In a collection of ID values.

  • Constructor Details

    • IdInExpression

      public IdInExpression(Collection<?> idCollection)

  • Method Details

    • idValues

      public Collection<Object> idValues()
      Description copied from interface: IdInCommon
      Return the ids this expression is looking to fetch.
      Specified by:
      idValues in interface IdInCommon

    • removeIds

      public int removeIds(Set<Object> hitIds)
      Description copied from interface: IdInCommon
      Remove Ids that where obtained from l2 cache. Don't fetch these from DB.
      Specified by:
      removeIds in interface IdInCommon

    • prepareExpression

      public void prepareExpression(BeanQueryRequest<?> request)
      Description copied from interface: SpiExpression
      Prepare the expression. For example, compile sub-query expressions etc.
      Specified by:
      prepareExpression in interface SpiExpression

    • containsMany

      public void containsMany(BeanDescriptor<?> desc, ManyWhereJoins manyWhereJoin)
      Description copied from interface: SpiExpression
      Process "Many" properties populating ManyWhereJoins.

      Predicates on Many properties require an extra independent join clause.

      Specified by:
      containsMany in interface SpiExpression

    • validate

      public void validate(SpiExpressionValidation validation)
      Description copied from interface: SpiExpression
      Validate all the properties/paths associated with this expression.
      Specified by:
      validate in interface SpiExpression

    • addBindValues

      public void addBindValues(SpiExpressionBind request)
      Description copied from interface: SpiExpression
      Add the parameter values to be set against query. For each ? place holder there should be a corresponding value that is added to the bindList.
      Specified by:
      addBindValues in interface SpiExpression
      Parameters:
      request - the associated request.

    • addSqlNoAlias

      public void addSqlNoAlias(SpiExpressionRequest request)
      For use with deleting non-attached detail beans during stateless update.

    • addSql

      public void addSql(SpiExpressionRequest request)
      Description copied from interface: SpiExpression
      Add some sql to the query.

      This will contain ? as a place holder for each associated bind values.

      The 'sql' added to the query can contain object property names rather than db tables and columns. This 'sql' is later parsed converting the logical property names to their full database column names.

      Specified by:
      addSql in interface SpiExpression
      Parameters:
      request - the associated request.

    • queryPlanHash

      public void queryPlanHash(StringBuilder builder)
      Incorporates the number of ID values to bind.
      Specified by:
      queryPlanHash in interface SpiExpression

    • queryBindKey

      public void queryBindKey(BindValuesKey key)
      Description copied from interface: SpiExpression
      Build the key for bind values of the query.
      Specified by:
      queryBindKey in interface SpiExpression

    • isSameByBind

      public boolean isSameByBind(SpiExpression other)
      Description copied from interface: SpiExpression
      Return true if the expression is the same with respect to bind values.
