Method Detail

getBase

public static URL getBase(URL url)

returns the path of the url without the last path component

readBytes

public static byte[] readBytes(URL url)
                        throws IOException

reads the content form an url into a ByteArray

Throws:

IOException

decode

public static String decode(String s,
                            String enc)
                     throws UnsupportedEncodingException

same as URLDecoder.decode(java.lang.String). But calls the deprecated method under 1.3.

Throws:

UnsupportedEncodingException

encode

public static String encode(String s,
                            String enc)
                     throws UnsupportedEncodingException

same as URLEncoder.encode(java.lang.String). But calls the deprecated method under 1.3.

Throws:

UnsupportedEncodingException

getInputStream

public static InputStream getInputStream(URL url)
                                  throws IOException

returns a BufferedInputStream from the url. If the url-protocol is "file" no url connection will be opened.

Throws:

IOException

getFileFrom

public static File getFileFrom(URL url)
                        throws IOException

Throws:

IOException

copy

public static void copy(String srcPath,
                        String destPath)
                 throws IOException

copies a file.

Parameters:

srcPath - the source-path. Thats the path of the file that should be copied.

destPath - the destination-path

Throws:

IOException

copy

public static void copy(String srcPath,
                        String destPath,
                        boolean onlyOverwriteIfNewer)
                 throws IOException

copies a file.

Parameters:

srcPath - the source-path. Thats the path of the file that should be copied.

destPath - the destination-path

Throws:

IOException

copy

public static void copy(File srcFile,
                        File destFile,
                        boolean onlyOverwriteIfNewer)
                 throws IOException

copies a file.

Throws:

IOException

copyStreams

public static void copyStreams(InputStream in,
                               OutputStream out)
                        throws IOException

copies the contents of the input stream to the output stream.

Parameters:

in -

out -

Throws:

IOException

getRelativePath

public static String getRelativePath(File base,
                                     File file)
                              throws IOException

returns the relative path of file to base.

Throws:

IOException - if position of file is not relative to base

getRelativeURL

public static String getRelativeURL(File base,
                                    File file)
                             throws IOException

returns the relative path of file to base. same as getRelativePath(File, File) but replaces windows-plattform-specific file separator \ with /

Throws:

IOException - if position of file is not relative to base

getJarFiles

public static File[] getJarFiles(String baseDir,
                                 String dirList)
