java.lang.Object

org.opends.server.replication.plugin.HistoricalCsnRangeMatchingRuleImpl

All Implemented Interfaces:

MatchingRuleImpl

public final class HistoricalCsnRangeMatchingRuleImpl
extends Object
implements MatchingRuleImpl

Extensible matching rule to allow a range search on CSNs for a given replica.

It uses the same index as HistoricalCsnOrderingMatchingRuleImpl, but emulates a range search on a multivalued attribute. We can do that because the index is ordered by replica id and we're interested on a range search for a single replica only.

Method Summary

Modifier and Type	Method	Description
Collection<? extends Indexer>	createIndexers(Schema schema, IndexingOptions options)	Returns the indexers for this matching rule.
Assertion	getAssertion(Schema schema, ByteSequence assertionValue)	Retrieves the normalized form of the provided assertion value, which is best suited for efficiently performing less than matching operations on that value.
MatchingRule.MatchingRuleType	getType()	Returns the type of this matching rule.
ByteString	normalizeAttributeValue(Schema schema, ByteSequence value)	Retrieves the normalized form of the provided attribute value, which is best suited for efficiently performing matching operations on that value.

public HistoricalCsnRangeMatchingRuleImpl()

Method Detail

getType

public MatchingRule.MatchingRuleType getType()

Description copied from interface: MatchingRuleImpl

Returns the type of this matching rule.

Specified by:

getType in interface MatchingRuleImpl

Returns:

the type of this matching rule.

getAssertion

public Assertion getAssertion(Schema schema,
                              ByteSequence assertionValue)
                       throws DecodeException

Description copied from interface: MatchingRuleImpl

Retrieves the normalized form of the provided assertion value, which is best suited for efficiently performing less than matching operations on that value. The assertion value is guaranteed to be valid against this matching rule's assertion syntax.

Specified by:

getAssertion in interface MatchingRuleImpl

Parameters:

schema - The schema in which this matching rule is defined.

assertionValue - The syntax checked assertion value to be normalized.

Returns:

The normalized version of the provided assertion value.

Throws:

DecodeException - if an syntax error occurred while parsing the value.

normalizeAttributeValue

public ByteString normalizeAttributeValue(Schema schema,
                                          ByteSequence value)
                                   throws DecodeException

Description copied from interface: MatchingRuleImpl

Retrieves the normalized form of the provided attribute value, which is best suited for efficiently performing matching operations on that value. Equality and ordering matching rules should return a normalized representation which can be compared with other normalized values using ByteSequence.equals(Object) and ByteSequence.compareTo(ByteSequence).

Specified by:

normalizeAttributeValue in interface MatchingRuleImpl

Parameters:

schema - The schema in which this matching rule is defined.

value - The attribute value to be normalized.

Returns:

The normalized version of the provided attribute value.

Throws:

DecodeException - If an syntax error occurred while parsing the value.

createIndexers

public Collection<? extends Indexer> createIndexers(Schema schema,
                                                    IndexingOptions options)

Description copied from interface: MatchingRuleImpl

Returns the indexers for this matching rule.

Specified by:

createIndexers in interface MatchingRuleImpl

Parameters:

schema - The schema in which this matching rule is defined.

options - The indexing options.

Returns:

a non null collection of indexers for this matching rule.
