Method Summary

Modifier and Type	Method and Description
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.
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
protected static boolean	isGroovyMetaClassSetter(AnnotatedMethod am) Similar to isCglibGetCallbacks(com.fasterxml.jackson.databind.introspect.AnnotatedMethod), need to suppress a cyclic reference.
protected static String	legacyManglePropertyName(String basename, int offset) Method called to figure out name of the property, given corresponding suggested name based on a method or field name.

okNameForGetter

public static String okNameForGetter(AnnotatedMethod am,
                                     boolean stdNaming)

Since:

2.5

okNameForRegularGetter

public static String okNameForRegularGetter(AnnotatedMethod am,
                                            String name,
                                            boolean stdNaming)

Since:

2.5

okNameForIsGetter

public static String okNameForIsGetter(AnnotatedMethod am,
                                       String name,
                                       boolean stdNaming)

Since:

2.5

okNameForSetter

@Deprecated
public static String okNameForSetter(AnnotatedMethod am,
                                                 boolean stdNaming)

Deprecated.

Since:

2.5

okNameForMutator

public static String okNameForMutator(AnnotatedMethod am,
                                      String prefix,
                                      boolean stdNaming)

Since:

2.5

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.

Since:

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[]"

isGroovyMetaClassSetter

protected static boolean isGroovyMetaClassSetter(AnnotatedMethod am)

Similar to isCglibGetCallbacks(com.fasterxml.jackson.databind.introspect.AnnotatedMethod), need to suppress a cyclic reference.

isGroovyMetaClassGetter

protected static boolean isGroovyMetaClassGetter(AnnotatedMethod am)

Another helper method to deal with Groovy's problematic metadata accessors

legacyManglePropertyName

protected static String legacyManglePropertyName(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 String stdManglePropertyName(String basename,
                                           int offset)

Note: public only since 2.11
