Class MinimalClassNameIdResolver

java.lang.Object

com.fasterxml.jackson.databind.jsontype.impl.TypeIdResolverBase

com.fasterxml.jackson.databind.jsontype.impl.ClassNameIdResolver

com.fasterxml.jackson.databind.jsontype.impl.MinimalClassNameIdResolver

All Implemented Interfaces:

TypeIdResolver, Serializable

public class MinimalClassNameIdResolver
extends ClassNameIdResolver

Specialization of ClassNameIdResolver that instead uses a "minimal" derivation of Class name, using relative reference from the base type (base class) that polymorphic value has.

Modifier and Type	Field	Description
protected final String	_basePackageName	Package name of the base class, to be used for determining common prefix that can be omitted from included type id.
protected final String	_basePackagePrefix	Same as _basePackageName, but includes trailing dot.

Field Details

_basePackageName

protected final String _basePackageName

Package name of the base class, to be used for determining common prefix that can be omitted from included type id. Does not include the trailing dot.

_basePackagePrefix

protected final String _basePackagePrefix

Same as _basePackageName, but includes trailing dot.

 TypeFactory typeFactory,
 PolymorphicTypeValidator ptv)

Method Details

construct

public static MinimalClassNameIdResolver construct(JavaType baseType,
 MapperConfig<?> config,
 PolymorphicTypeValidator ptv)

getMechanism

public com.fasterxml.jackson.annotation.JsonTypeInfo.Id getMechanism()

Description copied from interface: TypeIdResolver

Accessor for mechanism that this resolver uses for determining type id from type. Mostly informational; not required to be called or used.

Specified by:

getMechanism in interface TypeIdResolver

Overrides:

getMechanism in class ClassNameIdResolver

idFromValue

public String idFromValue(Object value)

Description copied from interface: TypeIdResolver

Method called to serialize type of the type of given value as a String to include in serialized JSON content.

Specified by:

idFromValue in interface TypeIdResolver

Overrides:

idFromValue in class ClassNameIdResolver

idFromValueAndType

public String idFromValueAndType(Object value,
 Class<?> rawType)

Description copied from interface: TypeIdResolver

Alternative method used for determining type from combination of value and type, using suggested type (that serializer provides) and possibly value of that type. Most common implementation will use suggested type as is.

Specified by:

idFromValueAndType in interface TypeIdResolver

Overrides:

idFromValueAndType in class ClassNameIdResolver

_typeFromId

protected JavaType _typeFromId(String id,
 DatabindContext ctxt)
                        throws IOException

Overrides:

_typeFromId in class ClassNameIdResolver

Throws:

IOException
