Class AbstractOrderingMatchingRuleImpl

java.lang.Object

org.forgerock.opendj.ldap.schema.AbstractOrderingMatchingRuleImpl

All Implemented Interfaces:

MatchingRuleImpl

public abstract class AbstractOrderingMatchingRuleImpl
extends Object

This class implements a default ordering matching rule that matches normalized values in byte order.

The getXXXAssertion() methods are default implementations which assume that the assertion syntax is the same as the attribute syntax. Override them if this assumption does not hold true.

Constructor Details

AbstractOrderingMatchingRuleImpl

protected AbstractOrderingMatchingRuleImpl(String indexId)

Creates an instance of the ordering matching rule.

Parameters:

indexId - the identifier of the DB index

Method Details

getType

public MatchingRule.MatchingRuleType getType()

Description copied from interface: MatchingRuleImpl

Returns the type of this matching rule.

Returns:

the type of this matching rule.

getAssertion

public final Assertion getAssertion(Schema schema,
 ByteString value)
                             throws DecodeException

Description copied from interface: MatchingRuleImpl

Compiles the provided assertion value as an Assertion suitable for use with equalityMatch, approxMatch and extensibleMatch search filters.

Parameters:

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

value - The assertion value.

Returns:

The compiled assertion.

Throws:

DecodeException - If the assertion value does not conform to the matching rule's assertion syntax.

getOrderingAssertion

public Assertion getOrderingAssertion(Schema schema,
 ByteString lower,
 ByteString upper,
 boolean lowerIncluded,
 boolean upperIncluded)
                               throws DecodeException

Description copied from interface: MatchingRuleImpl

Compiles the provided ordering assertion value range as an Assertion suitable for use with ordering search filters, including greaterOrEqual and lessOrEqual.

Parameters:

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

lower - The lower bound assertion value, or null if there is no lower bound and the range will start from the smallest key.

upper - The upper bound assertion value to be normalized, or null if there is no upper bound and the range will end at the largest key.

lowerIncluded - true if a key exactly matching the lower bound is included in the range, false if only keys strictly greater than the lower bound are included. This value is ignored if the lower bound is not specified.

upperIncluded - true if a key exactly matching the upper bound is included in the range, false if only keys strictly less than the upper bound are included. This value is ignored if the upper bound is not specified.

Returns:

The compiled ordering assertion.

Throws:

DecodeException - If the upper or lower bounds do not conform to the matching rule's assertion syntax or if the matching rule does not support ordering matching.

createIndexers

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

Description copied from interface: MatchingRuleImpl

Returns the indexers for this matching rule.

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.
