getInternalName

public String getInternalName()

Description copied from class: BeanPropertyDefinition

Description copied from class: BeanPropertyDefinition

Accessor that can be called to check whether property was included due to an explicit marker (usually annotation), or just by naming convention.

Specified by:

isExplicitlyIncluded in class BeanPropertyDefinition

Returns:

True if property was explicitly included (usually by having one of components being annotated); false if inclusion was purely due to naming or visibility definitions (that is, implicit)

isExplicitlyNamed

Description copied from class: BeanPropertyDefinition

Accessor that can be called to check whether property name was due to an explicit marker (usually annotation), or just by naming convention or use of "use-default-name" marker (annotation).

Overrides:

isExplicitlyNamed in class BeanPropertyDefinition

 POJOPropertyBuilder.Linked<AnnotatedMethod> next)

Helper method called in cases where we have encountered two setter methods that have same precedence and cannot be resolved.
