public class MapLikeType extends TypeBase
Map
, but that do not have enough
introspection functionality to allow for some level of generic handling.
This specifically allows framework to check for configuration and annotation
settings used for Map types, and pass these to custom handlers that may be more
familiar with actual type.限定符和类型 | 字段和说明 |

_keyType
Type of keys of Map.

Type of values of Map.

JavaType |
containedType(int index)
Method for accessing definitions of contained ("child")
types.
|
int |
containedTypeCount()
Method for checking how many contained types this type
has.
|
String |
containedTypeName(int index)
Not sure if we should count on this, but type names
for core interfaces are "K" and "V" respectively.
|
boolean |
equals(Object o) |
JavaType |
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)
|
StringBuilder |
getErasedSignature(StringBuilder sb)
Method for accessing signature without generic
type information, in form compatible with all versions
of JVM, and specifically used for type descriptions
when generating byte code.
|
StringBuilder |
getGenericSignature(StringBuilder sb) |
JavaType |
getKeyType()
Method for accessing key type for this type, assuming type
has such a concept (only Map types do)
|
boolean |
isContainerType() |
boolean |
isMapLikeType() |
boolean |
isTrueMapType()
Method that can be used for checking whether this type is a
"real" Collection type; meaning whether it represents a parameterized
subtype of
Collection or just something that acts
like one. |
