Method Summary

Modifier and Type	Method	Description
static String	checkUnsupportedType(JavaType type)	Helper method called by BeanDeserializerFactory and BeanSerializerFactory to check if given unrecognized type (to be (de)serialized as general POJO) is one of "well-known" types for which there would be a datatype module; and if so, return appropriate failure message to give to caller.
static Object	getDefaultValue(JavaType type)	Accessor used to find out "default value" to use for comparing values to serialize, to determine whether to exclude value from serialization with inclusion type of JsonInclude.Include.NON_DEFAULT.
static boolean	isJava8TimeClass(Class<?> rawType)
static boolean	isJodaTimeClass(Class<?> rawType)
static String	okNameForGetter(AnnotatedMethod am, boolean stdNaming)	Deprecated. Since 2.12 replaced with AccessorNamingStrategy
static String	okNameForIsGetter(AnnotatedMethod am, String name, boolean stdNaming)	Deprecated. Since 2.12 replaced with AccessorNamingStrategy
static String	okNameForMutator(AnnotatedMethod am, String prefix, boolean stdNaming)	Deprecated. Since 2.12 replaced with AccessorNamingStrategy

getDefaultValue

public static Object getDefaultValue(JavaType type)

Accessor used to find out "default value" to use for comparing values to serialize, to determine whether to exclude value from serialization with inclusion type of JsonInclude.Include.NON_DEFAULT.

Default logic is such that for primitives and wrapper types for primitives, expected defaults (0 for `int` and `java.lang.Integer`) are returned; for Strings, empty String, and for structured (Maps, Collections, arrays) and reference types, criteria JsonInclude.Include.NON_DEFAULT is used.

Note: public only since 2.11
