    - ### Methods inherited from class java.lang.Object

      `getClass, notify, notifyAll, toString, wait, wait, wait`

- - ### Constructor Detail

    - #### Feature

          public Feature​(FeatureDefn feature_def)

      Constructor.

      Note that the Feature will increment the reference count of its defining FeatureDefn.

      Parameters:
        `feature_def` - feature class (layer) definition to which the feature will adhere.

  - ### Method Detail

    - #### delete

          public void delete​()

      Delete (in memory) a feature.

      Calling this method is not required as normal garbage collection will reclaim associated resources when the object goes out of scope. Otherwise calling delete() explicitly will help release resources sooner. Don't call any method on a deleted object !

    - #### equals

          public boolean equals​(java.lang.Object obj)

      Overrides:
        `equals` in class `java.lang.Object`

    - #### hashCode

          public int hashCode​()

      Overrides:
        `hashCode` in class `java.lang.Object`

    - #### clone

          public java.lang.Object clone​()

      Overrides:
        `clone` in class `java.lang.Object`

    - #### GetDefnRef

          public FeatureDefn GetDefnRef​()

    - #### SetGeometry

          public int SetGeometry​(Geometry geom)

      Set feature geometry.

      This method updates the features geometry, and operate exactly as SetGeometryDirectly(), except that this method does not assume ownership of the passed geometry, but instead makes a copy of it.

      Parameters:
        `geom` - new geometry to apply to feature. Passing null value here is correct and it will result in deallocation of currently assigned geometry without assigning new one.
      Returns:
        0 if successful, or throws a RuntimeException (or an error code if DontUseExceptions() has been called) if the geometry type is illegal for the FeatureDefn (checking not yet implemented).

    - #### SetGeometryDirectly

          public int SetGeometryDirectly​(Geometry geom)

      Set feature geometry.

      This method updates the features geometry, and operate exactly as SetGeometry(), except that this method assumes ownership of the passed geometry.

      Parameters:
        `geom` - new geometry to apply to feature. Passing null value here is correct and it will result in deallocation of currently assigned geometry without assigning new one.
      Returns:
        0 if successful, or throws a RuntimeException (or an error code if DontUseExceptions() has been called) if the geometry type is illegal for the FeatureDefn (checking not yet implemented).

    - #### GetGeometryRef

          public Geometry GetGeometryRef​()

      Fetch pointer to feature geometry.

    - #### SetFrom

          public int SetFrom​(Feature srcFeature,
                             int forgiving)

      Set one feature from another.

      Overwrite the contents of this feature from the geometry and attributes of another. The srcFeature does not need to have the same FeatureDefn. Field values are copied by corresponding field names. Field types do not have to exactly match. SetField() method conversion rules will be applied as needed.

      Parameters:
        `srcFeature` - the feature from which geometry, and field values will be copied.
        `forgiving` - 1 if the operation should continue despite lacking output fields matching some of the source fields.
      Returns:
        0 if the operation succeeds, even if some values are not transferred, otherwise throws a RuntimeException (or an error code if DontUseExceptions() has been called).

    - #### SetFrom

          public int SetFrom​(Feature srcFeature)

      Set one feature from another.

      Same as below with forgiving == 1

      Since:
        Java bindings 1.7.0
      See Also:
        `SetFrom(Feature srcFeature, int forgiving)`

    - #### SetFromWithMap

          public int SetFromWithMap​(Feature srcFeature,
                                    int forgiving,
                                    int[] map)

      Set one feature from another.

      Overwrite the contents of this feature from the geometry and attributes of another. The hOtherFeature does not need to have the same OGRFeatureDefn. Field values are copied according to the provided indices map. Field types do not have to exactly match. SetField() function conversion rules will be applied as needed. This is more efficient than SetFrom(Feature, int) in that this doesn't lookup the fields by their names. Particularly useful when the field names don't match.

      Parameters:
        `srcFeature` - the feature from which geometry, and field values will be copied.
        `forgiving` - 1 if the operation should continue despite lacking output fields matching some of the source fields.
        `map` - Array of the indices of the destination feature's fields stored at the corresponding index of the source feature's fields. A value of -1 should be used to ignore the source's field. The array should not be null and be as long as the number of fields in the source feature.
      Returns:
        0 if the operation succeeds, even if some values are not transferred, otherwise throws a RuntimeException (or an error code if DontUseExceptions() has been called).
