Class TypeBindings

java.lang.Object

com.fasterxml.jackson.databind.type.TypeBindings

public class TypeBindings
extends Object

Helper class used for resolving type parameters for given class

Field Summary

Fields

Modifier and Type	Field and Description
protected Map<String,JavaType>	_bindings Lazily-instantiated bindings of resolved type parameters
protected Class<?>	_contextClass Specific class to use for resolving all types, for methods and fields class and its superclasses and -interfaces contain.
protected JavaType	_contextType Context type used for resolving all types, if specified.
protected HashSet<String>	_placeholders Also: we may temporarily want to mark certain named types as resolved (but without exact type); if so, we'll just store names here.
protected TypeFactory	_typeFactory Factory to use for constructing resolved related types.
static JavaType	UNBOUND Marker to use for (temporarily) unbound references.

Field Detail

UNBOUND

public static final JavaType UNBOUND

Marker to use for (temporarily) unbound references.

_typeFactory

protected final TypeFactory _typeFactory

Factory to use for constructing resolved related types.

_contextType

protected final JavaType _contextType

Context type used for resolving all types, if specified. May be null, in which case _contextClass is used instead.

_contextClass

protected final Class<?> _contextClass

Specific class to use for resolving all types, for methods and fields class and its superclasses and -interfaces contain.

_bindings

protected Map<String,JavaType> _bindings

Lazily-instantiated bindings of resolved type parameters

_placeholders

protected HashSet<String> _placeholders

Also: we may temporarily want to mark certain named types as resolved (but without exact type); if so, we'll just store names here.
