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

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.

Constructor Summary

TypeBindings(TypeFactory typeFactory, Class<?> cc)

TypeBindings(TypeFactory typeFactory, JavaType type)

Method Summary

void	_addPlaceholder(String name)
protected void	_resolve()
protected void	_resolveBindings(Type t)
void	addBinding(String name, JavaType type)
TypeBindings	childInstance() Constructor used to create "child" instances; mostly to allow delegation from explicitly defined local overrides (local type variables for methods, constructors) to contextual (class-defined) ones.
JavaType	findType(String name)
int	getBindingCount()
JavaType	resolveType(Class<?> cls)
JavaType	resolveType(Type type)

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.
