com.streambase.sb.operator.parameter.SBSimpleBeanInfo

All Implemented Interfaces:

SBBeanInfo, BeanInfo

public abstract class SBSimpleBeanInfo
extends SimpleBeanInfo
implements SBBeanInfo

SimpleBeanInfo subclass used by StreamBase operators and adapters to provide the set of properties available by the operator or adapter. SBSimpleBeanInfo should be used instead of SimpleBeanInfo to allow StreamBase to identify the name of missing getter or setter methods for a specific property.

Since:

7.0
