Method Detail

withResolved

protected ReferenceTypeSerializer<Optional<?>> withResolved(BeanProperty prop,
                                                            TypeSerializer vts,

Description copied from class: ReferenceTypeSerializer

Mutant factory method called when changes are needed; should construct newly configured instance with new values as indicated.

NOTE: caller has verified that there are changes, so implementations need NOT check if a new instance is needed.

Specified by:

withResolved in class ReferenceTypeSerializer<Optional<?>>

withContentInclusion

public ReferenceTypeSerializer<Optional<?>> withContentInclusion(Object suppressableValue,
                                                                 boolean suppressNulls)

Description copied from class: ReferenceTypeSerializer

Mutant factory method called to create a differently constructed instance, specifically with different exclusion rules for contained value.

NOTE: caller has verified that there are changes, so implementations need NOT check if a new instance is needed.

Specified by:

withContentInclusion in class ReferenceTypeSerializer<Optional<?>>

_isValuePresent

protected boolean _isValuePresent(Optional<?> value)

Description copied from class: ReferenceTypeSerializer

Method called to see if there is a value present or not. Note that value itself may still be `null`, even if present, if referential type allows three states (absent, present-null, present-non-null); some only allow two (absent, present-non-null).

Specified by:

_isValuePresent in class ReferenceTypeSerializer<Optional<?>>

_getReferenced

protected Object _getReferenced(Optional<?> value)

Specified by:

_getReferenced in class ReferenceTypeSerializer<Optional<?>>

_getReferencedIfPresent

protected Object _getReferencedIfPresent(Optional<?> value)

Specified by:

_getReferencedIfPresent in class ReferenceTypeSerializer<Optional<?>>
