From 71b593e88b1e601db84cd3c399865a0bfd8164cf Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Thu, 21 Jul 2016 16:49:02 -0400 Subject: MAINT-6584: Streamline static LLImageJ2C implementation API. Specifically, remove unused function pointer types CreateLLImageJ2CFunction, DestroyLLImageJ2CFunction and EngineInfoLLImageJ2CFunction. Also eliminate static fallbackDestroyLLImageJ2CImpl() and fallbackEngineInfoLLImageJ2CImpl(), leaving only static fallbackCreateLLImageJ2CImpl(). We do need a factory function to instantiate the appropriate LLImageJ2CImpl subclass, so leave the fallbackCreateLLImageJ2CImpl() link seam in place. However, given that every known LLImageJ2CImpl subclass is cheap to instantiate, make getEngineInfo() a pure virtual method on that subclass: the static LLImageJ2C::getEngineInfo() method can temporarily construct an instance to query. While we're at it, make getEngineInfo() return std::string like LLImageJ2C::getEngineInfo(). It's ridiculous that fallbackEngineInfoLLImageJ2CImpl() implementations constructed a static std::string and returned its c_str(), only to have LLImageJ2C::getEngineInfo() construct ANOTHER std::string from the returned const char*. fallbackDestroyLLImageJ2CImpl() never did anything useful: it merely deleted the passed LLImageJ2CImpl subclass pointer as the specific subclass type. But since LLImageJ2CImpl's destructor is virtual, LLImageJ2C's destructor could simply delete the stored LLImageJ2CImpl*. In fact, make mImpl a boost::scoped_ptr so we don't even have to delete it manually. --- indra/llimagej2coj/llimagej2coj.cpp | 15 ++++----------- 1 file changed, 4 insertions(+), 11 deletions(-) (limited to 'indra/llimagej2coj/llimagej2coj.cpp') diff --git a/indra/llimagej2coj/llimagej2coj.cpp b/indra/llimagej2coj/llimagej2coj.cpp index e98f677d9b..0152b879c2 100644 --- a/indra/llimagej2coj/llimagej2coj.cpp +++ b/indra/llimagej2coj/llimagej2coj.cpp @@ -33,23 +33,16 @@ #include "lltimer.h" //#include "llmemory.h" -const char* fallbackEngineInfoLLImageJ2CImpl() -{ - static std::string version_string = - std::string("OpenJPEG: " OPENJPEG_VERSION ", Runtime: ") - + opj_version(); - return version_string.c_str(); -} - +// Factory function: see declaration in llimagej2c.cpp LLImageJ2CImpl* fallbackCreateLLImageJ2CImpl() { return new LLImageJ2COJ(); } -void fallbackDestroyLLImageJ2CImpl(LLImageJ2CImpl* impl) +std::string LLImageJ2COJ::getEngineInfo() const { - delete impl; - impl = NULL; + return std::string("OpenJPEG: " OPENJPEG_VERSION ", Runtime: ") + + opj_version(); } // Return string from message, eliminating final \n if present -- cgit v1.2.3
