Method Detail
isNull
default boolean isNull()
Returns if the value isnull, i.e. undefined.- Returns:
trueif 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
isNullAllowedto false when the value already isnullwill 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:
java.lang.IllegalStateException- If the flagisNullAllowed()false.
