    getValue()
     
    protected abstract PGboxbase
    newInstance()
    Obtain a new instance of a PGboxbase We could have used this.getClass().newInstance() here, but this forces us dealing with InstantiationException and IllegalAccessException.

    toString()
    Unlike geometries, toString() does _not_ contain the srid, as server-side PostGIS cannot parse this.

    • getPrefix

      public abstract String getPrefix()
      The Prefix we have in WKT rep. I use an abstract method here so we do not need to replicate the String object in every instance.
      Returns:
      the prefix, as a string

    • getPGtype

      public abstract String getPGtype()
      The Postgres type we have (same construct as getPrefix())
      Returns:
      String containing the name of the type for this box.

    • setValue

      public void setValue(String value) throws SQLException
      Overrides:
      setValue in class org.postgresql.util.PGobject
      Throws:
      SQLException

    • getValue

      public String getValue()
      Overrides:
      getValue in class org.postgresql.util.PGobject

    • toString

      public String toString()
      Unlike geometries, toString() does _not_ contain the srid, as server-side PostGIS cannot parse this.
      Overrides:
      toString in class org.postgresql.util.PGobject
      Returns:
      String representation of this box

    • getLLB

      public Point getLLB()
      Returns the lower left bottom corner of the box as a Point object
      Returns:
      lower left bottom corner of this box

    • getURT

      public Point getURT()
      Returns the upper right top corner of the box as a Point object
      Returns:
      upper right top corner of this box

    • equals

      public boolean equals(Object other)
      Overrides:
      equals in class org.postgresql.util.PGobject

    • compareLazyDim

      protected static boolean compareLazyDim(Point first, Point second)
      Compare two coordinates with lazy dimension checking. As the Server always returns Box3D with three dimensions, z==0 equals dimensions==2
      Parameters:
      first - First of two points to be compared
      second - Second of two points to be compared
      Returns:
      true if the points are the same, false otherwise

    • clone

      public Object clone()
      Overrides:
      clone in class org.postgresql.util.PGobject

    • newInstance

      protected abstract PGboxbase newInstance()
      Obtain a new instance of a PGboxbase We could have used this.getClass().newInstance() here, but this forces us dealing with InstantiationException and IllegalAccessException. Due to the PGObject.clone() brokennes that does not allow clone() to throw CloneNotSupportedException, we cannot even pass this exceptions down to callers in a sane way.
      Returns:
      a new instance of PGboxbase
