Method Detail

isNull

default boolean isNull()

Returns if the value is null, i.e. undefined.

Returns:

true if the value is null or undefined, false if defined or non-null.

isNullAllowed

default boolean isNullAllowed()

Returns if a null value is allowed, i.e. no date/time value is set and the UI component is blank.

Returns:

true if null is allowed, or false (default) if not allowed.

setNullAllowed

default boolean setNullAllowed(boolean isNullAllowed)

Sets the null value allowed flag, i.e. allows no date/time value to be set and the UI component is blank.

Setting this parameter isNullAllowed to false when the value already is null will not affect the value.

Parameters:

isNullAllowed - Flag for null allowed.

Returns:

true if the setting changed, false for no change.

setValueToNull

default boolean setValueToNull()

Sets the value to null.

Returns:

true for value changed, false for no change.

Throws:

IllegalStateException - If the flag isNullAllowed() is false.
