Class CustomCondition

  • All Implemented Interfaces:
    Serializable, Condition, QueryPart, QueryPartInternal

    public abstract class CustomCondition
    extends Object
    A base class for custom Condition implementations in client code.

    Client code may provide proper Condition implementations extending this useful base class. All necessary parts of the Condition interface are already implemented. Only this method needs further implementation: accept(Context).

    Refer to that methods' Javadoc for further details about their expected behaviour.

      • accept

        public abstract void accept​(Context<?> ctx)
        Subclasses must implement this method.
        This QueryPart can accept a Context object in order to render a SQL string or to bind its variables.
      • clauses

        public final Clause[] clauses​(Context<?> ctx)
        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.

      • 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
        Overrides:
        equals in class Object
        Parameters:
        that - The other QueryPart
        Returns:
        Whether the two query parts are equal
      • 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
        Overrides:
        hashCode in class Object
        Returns:
        The QueryPart hash code
      • 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
