      $schema in interface Qualified

    • $traverse

      public final <R> R $traverse(Traverser<?,R> traverser)
      Description copied from interface: QueryPart
      Traverser this QueryPart expression tree using a composable Traverser, producing a result.

      This offers a generic way to traverse expression trees to translate the tree to arbitrary other data structures. The simplest traversal would just count all the tree elements: 

      
 int count = CUSTOMER.NAME.eq(1).$traverse(0, (i, p) -> i + 1);

      The same can be achieved by translating the JDK Collector API to the Traverser API using Traversers.collecting(Collector). 

      
 CUSTOMER.NAME.eq(1).$traverse(Traversers.collecting(Collectors.counting()));

      Unlike a Collector, a Traverser is optimised for tree traversal, not stream traversal:

      • Is not designed for parallelism
      • It can Traverser.abort() traversal early when the result can be produced early (e.g. when running Traversers.containing(QueryPart), and a result has been found).
      • It can decide whether to Traverser.recurse() into a QueryPart subtree, or whether that is not necessary or even undesirable, e.g. to prevent entering new subquery scopes.
      • Unlike a Collector, which can use its Collector.accumulator() to accumulate each element only once, in tree traversal, it's desirable to be able to distinguish between accumulating an item Traverser.before() or Traverser.after() recursing into it. This is useful e.g. to wrap each tree node in XML opening and closing tags.

      This is a commercial jOOQ edition only feature.

      Specified by:
      $traverse in interface QueryPart

    • $replace

      public final QueryPart $replace(Replacer replacer)
      Description copied from interface: QueryPart
      Traverse a QueryPart hierarchy and recursively replace its elements by alternatives.

      While replacing contents, this QueryPart isn't modified. Instead, a new object is returned.

      This is a commercial jOOQ edition only feature.

      Specified by:
      $replace in interface QueryPart

    • getName

      public final String getName()

      The unqualified name of this object.
      Specified by:
      getName in interface Named

    • getQualifiedName

      public Name getQualifiedName()
      Description copied from interface: Named
      The qualified name of this object.
      Specified by:
      getQualifiedName in interface Named

    • getUnqualifiedName

      public final Name getUnqualifiedName()

      Specified by:
      getUnqualifiedName in interface Named

    • getComment

      public final String getComment()
      Description copied from interface: Named
      The comment on this object.

      This is the same as calling Named.getCommentPart() and then Comment.getComment().

      Specified by:
      getComment in interface Named

    • getCommentPart

      public final Comment getCommentPart()
      Description copied from interface: Named
      The comment on this object as a QueryPart.
      Specified by:
      getCommentPart in interface Named

    • hashCode

      public int hashCode()
      Description copied from interface: QueryPart
      Generate a hash code from this QueryPart.

      In general, QueryPart hash codes are the same as the hash codes generated from QueryPart.toString(). This guarantees consistent behaviour with QueryPart.equals(Object)

      Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.

      Specified by:
      hashCode in interface QueryPart
      Returns:
      The QueryPart hash code

    • equals

      public boolean equals(Object that)
      Description copied from interface: QueryPart
      Check whether this QueryPart can be considered equal to another QueryPart.

      In general, QueryPart equality is defined in terms of QueryPart.toString() equality. In other words, two query parts are considered equal if their rendered SQL (with inlined bind variables) is equal. This means that the two query parts do not necessarily have to be of the same type.

      Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.

      Specified by:
      equals in interface QueryPart
      Parameters:
      that - The other QueryPart
      Returns:
      Whether the two query parts are equal

    • $name

      public final Name $name()
      Description copied from interface: Named
      Experimental query object model accessor method, see also QOM. Subject to change in future jOOQ versions, use at your own risk.
      Specified by:
      $name in interface Named

    • clauses

      @Deprecated public Clause[] clauses(Context<?> ctx)
      Deprecated.
      - 3.11.0 - [#8179] - This functionality will be removed in the future.
      Description copied from interface: QueryPartInternal
      The Clauses that are represented by this query part.

      QueryParts can specify several Clauses for which an event will be emitted before (in forward order) and after (in reverse order) visiting the the query part through Context.visit(QueryPart)

      This method is for JOOQ INTERNAL USE only. Do not reference directly

      Specified by:
      clauses in interface QueryPartInternal
      Returns:
      The Clauses represented by this query part or null or an empty array if this query part does not represent a clause.

    • toString

      public String toString()
      Description copied from interface: QueryPart
      Render a SQL string representation of this QueryPart.

      For improved debugging, this renders a SQL string of this QueryPart with inlined bind variables. If this QueryPart is Attachable, then the attached Configuration may be used for rendering the SQL string, including SQLDialect and Settings. Do note that most QueryPart instances are not attached to a Configuration, and thus there is no guarantee that the SQL string will make sense in the context of a specific database.

      Specified by:
      toString in interface QueryPart
      Overrides:
      toString in class Object
      Returns:
      A SQL string representation of this QueryPart
