### Question:
SharedObjectSyncUtil { public synchronized void deletePartitionSchema( PartitionSchema removed ) { synchronizeTransformations( true, transMeta -> transMeta.getPartitionSchemas().remove( removed ) ); } SharedObjectSyncUtil( Spoon spoon ); synchronized void synchronizeConnections( DatabaseMeta database ); synchronized void synchronizeConnections( DatabaseMeta database, String originalName ); synchronized void synchronizeSlaveServers( SlaveServer slaveServer ); synchronized void synchronizeSlaveServers( SlaveServer slaveServer, String originalName ); synchronized void deleteSlaveServer( SlaveServer removed ); synchronized void deleteClusterSchema( ClusterSchema removed ); synchronized void deletePartitionSchema( PartitionSchema removed ); synchronized void reloadTransformationRepositoryObjects( boolean includeActive ); synchronized void reloadJobRepositoryObjects( boolean includeActive ); synchronized void reloadSharedObjects(); synchronized void synchronizeClusterSchemas( ClusterSchema clusterSchema ); synchronized void synchronizeClusterSchemas( ClusterSchema clusterSchema, String originalName ); synchronized void synchronizePartitionSchemas( PartitionSchema partitionSchema ); synchronized void synchronizePartitionSchemas( PartitionSchema partitionSchema, String originalName ); synchronized void synchronizeSteps( StepMeta step ); synchronized void synchronizeSteps( StepMeta step, String originalName );  }### Answer:
