Constructor Details

FieldProperty

public FieldProperty(ObjectifyFactory fact,
 Class<?> examinedClass,
 Field field)

Parameters:

examinedClass - is the actual top level concrete class we are examining; the field might be declared on a superclass of this class so it's not the same as field.getDeclaringClass()

Method Details

getType

public Type getType()

Description copied from interface: Property

Get the real generic type of the field

set

public void set(Object pojo,
 Object value)

Description copied from interface: Property

Actually set the property (field or method) on an object

get

public Object get(Object pojo)

Description copied from interface: Property

Get the value of the property (field) if possible, or null if not possible (method)

toString

public String toString()

Overrides:

toString in class Object

isSaved

public boolean isSaved(Object onPojo)

Returns:

true if this field should be saved, false if not

getIndexInstruction

public Boolean getIndexInstruction(Object onPojo)

Description copied from interface: Property

Gets the index instruction for this property, if there is one. Properties do not necessarily have a specific index or unindex instruction, and even if they do, the instruction might be conditional. Also factors in any index instruction on the class as a default. However, explicit index instruction on the field overrides the class.

Returns:

true if this field should be indexed, false if it should be unindexed, null is "no information, continue with defaults".
