Easier way to exclude properties #450

Closed GoogleCodeExporter closed 9 years ago

Suggested way to exclude property from serializing/deserializing is the @Expose 
annotation, but when option 
GsonBuilder().excludeFieldsWithoutExposeAnnotation() is used I need to use 
@Expose on all fields I intend to serialize.

This is very annoying provided I have a big graph of data and only want to 
exclude one property.

Suggested way is to have an annotation @ExcludeFromGson that would always be 
read and properties marked with this annotation would not be 
serialized/deserialized.

}

GsonBuilder().setExclusionStrategies(new YourAnnotationExclusionStrategy(), ...
