Interface MatchingRuleImpl

All Known Implementing Classes:
AbstractOrderingMatchingRuleImpl, HistoricalCsnOrderingMatchingRuleImpl, HistoricalCsnRangeMatchingRuleImpl
public interface MatchingRuleImpl
This interface defines the set of methods that must be implemented to define a new matching rule.

  • Method Details

    • getType

      MatchingRule.MatchingRuleType getType()
      Returns the type of this matching rule.
      Returns:
      the type of this matching rule.

    • getAssertion

      Assertion getAssertion(Schema schema, ByteString assertionValue) throws DecodeException
      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.
      assertionValue - The assertion value.
      Returns:
      The compiled assertion.
      Throws:
      DecodeException - If the assertion value does not conform to the matching rule's assertion syntax.

    • getSubstringAssertion

      default Assertion getSubstringAssertion(Schema schema, ByteString subInitial, List<ByteString> subAnyElements, ByteString subFinal) throws DecodeException
      Compiles the provided substring assertion fragments as an Assertion suitable for use with substrings search filters.
      Parameters:
      schema - The schema in which this matching rule is defined.
      subInitial - The substring value fragment that should appear at the beginning of the target value.
      subAnyElements - The substring value fragments that should appear in the middle of the target value.
      subFinal - The substring value fragment that should appear at the end of the target value.
      Returns:
      The compiled substring assertion.
      Throws:
      DecodeException - If the assertion value fragments do not conform to the matching rule's assertion syntax or if the matching rule does not support substring matching.

    • getOrderingAssertion

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

    • normalizeAttributeValue

      ByteString normalizeAttributeValue(Schema schema, ByteString value) throws DecodeException
      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 ByteString.equals(Object) and ByteString.compareTo(ByteString).
      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

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