Field Details

generator

public final ObjectIdGenerator<?> generator

id

public Object id

idWritten

protected boolean idWritten

Marker to denote whether Object Id value has been written as part of an Object, to be referencible. Remains false when forward-reference is written.

public WritableObjectId(ObjectIdGenerator<?> g)

Method Details

writeAsReference

public boolean writeAsReference(JsonGenerator g,
 SerializationContext ctxt,
 ObjectIdWriter w)
                         throws JacksonException

Method to call to write a reference to object that this id refers. Usually this is done after an earlier call to writeAsDeclaration(tools.jackson.core.JsonGenerator, tools.jackson.databind.SerializationContext, tools.jackson.databind.ser.impl.ObjectIdWriter).

Throws:

JacksonException

generateId

public Object generateId(Object forPojo)

writeAsDeclaration

public void writeAsDeclaration(JsonGenerator g,
 SerializationContext ctxt,
 ObjectIdWriter w)
                        throws JacksonException

Method called to output Object Id declaration, either using native Object Id write method JsonGenerator.writeObjectId(Object) (if allowed), or, if not, just writing it as an Object property with specified property name and id value.

Throws:

JacksonException
