Class SimpleType

      org.codehaus.jackson.map.type.SimpleType

public final class SimpleType
extends JavaType

Simple types are defined as anything other than one of recognized container types (arrays, Collections, Maps). For our needs we need not know anything further, since we have no way of dealing with generic types other than Collections and Maps.

Field Summary

protected Map<String,JavaType>	_typeParameters For generic types we need to keep track of mapping from formal into actual types, to be able to resolve generic signatures.
static SimpleType	TYPE_UNSPECIFIED This type token is used if the type is unknown due to type erasure.
static SimpleType	TYPE_WILDCARD This type token is used if the underlying type is only known as unqualified wildcard ("?").

boolean	equals(Object o)
JavaType	findVariableType(String name) Method that can be called to see if this type has generic type binding information for type variables, for given formal type parameter name.

Field Detail

TYPE_UNSPECIFIED

public static final SimpleType TYPE_UNSPECIFIED

This type token is used if the type is unknown due to type erasure.

TYPE_WILDCARD

public static final SimpleType TYPE_WILDCARD

This type token is used if the underlying type is only known as unqualified wildcard ("?").

_typeParameters

protected Map<String,JavaType> _typeParameters

For generic types we need to keep track of mapping from formal into actual types, to be able to resolve generic signatures.

Method Detail

_narrow

protected JavaType _narrow(Class<?> subclass)

Specified by:

_narrow in class JavaType

narrowContentsBy

public JavaType narrowContentsBy(Class<?> subclass)

Specified by:

narrowContentsBy in class JavaType

construct

public static SimpleType construct(Class<?> cls,
                                   Map<String,JavaType> typeParams)

addCommonTypes

protected static void addCommonTypes(Map<String,JavaType> types)

Method that can be called to add known simple types into given class-to-type map.

isFullyTyped

public boolean isFullyTyped()

Simple types are always fully typed, except for special placeholder types. Maintaining this constrain requires that no instances are ever created for Collection/Map types.

Specified by:

isFullyTyped in class JavaType

isContainerType

public boolean isContainerType()

Specified by:

isContainerType in class JavaType

Returns:

True if type represented is a container type; this includes array, Map and Collection types.

findVariableType

public JavaType findVariableType(String name)

Description copied from class: JavaType

Method that can be called to see if this type has generic type binding information for type variables, for given formal type parameter name.

Overrides:

findVariableType in class JavaType

Returns:

Type given formal type parameter name maps to, if any; null if this type knows of no binding for name

toString

public String toString()

Specified by:

toString in class JavaType

equals

public boolean equals(Object o)

Specified by:

equals in class JavaType
