Uses of OptionDescriber in org.apache.accumulo.core.iterators

Classes in org.apache.accumulo.core.iterators that implement OptionDescriber

Modifier and Type	Class	Description
class	Combiner	A SortedKeyValueIterator that combines the Values for different versions (timestamp) of a Key within a row into a single Value.
class	DebugIterator
class	Filter	A SortedKeyValueIterator that filters entries from its source iterator.
class	FirstEntryInRowIterator
class	LongCombiner	A TypedValueCombiner that translates each Value to a Long before reducing, then encodes the reduced Long back to a Value.
class	OrIterator	An iterator that provides a sorted-iteration of column qualifiers for a set of column families in a row.
class	SortedKeyIterator
class	TypedValueCombiner<V>	A Combiner that decodes each Value to type V before reducing, then encodes the result of typedReduce back to Value.

Uses of OptionDescriber in org.apache.accumulo.core.iterators.user

Classes in org.apache.accumulo.core.iterators.user that implement OptionDescriber

Modifier and Type	Class	Description
class	AgeOffFilter	A filter that ages off key/value pairs based on the Key's timestamp.
class	BigDecimalCombiner	A family of combiners that treat values as BigDecimals, encoding and decoding using the built-in BigDecimal String input/output functions.
static class	BigDecimalCombiner.BigDecimalMaxCombiner
static class	BigDecimalCombiner.BigDecimalMinCombiner
static class	BigDecimalCombiner.BigDecimalSummingCombiner
class	CfCqSliceFilter	Filters key/value pairs for a range of column families and a range of column qualifiers.
class	CfCqSliceSeekingFilter	Filters key/value pairs for a range of column families and a range of column qualifiers.
class	ColumnAgeOffFilter	A filter that ages off key/value pairs based on the Key's column and timestamp.
class	ColumnSliceFilter
class	GrepIterator	This iterator provides exact string matching of the term specified by the "term" option.
class	LargeRowFilter	This iterator suppresses rows that exceed a specified number of columns.
class	MaxCombiner	A Combiner that interprets Values as Longs and returns the largest Long among them.
class	MinCombiner	A Combiner that interprets Values as Longs and returns the smallest Long among them.
class	RegExFilter	A Filter that matches entries based on Java regular expressions.
class	ReqVisFilter	A Filter that matches entries with a non-empty ColumnVisibility.
class	RowEncodingIterator	The RowEncodingIterator is designed to provide row-isolation so that queries see mutations as atomic.
class	SummingArrayCombiner	A Combiner that interprets Values as arrays of Longs and returns an array of element-wise sums.
class	SummingCombiner	A Combiner that interprets Values as Longs and returns their sum.
class	TimestampFilter	A Filter that matches entries whose timestamps fall within a range.
class	TransformingIterator	The TransformingIterator allows portions of a key (except for the row) to be transformed.
class	VersioningIterator
class	VisibilityFilter	A SortedKeyValueIterator that filters based on ColumnVisibility.
class	WholeColumnFamilyIterator	The WholeColumnFamilyIterator is designed to provide row/cf-isolation so that queries see mutations as atomic.
class	WholeRowIterator	The WholeRowIterator is designed to provide row-isolation so that queries see mutations as atomic.
