Class ResolvedType

java.lang.Object
  com.fasterxml.jackson.core.type.ResolvedType

public abstract class ResolvedType
extends Object

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 JsonParser.readValueAs(java.lang.Class) methods.

Since:

2.0

Method Summary

abstract ResolvedType	containedType(int index) Method for accessing definitions of contained ("child") types.
abstract int	containedTypeCount() Method for checking how many contained types this type has.
abstract String	containedTypeName(int index) Method for accessing name of type variable in indicated position.
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)
abstract ResolvedType	getKeyType() Method for accessing key type for this type, assuming type has such a concept (only Map types do)
abstract Class<?>	getRawClass() Accessor for type-erased Class of resolved type.
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).
abstract boolean	hasRawClass(Class<?> clz)
abstract boolean	isAbstract()
abstract boolean	isArrayType()

abstract boolean	isEnumType()
abstract boolean	isFinal()
abstract boolean	isInterface()
abstract boolean	isMapLikeType()
abstract boolean	isPrimitive()

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).

Method Detail

getRawClass

public abstract Class<?> getRawClass()

Accessor for type-erased Class of resolved type.

hasRawClass

public abstract boolean hasRawClass(Class<?> clz)

isAbstract

public abstract boolean isAbstract()

isConcrete

public abstract boolean isConcrete()

isThrowable

public abstract boolean isThrowable()

isArrayType

public abstract boolean isArrayType()

isEnumType

public abstract boolean isEnumType()

isInterface

public abstract boolean isInterface()

isPrimitive

public abstract boolean isPrimitive()

isFinal

public abstract boolean isFinal()

isContainerType

public abstract boolean isContainerType()

isCollectionLikeType

public abstract boolean isCollectionLikeType()

isMapLikeType

public abstract boolean isMapLikeType()

hasGenericTypes

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).

getKeyType

public abstract ResolvedType getKeyType()

Method for accessing key type for this type, assuming type has such a concept (only Map types do)

getContentType

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)

containedTypeCount

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.

containedType

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)

containedTypeName

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)

toCanonical

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 Class.getName(), but for structured types it may additionally contain type information about contents.
