Class FilterListAssembler

java.lang.Object

org.cloudgraph.hbase.filter.FilterListAssembler

All Implemented Interfaces:

Assembler, HBaseFilterAssembler

Direct Known Subclasses:

BinaryPrefixColumnFilterAssembler, GraphFetchColumnFilterAssembler, InitialFetchColumnFilterAssembler, StatefullBinaryPrefixColumnFilterAssembler

public abstract class FilterListAssembler
extends Object
implements HBaseFilterAssembler

Supports assembly of HBase filter lists.

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.
