Enum LoopFormState
- All Implemented Interfaces:
Serializable
,Comparable<LoopFormState>
,java.lang.constant.Constable
Identifies how a
LoopFormState
component stores state into the FormSupport
object.- Since:
- 5.1.0.4

Enum Constant Summary
Enum ConstantsEnum ConstantDescriptionOnly enough state to iterate over the source values is stored.No state of any kind is stored, as if the Loop was not contained within aForm
.Stores a sequence of values (obtained via aValueEncoder
) into the Form state. -
Method Summary
Modifier and TypeMethodDescriptionstatic LoopFormState
Returns the enum constant of this type with the specified name.static LoopFormState[]
values()
Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Details
-
NONE
No state of any kind is stored, as if the Loop was not contained within aForm
. -
ITERATION
Only enough state to iterate over the source values is stored. When the Form is submitted, the Loop will re-acquire its source and iterate over it. This is equivalent to "volatile" mode in Tapestry 5.0. This can be subject to race conditions when the values within the source change between render and submit. -
VALUES
Stores a sequence of values (obtained via aValueEncoder
) into the Form state. The source parameter is not re-acquired when the Form is submitted.

values
Returns an array containing the constants of this enum type, in the order they are declared.- Returns:
- an array containing the constants of this enum type, in the order they are declared

valueOf
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant with the specified nameNullPointerException
- if the argument is null
