org.ujoframework.implementation.mapImpl
Class MapImplUjo

java.lang.Object
  extended by org.ujoframework.extensions.AbstractUjo
      extended by org.ujoframework.implementation.mapImpl.MapImplUjo
All Implemented Interfaces:
java.util.Map<java.lang.CharSequence,java.lang.Object>, UjoCloneable, UjoTextable, Ujo
Direct Known Subclasses:
MapImplUjoMiddle
public abstract class MapImplUjo
extends AbstractUjo
implements java.util.Map<java.lang.CharSequence,java.lang.Object>

The abstract String Map Ujo imlementation is an implementation of the UjoMiddle and Map<CharSequence,Object> interfaces. A child implementation can use "public static final UjoProperty" constants for its UjoProperties. The map key can be any CharSequence object include a direct UjoProperty from its implementation.
Notes:

Sample of usage

 import org.ujoframework.implementation.map.*;
 public class Person extends MapImplUjo {

    public static final UjoProperty<Person,String > NAME  = newProperty("name" , String.class);
    public static final UjoProperty<Person,Boolean> MALE  = newProperty("male" , Boolean.class);
    public static final UjoProperty<Person,Date   > BIRTH = newProperty("birth", Date.class);

 }

Since:
UJO release 0.85

Method Detail

writeValue

public void writeValue(UjoProperty property,
                       java.lang.Object value)
It is a common method for writing all object values, however there is strongly recomended to use a method Property.setValue(Ujo,Object) to an external access for a better type safe. The method have got a strategy place for an implementation of several listeners and validators.
NOTE: If property is an incorrect then no exception is throwed.

Specified by:
writeValue in interface Ujo
Parameters:
property - Property must be a direct type only!
See Also:
Property.setValue(Ujo,Object)

readValue

public java.lang.Object readValue(UjoProperty property)
It is a common method for reading all object values, however there is strongly recomended to use a method Property.getValue(Ujo) to an external access for a better type safe. The method have got a strategy place for an implementation of several listeners and convertors.
NOTE: If property is an incorrect then method returns a null value.

Specified by:
readValue in interface Ujo
Parameters:
property - Property must be a direct type only!
Returns:
Property value
See Also:
Property.getValue(Ujo)

Returns true if this map contains a mapping for the specified key.

Specified by:
containsKey in interface java.util.Map<java.lang.CharSequence,java.lang.Object>
Parameters:
key - Any CharSequence include a direct UjoProperty

containsValue

public boolean containsValue(java.lang.Object value)
Returns true if this map maps one or more keys to the specified value.

Specified by:
containsValue in interface java.util.Map<java.lang.CharSequence,java.lang.Object>

get

Specified by:
put in interface java.util.Map<java.lang.CharSequence,java.lang.Object>
Parameters:
key - Any CharSequence include a direct UjoProperty
