstract boolean isPrimitive ()
public abstract boolean isThrowable ()
public abstract String toCanonical ()
Method that can be used to serialize type into form from which
it can be fully deserialized from at a later point (using
TypeFactory from mapper package).
For simple types this is same as calling
getName(), but for structured types it may additionally
contain type information about contents.
