Classes
| Class |
Description |
| BadConnectionCheck |
Represents an error where deserialization tried to connect two connections that were not compatible. |
| DeserializationError |
|
| MissingBlockType |
Represents an error where the serialized state is expected to provide a block type, but it is not provided. |
| MissingConnection |
Represents an error where deserialization encountered a block that did not have a connection that was defined in the serialized state. |
| RealChildOfShadow |
Represents an error where deserialization encountered a real block as it was deserializing children of a shadow. This is an error because it is an invariant of Blockly that shadow blocks do not have real children. |
| UnregisteredIcon |
