public class ConditionalProcessor
Conditional entry processor represents a processor that is invoked conditionally based on the result of an entry evaluation.
If the underlying filter expects to evaluate existent entries only (i.e. entries for whichisPresent()
is
true), it should be combined with a
PresentFilter
as follows:
Filter filterPresent = new AndFilter(new PresentFilter(), filter);
PresentFilter

protected Filter |
m_filter

ConditionalProcessor()
Default constructor (necessary for the ExternalizableLite interface). |
|
ConditionalProcessor(Filter filter,
InvocableMap.EntryProcessor processor)
Construct a ConditionalProcessor for the specified filter and the processor. |

public ConditionalProcessor()
public ConditionalProcessor(Filter filter, InvocableMap.EntryProcessor processor)
The specified entry processor gets invoked if and only if the filter
applied to the InvocableMap entry evaluates to true; otherwize the
result of the process(com.tangosol.util.InvocableMap.Entry)
invocation will return null.
