2017-08-29Make some CPDF_StreamContentParser methods static.Lei Zhang
For methods that are only exposed for testing. Once they are static, there is no need for dummy CPDF_StreamContentParser constructor calls in the unit tests. Adjust the CPDF_StreamContentParser constructor now that one of the parameters can no longer be a nullptr.

2017-08-23Convert string Find methods to return an OptionalRyan Harrison
The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.

2017-08-02Rewrite how string Insert() methods handle out of bound indicesRyan Harrison
The existing behaviour was to clamp the provided index to the valid bounds. This would lead to programming errors being hidden, since inserting would still do something even if the index calculation was wrong. The behaviour of these methods has been changed to instead early return when this occurs, returning the old length value. The caller can check if the call to Insert actually did anything by comparing the returned value to the length before calling insert. All of the existing calls to Insert have been tested by running all of the tests with asserts in the Insert method to check the index is in bounds. Additionally the call sites have been manually inspected. The majority of them are of the form Insert(0, foo) and the rest tend to be in a loop advancing from 0 to length. Convenience methods InsertAtFront/InsertAtBack have been added to handle calling Insert when the intent is for the character to be added to the beginning or end of the string. Existing call sites to Insert that do this have been converted. This work was originally being performed to check if there would be any issues in these methods with making FX_STRSIZE unsigned.
