Class GeometryDeserializer<T>

java.lang.Object
com.fasterxml.jackson.databind.JsonDeserializer<T>
com.fasterxml.jackson.databind.deser.std.StdDeserializer<T>
synapse.util.deserializers.GeometryDeserializer<T>
Type Parameters:
T - the type of WPILib geometry object to deserialize
All Implemented Interfaces:
com.fasterxml.jackson.databind.deser.NullValueProvider, com.fasterxml.jackson.databind.deser.ValueInstantiator.Gettable, Serializable
public class GeometryDeserializer<T> extends com.fasterxml.jackson.databind.deser.std.StdDeserializer<T>
Generic deserializer for WPILib geometry classes such as Translation2d, Rotation2d, Pose2d, Transform2d, and their 3D counterparts.

This deserializer expects a JSON object with:

  • "type": the simple class name of the geometry type (e.g., "Translation2d")
  • "value": an array of numeric components used to construct the geometry object

Example JSON: 

 {
   "type": "Translation2d",
   "value": [1.0, 2.0]
 }

      public GeometryDeserializer(Class<T> targetClass)
      Constructs a GeometryDeserializer for a specific WPILib geometry type.

      public T deserialize(com.fasterxml.jackson.core.JsonParser p, com.fasterxml.jackson.databind.DeserializationContext ctxt) throws IOException
      Deserializes a JSON object into the target WPILib geometry type.

      The JSON must contain both a "type" field matching the class name of the target geometry type and a "value" array of numeric components.

      Specified by:
      deserialize in class com.fasterxml.jackson.databind.JsonDeserializer<T>
      Parameters:
      p - the JsonParser instance providing the JSON data
      ctxt - the deserialization context
      Returns:
      an instance of the target geometry type populated with values from JSON
      Throws:
      IOException - if there is a problem reading from the parser
      IllegalArgumentException - if the JSON type does not match the target class
