Modifier and Type	Class	Description
static final class	QueryPlan.Aggregator	Query plan node which applies aggregation.
static class	QueryPlan.Concat	Query plan node which represents a concatenated set of plans.
static final class	QueryPlan.DisjointUnion	Query plan node which represents a union set of plans, where each source plan only produces rows which aren't produced by the other sources.
static final class	QueryPlan.Empty	Query plan node which represents an empty set.
static final class	QueryPlan.Exists	Query plan node which only checks for the existance of at least one row.
static final class	QueryPlan.Filter	Query plan node which filters out rows.
static final class	QueryPlan.FullScan	Query plan node which scans all rows of a table.
static final class	QueryPlan.Grouper	Query plan node which applies grouping.
static final class	QueryPlan.GroupSort	Query plan node which sorts rows within a group.
static final class	QueryPlan.Identity	Query plan node which represents a single row with no columns.
static final class	QueryPlan.LoadOne	Query plan node which loads at most one row from a table.
static final class	QueryPlan.Mapper	Query plan node which applies custom row mapping and filtering.
static final class	QueryPlan.MergeConcat	Query plan node which represents a concatenated set of plans which have an explicit ordering, and source rows are compared to each other to maintain the ordering.
static final class	QueryPlan.MergeUnion	Query plan node which represents a union set of plans which have an common ordering, and rows are compared to each other for eliminating duplicates.
static class	QueryPlan.NaturalJoin	Query plan node which joins a target to a source based on a common set of columns.
static final class	QueryPlan.NestedLoopsJoin	Query plan node which represents a nested loop join.
static final class	QueryPlan.PrimaryJoin	Query plan node which joins index rows to primary rows.
static final class	QueryPlan.RangeScan	Query plan node which scans a range of rows from a table.
static final class	QueryPlan.RangeUnion	Query plan node which represents a union set of plans, where each source plan is limited to a range, and all sources produce rows in the same order.
static class	QueryPlan.Scan	Query plan node which scans a table.
static class	QueryPlan.Set	Query plan node which represents a set of plans.
static class	QueryPlan.Sort	Query plan node which sorts the rows.
static class	QueryPlan.Table	Query plan node which accesses rows from a table.
static class	QueryPlan.Union	Query plan node which represents a union set of plans.
