2017-04-04RefCount CPDF_StreamAcc all the time.Tom Sepez
Pass stream argument to constructor; it feels like a stream accessor should always be made from a stream rather than passing one in after the fact.

2016-09-21Remove some objnum locals with AddIndirectObjecttsepez
Also, it's idempotent, so simplify some logic in callers to not care if objnum is zero. The alternate forms are rarely used, using the objnum form makes it clear that SetReferenceFor() can't possibly register the object as a side-effect. Review-Url: https://codereview.chromium.org/2361713002
2016-09-19Clean up CPDF_Stream.tsepez
Replace the CPDF_Stream(nullptr, 0, nullptr) pattern with a default ctor. Remove unused parameters from CPDF_Stream::SetData(). Both are always passed as FALSE. CPDF_Stream declared its own m_GenNum, which shadowed the one in CPDF_Object. It was used only to distinguish file/memory streams, so add a bool explicitly for this purpose. Remove the union, it would be sad if we confused user data with a C++ object with virtual function calls. Use unique_ptrs with appropriate deleters to manage memory.

2016-04-14Make CPDF_Dictionary methods take CFX_ByteString argumentstsepez
This will help avoid duplicate allocation of CFX_ByteStrings when the caller already has one. It may seem counter-intuitive that requiring the caller to pass an allocated CFX_ByteString rather than a static CFX_ByteStringC would improve the situation, but due to the idiosyncrasies of std::map, the CPDF_Dictionary methods must always do an allocation under the covers which can't be avoided. The changed callers in this CL are places where we would previously demote to CFX_ByteStringC and then allocate a a duplicate CFX_ByteString in the dictionary method.

2016-04-04Make down-conversion explicit from CFX_ByteString to CFX_ByteStringC.tsepez
Having this happen implicitly can be dangerous because the lifetime has to be considered; we should have caught the "red bots" in https://codereview.chromium.org/1847333004/#ps60001 at compile time. Review URL: https://codereview.chromium.org/1853233002
