public interface ChannelAccessAlarmOnlyShort extends ChannelAccessAlarmShort, ChannelAccessAlarmOnlyValue<java.lang.Short>
Channel Access value that represents the
DBR_STS_SHORT
type.
This interface should not be implemented by user-defined classes. Code that
wants to create an instance implementing this interface should use the
methods provided by ChannelAccessValueFactory
instead.

ChannelAccessAlarmOnlyShort asReadOnlyValue()
Returns a read-only version of this value. If the value is read-only, this value is returned. Otherwise, a wrapped version of this value, that does not allow modifications is returned.
Please note that the read-only value is not a copy of this value, but just a wrapper around it. This means, that modifications of the wrapped value will result in modifications of the read-only value. Therefore it is bad practice to modify a value that has been used as the base for a read-only value, because code that still has a reference to the read-only value might not expect this change and thus fail unexpectedly.

).ChannelAccessAlarmOnlyShort clone()
Creates and returns a copy of this object. The object returned is completely independent from this object. This means that modifications to this object will not affect the returned object and vice-versa.
The object returned is guaranteed to be completely identical to this
object, including its type. This means that
x.clone().equals(x)
and
x.clone().getClass() == x.getClass()
are always
true
.
The returned value is guaranteed to allow write access, even if this value is read-only. This means that cloning a read-only value is a good way to get a writable copy.
