      • getDefaultValue

        public static java.lang.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.

        2.7

      • isCglibGetCallbacks

        protected static boolean isCglibGetCallbacks​(AnnotatedMethod am)
        This method was added to address the need to weed out CGLib-injected "getCallbacks" method. At this point caller has detected a potential getter method with name "getCallbacks" and we need to determine if it is indeed injectect by Cglib. We do this by verifying that the result type is "net.sf.cglib.proxy.Callback[]"

      • isGroovyMetaClassGetter

        protected static boolean isGroovyMetaClassGetter​(AnnotatedMethod am)
        Another helper method to deal with Groovy's problematic metadata accessors

      • legacyManglePropertyName

        protected static java.lang.String legacyManglePropertyName​(java.lang.String basename,
                                                           int offset)
        Method called to figure out name of the property, given corresponding suggested name based on a method or field name.
        Parameters:
        basename - Name of accessor/mutator method, not including prefix ("get"/"is"/"set")

      • stdManglePropertyName

        public static java.lang.String stdManglePropertyName​(java.lang.String basename,

      • checkUnsupportedType

        public static java.lang.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.
