[jira] Commented: (IO-140) IO 2.0 - Move to JDK 1.5

["Benjamin Bentmann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IO-140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12592303#action_12592303 ] 

Benjamin Bentmann commented on IO-140:
--------------------------------------

bq. Also to add @Deprecated to all deprecated methods (no idea why this is necessary)
Unlike the related javadoc tag, the annotation {{@Deprecated}} will be part of the bytecode and allows compilers to output deprecation warnings without access to sources/javadocs.

> 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
