@Experimental public interface Param<P>
An easily extensible parameter that allows functional map operations to be tweaked. Examples would include local-only parameter, skip-cache-store parameter and others.What makes
Param
different fromMetaParam
is thatParam
values are never stored in the functional map. They merely act as ways to tweak how operations are executed.Since
Param
instances control how the internals work, onlyParam
implementations by Infinispan will be supported.This interface is equivalent to Infinispan's Flag, but it's more powerful because it allows to pass a flag along with a value. Infinispan's Flag are enum based which means no values can be passed along with value.
Since each param is an independent entity, it's easy to create public versus private parameter distinction. When parameters are stored in enums, it's more difficult to make such distinction.

Nested Classes Modifier and Type Interface Description static class
Param.ExecutionMode
Defines where is the command executed.static class
Param.LockingMode
Normally the cache has to acquire locks during any write operation to guarantee its correctness.static class
Param.PersistenceMode
When a persistence store is attached to a cache, by default all write operations, regardless of whether they are inserts, updates or removes, are persisted to the store.static class
Param.ReplicationMode
static class
Param.StatisticsMode
Defines how statistics are gathered for this command.

Method Detail
-
id
int id()
A parameter's identifier. Each parameter must have a different id.A numeric id makes it flexible enough to be stored in collections that take up low resources, such as arrays.

Parameter's value.
