* Add the Truth dependency
* Port Junit test to Truth in the package `com.google.gson` of the module `gson`
* Replace the `assertThat(e.getMessage()).isEqualTo(...)"` with `assertThat(e).hasMessageThat().isEqualTo(...)`
* Minor fixes
* Add Gson.fromJson(..., TypeToken) overloads
Previously only Gson.fromJson(..., Type) existed which is however not
type-safe since the generic type parameter T used for the return type is
not bound.
Since these methods are often used in the form
gson.fromJson(..., new TypeToken<...>(){}.getType())
this commit now adds overloads which accept a TypeToken and are therefore
more type-safe.
Additional changes:
- Fixed some grammar mistakes
- Added javadoc @see tags
- Consistently write "JSON" in uppercase
- More precise placement of @SuppressWarnings("unchecked")
* Add to Gson.fromJson javadoc that JSON is fully consumed
The newly added documentation deliberately does not state which exception
is thrown because Gson.assertFullConsumption could throw either a
JsonIOException or a JsonSyntaxException.
* Remove unnecessary wrapping and unwrapping as TypeToken in Gson.fromJson
Since the actual implementation of Gson.fromJson is TypeToken based, the
TypeToken variant overloads are now the "main" implementation and the other
overloads delegate to them.
Previously the Type variant overloads were the "main" implementation which
caused `TypeToken.getType()` followed by `TypeToken.get(...)` when the
TypeToken variant overloads were used.
* Trim source code whitespaces
* Fix Gson.fromJson(JsonReader, Class) not casting read Object
To be consistent with the other Gson.fromJson(..., Class) overloads the
method should cast the result.
* Replace User Guide link in Gson documentation
* Remove more references to fromJson(..., Type)
* Extend documentation for fromJson(JsonReader, ...)
* Replace some TypeToken.getType() usages
* Address feedback; improve documentation
* Remove fromJson(JsonReader, Class) again
As noticed during review adding this method is source incompatible.
Consolidated all of the different code paths that we use to construct instances. We now have an ObjectConstructor class that knows what type it constructs; this means that we don't need to ever do reflection to lookup a constructor at construction time.
Cleaned up some buggy type adapters, particularly around handling of null.
Removed dead code for object graph navigation.
Moved some classes into 'internal' so they are visible to the 'bind' subpackage.
Turned some TypeAdapterFactory/TypeAdapter pairs inside out so that the TypeAdapter is now the inner class. This is necessary so that the factories can take parameters.
Added an API to request the 'next' type adapter for a type. This allows type adapters to compose other type adapters. We're using this in two places:
- where the user has excluded a type from serialization but not deserialization, we need to use the "default" deserialization but interpose null on serialization. We create a type adapter that delegates for one and returns null for the other.
- similarly when a DOM type serializer is registered but no deserializer, or vice versa.
This is the biggest change to the MiniGson core.
For backwards compatibility, return null for the empty string.
Simplify JsonSerializationContext/JsonDeserializationContext to simply call through to GSON. SerializeDefault is currently unsupported.
More useful error messages when calling getAsBoolean on a JsonNull.
Remove currently unused MemoryRefStack. We might need this back again, though wiring it back in will be much more difficult because we don't interject ourselves between the users' various type adapters.
