Syntax
public class ConditionalProcessor : AbstractProcessor, IEntryProcessor, IPortableObject
Remarks

If the underlying filter expects to evaluate existent entries only (i.e. entries for which IsPresent is true, it should be combined with a PresentFilter as follows:

IFilter filterPresent = new AndFilter(new PresentFilter(), filter);

Constructors

ConditionalProcessor()

Default constructor.

Declaration
public ConditionalProcessor()

ConditionalProcessor(IFilter, IEntryProcessor)

Construct a ConditionalProcessor for the specified filter and the processor.

Declaration
public ConditionalProcessor(IFilter filter, IEntryProcessor processor)
Parameters
Type Name Description
IFilter filter

The filter.
IEntryProcessor processor

The entry processor.
Remarks

The specified entry processor gets invoked if and only if the filter applied to the IInvocableCacheEntry evaluates to true; otherwize the result of the Process(IInvocableCacheEntry) invocation will return null.

Fields

Declaration
protected IFilter m_filter
Field Value
Type Description
IFilter

m_processor

The underlying entry processor.

Declaration
protected IEntryProcessor m_processor
Field Value

Declaration
public override bool Equals(object o)
Parameters
Type Name Description
object o

Returns
Type Description
bool

true iff this ConditionalProcessor and the passed object are equivalent ConditionalProcessors.
Overrides

Parameters
Type Name Description
IInvocableCacheEntry entry

The IInvocableCacheEntry to process.
Returns
Type Description
object

Parameters
Type Name Description
ICollection entries

A read-only collection of IInvocableCacheEntry objects to process.
Returns
Type Description
