Class AbstractBounds

AbstractBounds
All Implemented Interfaces:
Bounds
Direct Known Subclasses:
GeneralBounds

public abstract class AbstractBounds extends Object implements Bounds
Base class for envelope implementations. This base class provides default implementations for toString(), equals(java.lang.Object) and hashCode() methods.

This class do not holds any state. The decision to implement Serializable or org.geotools.util.Cloneable interfaces is left to implementors.

  • Constructor Details

    • AbstractBounds

      protected AbstractBounds()
      Constructs an envelope.
  • Method Details

    • getLowerCorner

      public Position getLowerCorner()
      A coordinate position consisting of all the minimal ordinates. The default implementation returns a direct position backed by this envelope, so changes in this envelope will be immediately reflected in the direct position.
      Specified by:
      getLowerCorner in interface Bounds
      Returns:
      The lower corner.
    • getUpperCorner

      public Position getUpperCorner()
      A coordinate position consisting of all the maximal ordinates. The default implementation returns a direct position backed by this envelope, so changes in this envelope will be immediately reflected in the direct position.
      Specified by:
      getUpperCorner in interface Bounds
      Returns:
      The upper corner.
    • toString

      public String toString()
      Returns a string representation of this envelope. The default implementation returns a string containing lower corner coordinates first, followed by upper corner coordinates. Other informations like the CRS or class name may or may not be presents at implementor choice.

      This string is okay for occasional formatting (for example for debugging purpose). But if there is a lot of envelopes to format, users will get more control by using their own instance of CoordinateFormat.

      Overrides:
      toString in class Object
    • hashCode

      public int hashCode()
      Returns a hash value for this envelope.
      Overrides:
      hashCode in class Object
    • equals

      public boolean equals(Object object)
      Returns true if the specified object is also an envelope with equals coordinates and CRS.
      Overrides:
      equals in class Object
      Parameters:
      object - The object to compare with this envelope.
      Returns:
      true if the given object is equals to this envelope.
