040bae34d7 Allowing instance creators to be registered with the raw type only (without specifying type parameters). 2012-10-24 20:40:44 +00:00

af4879dbb7 Move interceptors from 'alpha' to 'extras'.
This makes the feature less risky to use! It now uses our
TypeAdapterFactory infrastructure rather than relying on
parallel infrastructure.

c25278b4d6 Created an alpha package that holds experimental feature.
Added support for JsonPostDeserializer that allows you to invoke postDeserialize methods on an Gson deserialized object.

2fef83799d Optimizations and bug fixes for LinkedHashTreeMap.
The most interesting optimization is to replace ArrayDeque with a manual linked list that reuses the nodes 'parent' field. These optimizations save about 20%.

aceadaecf1 Add a hashing layer to LinkedTreeMap. Instead of having 1 root node, the class now has several root nodes, one for each hash bucket in a hash table.
Compared to LinkedTreeMap, this is slower for small (size=5) maps: 124% slower to get() and 33% slower to create and populate. It's a win for large (size=500) maps: 46% faster to get() but 8% slower to create and populate. And it's a big win for very large (size=50,000) maps: 81% faster to get() and 46% faster to create and populate.

I'm going to follow this up with some simple optimizations: caching local fields and simplifying access. That should narrow the performance gap.

a0493b9732 New code that can split an AVL tree into two AVL trees.
This is in preparation for a new feature where LinkedTreeMap will have multiple roots, each in its own hash bucket.

a6ab854302 Fix a bug where we were unlinking nodes that shouldn't have been unlinked.

93e38901df Draft of LinkedTreeMap. Its ordered like a LinkedHashMap but it doesn't do any hashing for DoS resistance.
Not yet adopted in our code.

Known critical bugs:
 - throws ClassCastException when get() is called with a non-comparable key
 - throws NullPointerException on get(null)

085856c128 Don't leave the JsonReader in an invalid state if nextInt(), nextDouble() or nextLong() fails. We now save a reference to the string before we parse it, and keep that referenced value if parsing fails. 2012-08-26 22:06:57 +00:00

46b4346505 Get JsonReader2 to the point that it's passing most tests.
Still missing: 
 - non-execute prefixes
 - rolling back 'pos' when a double fails to parse
 - octal prefix failures

c5c65ba626 Add an experimental rewrite of JsonReader.
The motivating difference is that JsonReaderV2 tries to read each character at most once. This means that when it reads literals, it also attempts to decode them to a keyword (true/false/null) or a number.

This change also _doesn't_ read strings until demanded to do so. This should permit streaming access to strings down the road.

This code is not yet complete, nor is has it been properly optimized. And the implementation is also quite a mess! It is a work in progress.

2c8bec27d4 Permit multiple top-level values in JsonWriter in lenient mode. Also fix some cases where we don't throw the right thing on a closed JsonWriter.
I'd prefer to not support multiple top-level values, but we support it in JsonReader and it's easier to be consistent. Kevin Hayen's patch pointed me in the right direction here, but I needed to do more work to cover some of the edge cases.

Fixes issue 397.
