All Superinterfaces:

RowOperation, RowState

All Known Implementing Classes:

GraphRowReader

public interface RowReader
extends RowOperation

Provides access to the operational, configuration and other state information required for read operations on a single graph row.

Acts as a single component within a TableReader container and encapsulates the HBase client Get operation for use in read operations across multiple logical entities within a graph row.
