Method Summary

<UJO extends AbstractMetaModel,VALUE> VALUE	get(UjoProperty<UJO,VALUE> property) Getter based on one UjoProperty
protected <UJO extends Ujo,VALUE> void	changeDefault(UJO ujo, UjoProperty<UJO,VALUE> property, VALUE value) Assign a 'valid value' over a default UJO property value only
boolean	checkReadOnly(boolean exception) Test a read-only state
protected boolean	isUsable(java.lang.CharSequence text) Returns true, if the argument text is not null and not empty.
protected boolean	isUsable(java.lang.Object value) Returns true, if the argument text is not null and not empty.
boolean	readAuthorization(UjoAction action, UjoProperty property, java.lang.Object value) Get an authorization of the property for different actions.
boolean	readOnly() Property values can be readed only
void	setReadOnly(boolean recurse) Set a read-only state.
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(org.ujoframework.Ujo, java.lang.Object) to an external access for a better type safe.

Method Detail

readOnly

public boolean readOnly()

Property values can be readed only

setReadOnly

public void setReadOnly(boolean recurse)

Set a read-only state.

checkReadOnly

public boolean checkReadOnly(boolean exception)
                      throws java.lang.UnsupportedOperationException

Test a read-only state

Throws:

java.lang.UnsupportedOperationException

writeValue

public void writeValue(UjoProperty property,
                       java.lang.Object value)

Description copied from class: QuickUjo

It is a common method for writing all object values, however there is strongly recomended to use a method Property.setValue(org.ujoframework.Ujo, java.lang.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 method can throws an ArrayIndexOutOfBoundsException.

Specified by:

writeValue in interface Ujo

Overrides:

writeValue in class QuickUjo

Parameters:

property - Property must be a direct type only!

See Also:

Property.setValue(Ujo,Object)

changeDefault

protected <UJO extends Ujo,VALUE> void changeDefault(UJO ujo,
                                                     UjoProperty<UJO,VALUE> property,
                                                     VALUE value)

Assign a 'valid value' over a default UJO property value only

readAuthorization

public boolean readAuthorization(UjoAction action,
                                 UjoProperty property,
                                 java.lang.Object value)

Description copied from class: AbstractUjo

Get an authorization of the property for different actions.
A Default value is TRUE for all actions, properties and values.

Specified by:

readAuthorization in interface Ujo

Overrides:

readAuthorization in class AbstractUjo

Parameters:

action - Type of request. See constant(s) ACTION_* for more information. The action must not be null, however there is allowed to use a dummy constant UjoAction.DUMMY .

property - A property of the Ujo

value - A value

Returns:

Returns TRUE, if property is authorized.
