Method Summary

Modifier and Type	Method and Description
public static String	checkUnsupportedType(JavaType type) Helper method called by `com.fasterxml.jackson.databind.deser.BeanDeserializerFactory` and `com.fasterxml.jackson.databind.ser.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.
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 `com.fasterxml.jackson.annotation.JsonInclude.Include#NON_DEFAULT`.
protected static boolean	isCglibGetCallbacks(AnnotatedMethod am) This method was added to address the need to weed out CGLib-injected "getCallbacks" method.
protected static boolean	isGroovyMetaClassGetter(AnnotatedMethod am) Another helper method to deal with Groovy's problematic metadata accessors
public static boolean	isJava8OptionalClass(Class<?> rawType)
private static boolean	isJava8OptionalClass(String className)
public static boolean	isJava8TimeClass(Class<?> rawType)
private static boolean	isJava8TimeClass(String className)
public static boolean	isJodaTimeClass(Class<?> rawType)
private static boolean	isJodaTimeClass(String className)
protected static String	legacyManglePropertyName(final String Name of accessor/mutator method, not including prefix ("get"/"is"/"set") basename, final int offset) Method called to figure out name of the property, given corresponding suggested name based on a method or field name.
public static String	okNameForGetter(AnnotatedMethod am, boolean stdNaming) Deprecated Since 2.12 replaced with `com.fasterxml.jackson.databind.introspect.AccessorNamingStrategy`
public static String	okNameForIsGetter(AnnotatedMethod am, String name, boolean stdNaming) Deprecated Since 2.12 replaced with `com.fasterxml.jackson.databind.introspect.AccessorNamingStrategy`

getDefaultValue back to summary

getDefaultValue	back to summary
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 `com.fasterxml.jackson.annotation.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 `com.fasterxml.jackson.annotation.JsonInclude.Include#NON_DEFAULT` is used. Since 2.7

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 com.fasterxml.jackson.annotation.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 com.fasterxml.jackson.annotation.JsonInclude.Include#NON_DEFAULT is used.

Since: 2.7

isCglibGetCallbacks	back to summary
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[]"

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