Class BinaryPrefixColumnFilterAssembler

java.lang.Object

org.cloudgraph.hbase.filter.FilterListAssembler

org.cloudgraph.hbase.filter.BinaryPrefixColumnFilterAssembler

All Implemented Interfaces:

Assembler, HBaseFilterAssembler

public class BinaryPrefixColumnFilterAssembler
extends FilterListAssembler

Creates an HBase column filter list using QualifierFilter and BinaryPrefixComparator and recreating composite column qualifier prefixes for comparison using CompositeColumnKeyFactory.

HBase filters may be collected into lists using FilterList each with a MUST_PASS_ALL or MUST_PASS_ONE (logical) operator. Lists may then be assembled into hierarchies used to represent complex expression trees filtering either rows or columns in HBase.
