GeometryShapeConverter (Morphia)

java.lang.Object
- dev.morphia.converters.TypeConverter
- - dev.morphia.geo.GeometryShapeConverter

All Implemented Interfaces:

SimpleValueConverter

Direct Known Subclasses:

GeometryShapeConverter.LineStringConverter, GeometryShapeConverter.MultiLineStringConverter, GeometryShapeConverter.MultiPointConverter, GeometryShapeConverter.MultiPolygonConverter, GeometryShapeConverter.PointConverter, GeometryShapeConverter.PolygonConverter
```
public class GeometryShapeConverter
extends TypeConverter
implements SimpleValueConverter
```
Converter that understands most Geometry instances are effectively just lists of either other geometry objects or double coordinates. Recursively encodes and decodes Geometry objects, but needs to be instantiated with a List of GeometryFactory instances that represented the hierarchy of Geometries that make up the required Geometry object.
Overridden by subclasses to define exact behaviour for specific Geometry concrete classes.

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`static class`	`GeometryShapeConverter.LineStringConverter`	Defines a new LineStringConverter.
`static class`	`GeometryShapeConverter.MultiLineStringConverter`	Defines a new MultiLineStringConverter.
`static class`	`GeometryShapeConverter.MultiPointConverter`	Defines a new MultiPointConverter.
`static class`	`GeometryShapeConverter.MultiPolygonConverter`	Extends and therefore configures GeometryShapeConverter to provide the specific configuration for converting MultiPolygon objects to and from MongoDB representations of the GeoJson.

- Method Detail
  - decode
```
public Geometry decode(java.lang.Class<?> targetClass,
                       java.lang.Object fromDBObject,
                       MappedField optionalExtraInfo)
```
    Description copied from class: TypeConverter
    
    decode the DBObject and provide the corresponding java (type-safe) object
    NOTE: optionalExtraInfo might be null
    
    Specified by:
    
    decode in class TypeConverter
    
    Parameters:
    
    targetClass - the class to create and populate
    
    fromDBObject - the DBObject to use when populating the new instance
    
    optionalExtraInfo - the MappedField that contains the metadata useful for decoding
    
    Returns:
    
    the new instance
  - encode
```
public java.lang.Object encode(java.lang.Object value,
                               MappedField optionalExtraInfo)
```
    Description copied from class: TypeConverter
    
    encode the (type-safe) java object into the corresponding DBObject
    
    Overrides:
    
    encode in class TypeConverter
    
    Parameters:
    
    value - The object to encode
    
    optionalExtraInfo - the MappedField that contains the metadata useful for decoding
    
    Returns:
    
    the encoded version of the object
