public static final String VALIDATOR_ID
The standard converter id for this converter.
public static final String MAXIMUM_MESSAGE_ID
The message identifier of the FacesMessage
to be created if
the maximum value check fails. The message format string for
this message may optionally include the following placeholders:
{0}
replaced by the configured maximum value.{1}
replaced by a String
whose value
is the label of the input component that produced this message.
public static final String MINIMUM_MESSAGE_ID
The message identifier of the FacesMessage
to be created if
the minimum value check fails. The message format string for
this message may optionally include the following placeholders:
{0}
replaced by the configured minimum value.{1}
replaced by a String
whose value
is the label of the input component that produced this message.
public static final String NOT_IN_RANGE_MESSAGE_ID
The message identifier of the FacesMessage
to be created if
the maximum or minimum value check fails, and both the maximum
and minimum values for this validator have been set. The message
format string for this message may optionally include the following
placeholders:
{0}
replaced by the configured minimum value.{1}
replaced by the configured maximum value.{2}
replaced by a String
whose value
is the label of the input component that produced this message.
public static final String TYPE_MESSAGE_ID
The message identifier of the FacesMessage
to be created if
the current value of this component is not of the correct type.
The message format string for this message may
optionally include a {0}
placeholder that will be
replaced by a String
whose value is the label of
the input component that produced this message.

public Object saveState(FacesContext context)
StateHolder
Gets the state of the instance as a
Serializable
Object.
If the class that implements this interface has references to
instances that implement StateHolder (such as a
UIComponent
with event handlers, validators, etc.)
this method must call the StateHolder.saveState(javax.faces.context.FacesContext)
method on all those
instances as well. This method must not save the state
of children and facets. That is done via the StateManager
This method must not alter the state of the implementing object. In other words, after executing this code:
Object state = component.saveState(facesContext);
component
should be the same as before executing
it.
The return from this method must be Serializable

public void restoreState(FacesContext context, Object state)
StateHolder
Perform any processing required to restore the state from the entries in the state Object.
If the class that implements this interface has references to
instances that also implement StateHolder (such as a
UIComponent
with event handlers, validators, etc.)
this method must call the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object)
method on all those
instances as well.
