Method Detail

bindBeanMap

public static Map<Integer,String> bindBeanMap(Object bean,
                                              Map<String,Object> map,
                                              boolean beanToMap,
                                              boolean validate)

Copies all properties annotated by Bind to a map.

Parameters:

bean - the bean to copy from/to

map - the map to use

beanToMap - if true then data from the bean are copied into the map. If false then map's data will be copied into the bean.

validate - if true then validation constraints are checked.

Returns:

an empty map if no validation constraints were violated; a map of view id to an error message if violation occured.

bindBeanToEditor

public static Map<Integer,String> bindBeanToEditor(Object bean,
                                                   SharedPreferences.Editor editor,
                                                   boolean validate)

Copies all properties annotated by Bind to an editor.

Parameters:

bean - the bean to copy from

editor - the map to use

validate - if true then validation constraints are checked.

Returns:

an empty map if no validation constraints were violated; a map of view id to an error message if violation occured.

put

public static <V> void put(String k,
                           V v,
                           Class<? extends V> type,
                           SharedPreferences.Editor editor)

Puts given object into an editor.

Type Parameters:

V - the value type

Parameters:

k - key name

v - value

type - the value class

editor - the editor.

bindBeanView

public static Map<Integer,String> bindBeanView(Object bean,
                                               View parent,
                                               boolean beanToView,
                                               boolean validate)

Copies all properties annotated by Bind to the view.

Parameters:

bean - the bean to copy from/to

parent - the view to use for performing View lookup.

beanToView - if true then data from the bean are copied into the view. If false then view's data will be copied into the bean.

validate - if true then validation constraints are checked.

Returns:

an empty map if no validation constraints were violated; a map of view id to an error message if violation occurred.

copy

public static <T> void copy(T from,
                            T to)

Copies all bindable properties from given bean to given bean.

Type Parameters:

T - the bean type

Parameters:

from - source bean

to - target bean
