Examples with ServerRegionFunctionExecutor org.apache.geode.internal.cache.execute.ServerRegionFunctionExecutor used on opensource projects

Example 1 with ServerRegionFunctionExecutor

use of org.apache.geode.internal.cache.execute.ServerRegionFunctionExecutor in project geode by apache.

the class FunctionServiceManager method onRegion.

/**
   * Returns an {@link Execution} object that can be used to execute a data dependent function on
   * the specified Region.<br>
   * When invoked from a GemFire client, the method returns an Execution instance that sends a
   * message to one of the connected servers as specified by the {@link Pool} for the region. <br>
   * Depending on the filters setup on the {@link Execution}, the function is executed on all
   * GemFire members that define the data region, or a subset of members.
   * {@link Execution#withFilter(Set)}).
   * 
   * For DistributedRegions with DataPolicy.NORMAL, it throws UnsupportedOperationException. For
   * DistributedRegions with DataPolicy.EMPTY, execute the function on any random member which has
   * DataPolicy.REPLICATE <br>
   * . For DistributedRegions with DataPolicy.REPLICATE, execute the function locally. For Regions
   * with DataPolicy.PARTITION, it executes on members where the data resides as specified by the
   * filter.
   * 
   * @return Execution
   * @throws FunctionException if the region passed in is null
   * @since GemFire 6.0
