okNameForGetter
@Deprecated public static java.lang.String okNameForGetter(AnnotatedMethod am, boolean stdNaming)
Deprecated.Since 2.12 replaced withAccessorNamingStrategy
- Since:
- 2.5
-
okNameForRegularGetter
@Deprecated public static java.lang.String okNameForRegularGetter(AnnotatedMethod am, java.lang.String name, boolean stdNaming)
Deprecated.Since 2.12 replaced withAccessorNamingStrategy
- Since:
- 2.5
-
okNameForIsGetter
@Deprecated public static java.lang.String okNameForIsGetter(AnnotatedMethod am, java.lang.String name, boolean stdNaming)
Deprecated.Since 2.12 replaced withAccessorNamingStrategy
- Since:
- 2.5
-
okNameForSetter
@Deprecated public static java.lang.String okNameForSetter(AnnotatedMethod am, boolean stdNaming)
Deprecated.
-
okNameForMutator
@Deprecated public static java.lang.String okNameForMutator(AnnotatedMethod am, java.lang.String prefix, boolean stdNaming)

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 ofJsonInclude.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[]"
-
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, int offset)
Note: public only since 2.11- Since:
- 2.5
-
