* Speed up ScopedPrimitiveArrayROMathieu Chartier2015-09-111-7/+19

The speedup comes from the fact that GetArrayRegion doesn't need to allocate a copy of array.

* Don't need swap anymore.Dan Albert2014-11-051-10/+0
| | | | | | | | | | | The declaration of std::swap here is inconsistent with the one in libc++ (noexcept differences). Rather than worrying about keeping them all consistent, just remove swap. It was only ever added for ART, and ART now uses std::unique_ptr instead. This was causing an ambiguous overload error in system/core. Change-Id: I4cf4c41c5dda01a96915e8309af2f8be089d1a2a

| * Scoped primitive arrays: allow them to be nullKenny Root2013-05-171-0/+12
| | | | | | | | | | | | | | | | | | | | | | Sometimes there is a pattern where you may have an optional argument to a JNI call. Instead of throwing NullPointerException which would be done on required arguments, let the programmer create the scoped array and reset it to the value if it's determined later that the argument was provided. This eliminates the need to handle raw primitive array objects and the chance that they will accidentally leaked. Change-Id: Ic701b33e710b292ff9a63e75c7b763f4ce71e011
