Class SBPropertyDescriptor.SingleValueSetter

java.lang.Object

com.streambase.sb.operator.parameter.SBPropertyDescriptor.Setter

com.streambase.sb.operator.parameter.SBPropertyDescriptor.SingleValueSetter

Enclosing class:

SBPropertyDescriptor

protected abstract static class SBPropertyDescriptor.SingleValueSetter
extends SBPropertyDescriptor.Setter

This abstract specialization of Setter assumes that the property type will have a single value (which currently accounts for all property types except string lists). It extracts the value of that parameter from the map and calls an abstract parse method on it.
