From d14787e49777888eb7c685c0d5803044e7b7971a Mon Sep 17 00:00:00 2001 From: Daniel Dunbar Date: Wed, 19 Aug 2009 18:40:58 +0000 Subject: Change raw_svector_ostream to reserve the input buffer if necessary, Ted was right. - This class turns out to be much more convenient to use if we do this; clients can make sure the buffer is always big enough if they care (since our current idiom tends to be to use a SmallString<256> for the input to this we should generally be avoiding an unnecessary malloc). Also, add a convenience raw_svector_ostream::str method which flushes the buffer and returns a StringRef for the vector contents. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79446 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Support/raw_ostream.h | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'include/llvm') diff --git a/include/llvm/Support/raw_ostream.h b/include/llvm/Support/raw_ostream.h index ed06dbf..dc496d4 100644 --- a/include/llvm/Support/raw_ostream.h +++ b/include/llvm/Support/raw_ostream.h @@ -454,10 +454,14 @@ class raw_svector_ostream : public raw_ostream { public: /// Construct a new raw_svector_ostream. /// - /// \arg O - The vector to write to; this *must* have at least 128 bytes of - /// free space in it. + /// \arg O - The vector to write to; this should generally have at least 128 + /// bytes free to avoid any extraneous memory overhead. explicit raw_svector_ostream(SmallVectorImpl &O); ~raw_svector_ostream(); + + /// str - Flushes the stream contents to the target vector and return a + /// StringRef for the vector contents. + StringRef str(); }; /// raw_null_ostream - A raw_ostream that discards all output. -- cgit v1.1
