- use allocator class to wrap the stream pointers instead of passing
them into ISstream, OSstream and using a dynamic cast to delete
then. This is especially important if we will have a bidirectional
stream (can't delete twice!).
STYLE:
- file stream constructors with std::string (C++11)
- for rewind, explicit about in|out direction. This is not currently
important, but avoids surprises with any future bidirectional access.
- combined string streams in StringStream.H header.
Similar to <sstream> include that has both input and output string
streams.
Previously Fstreams had stdStream() as a public member and the other
streams had stream() as a protected member.
All serial streams now have public method stdStream() and the stream()
method has been eliminated. This is not only more consistent, but also
avoids confusion (for the programmer, not the compiler) with the
ITstream::stream() method.
- token class handles both single and double quoted strings. Single quoted
strings are used to tag regular expressions. At the moment this is just
syntactical sugar and isn't (yet) treated differently than double-quoted
strings.
- write output for std:string, with/without single quotes with the method
writeQuoted(). Use distinct method name to avoid inadvertent compiler
conversions.
- write wordRe and keyType using writeQuoted()
- Istream and Ostream now retain backslashes when reading/writing strings.
The previous implementation simply discarded them, except when used to
escape a double-quote or a newline. It is now vitally important to retain
them, eg for quoting regular expression meta-characters.
The backslash continues to be used as an escape character for double-quote
and newline, but otherwise get passed through "as-is" without any other
special meaning (ie, they are *NOT* C-style strings). This helps avoid
'backslash hell'!
For example,
string: "match real dots \.+, question mark \? or any char .*"
C-style: "match real dots \\.+, question mark \\? or any char .*"
- combined subfiles in db/IOstreams, some had more copyright info than code
- OPstreamI.H contained only private methods, moved into OPstream.C
Are these really correct?
IOstreams/Istream.H:# include "HashTable.C"
token/token.H:#define NoHashTableC
