Description

I just created IO-139 for a StringBuilder Writer implementation that requies JDK 1.5. So I thought I would look at the impact on IO of 1) Removing all deprecations and 2) Making appropriate JDK 1.5 changes (generics, using StringBuilder and new Appendable for Writers). Below is a summary, thought it could be a starting point for discussion about IO 2.0

1) DEPRECATIONS

• CopyUtils
• FileCleaner
• WildcardFilter
• FileSystemUtils freeSpace(String)
• IOUtils toByteArray(String), toString(byte[]), toString(byte[], String)

2) JDK 1.5

• ConditionalFileFilter List (and also AndFileFilter and OrFileFilter implementations
• getFileFilters() and setFileFilters() use generic List<IOFileFilter>
• Constructor for NameFileFilter, PrefixFileFilter, SuffixFileFilter, WildcardFileFilter use generic List<String>
• replace StringBuffer with StringBuilder where appropriate (FilenameUtils, FileSystemUtils, HexDump,IOUtils
• FileUtils
• convertFileCollectionToFileArray() --> Collection<File>
• listFiles() --> Collection<File>
• listFiles() --> Collection<File>
• writeStringToFile String-->CharSequence (JDK 1.4+)
• ProxyReader - add read(CharBuffer)
• IOUtils
• readLines(Reader) return List<String>
• toInputStream(String) --> toInputStream(CharSequence) (JDK 1.4+)
• write(String data, OutputStream) and write(StringBuffer data, OutputStream) --> write(CharSequence data, OutputStream)
• write(String, Writer) and write(StringBuffer, Writer) --> write(CharSequence data, Writer)
• LineIterator Iterator --> Iterator<String
• NullWriter - add "Appendable" methods
• ProxyWriter - add "Appendable" methods
