| Method Summary | |
| public static boolean | compareFileDates(Date date1, Date date2)
For some reason modification milliseconds for some files are unstable,
use this function to compare file dates ignoring milliseconds. | | public static boolean | compareFiles(File file1, File file2)
Compares two files for directories/files synchronization purposes. | | public static void | copyFile(File src, File dest)
Copies one file, existing file will be overridden. | | public static void | copyFolder(File src, File dest)
| | public static void | copyFolder(File src, File dest, boolean recursive)
| | public static void | copyFolder(File src, File dest, boolean recursive, boolean onlyNew)
Copies folder. | | public static void | copyFolder(File src, File dest, boolean recursive, boolean onlyNew, FileFilter filter)
Copies folder. | | public static void | copyStream(InputStream in, OutputStream out, int bufferSize)
Copies streams. | | public static boolean | emptyFolder(File folder)
Recursively deletes whole content of the given folder. | | public static URL | file2url(File file)
Utility method to convert a
File object to a local URL. | | public static InputStream | getResourceInputStream(URL url)
Opens input stream for given resource. | | public static boolean | isResourceExists(URL url)
Checks if resource exist and can be opened. | | public static void | synchronizeFolders(File src, File dest)
Performs one-way directories synchronization comparing files only,
not folders. | | public static void | synchronizeFolders(File src, File dest, FileFilter filter)
Performs one-way directories synchronization comparing files only,
not folders. | | public static File | url2file(URL url)
Utility method to convert local URL to a
File object. |
| compareFileDates | | public static boolean compareFileDates(Date date1, Date date2)(Code) | | For some reason modification milliseconds for some files are unstable,
use this function to compare file dates ignoring milliseconds.
Parameters:
date1 - first file modification date
Parameters:
date2 - second file modification date true if files modification dates are equal ignoringmilliseconds |
| compareFiles | | public static boolean compareFiles(File file1, File file2)(Code) | | Compares two files for directories/files synchronization purposes.
Parameters:
file1 - one file to compare
Parameters:
file2 - another file to compare true if file names are equal (case sensitive), fileshave equal lengths and modification dates (milliseconds ignored)

| copyFile | | public static void copyFile(File src, File dest) throws IOException(Code) | | Copies one file, existing file will be overridden.
Parameters:
src - source file to copy FROM
Parameters:
dest - destination file to copy TO
throws:
IOException - if any I/O error has occurred |
| copyFolder | | public static void copyFolder(File src, File dest) throws IOException(Code) | | Copies folder recursively, existing files will be overridden
Parameters:
src - source folder
Parameters:
dest - target folder
throws:
IOException - if any I/O error has occurred |
| copyFolder | | public static void copyFolder(File src, File dest, boolean recursive) throws IOException(Code) | | Copies folder, existing files will be overridden
Parameters:
src - source folder
Parameters:
dest - target folder
Parameters:
recursive - if true, processes folder recursively
throws:
IOException - if any I/O error has occurred |
| copyFolder | | public static void copyFolder(File src, File dest, boolean recursive, boolean onlyNew) throws IOException(Code) | | Copies folder.
Parameters:
src - source folder
Parameters:
dest - target folder
Parameters:
recursive - if true, processes folder recursively
Parameters:
onlyNew - if true, target file will be overridden if itis older than source file only
throws:
IOException - if any I/O error has occurred |
| copyFolder | | public static void copyFolder(File src, File dest, boolean recursive, boolean onlyNew, FileFilter filter) throws IOException(Code) | | Copies folder.
Parameters:
src - source folder
Parameters:
dest - target folder
Parameters:
recursive - if true, processes folder recursively
Parameters:
onlyNew - if true, target file will be overridden if itis older than source file only
Parameters:
filter - file filter, optional, if null all files willbe copied
throws:
IOException - if any I/O error has occurred |
| copyStream | | public static void copyStream(InputStream in, OutputStream out, int bufferSize) throws IOException(Code) | | Copies streams.
Parameters:
in - source stream
Parameters:
out - destination stream
Parameters:
bufferSize - buffer size to use
throws:
IOException - if any I/O error has occurred |
| emptyFolder | | public static boolean emptyFolder(File folder)(Code) | | Recursively deletes whole content of the given folder.
Parameters:
folder - folder to be emptied true if given folder becomes empty or not exists |
| getResourceInputStream | | public static InputStream getResourceInputStream(URL url) throws IOException(Code) | | Opens input stream for given resource. This method behaves differently
for different URL types:
- for local files it returns buffered file input stream;
- for local JAR files it reads resource content into memory
buffer and returns byte array input stream that wraps those
buffer (this prevents locking JAR file);
- for common URL's this method simply opens stream to that URL
using standard URL API.
It is not recommended to use this method for big resources within JAR
files.
Parameters:
url - resource URL input stream for given resource
throws:
IOException - if any I/O error has occurred |
| isResourceExists | | public static boolean isResourceExists(URL url)(Code) | | Checks if resource exist and can be opened.
Parameters:
url - absolute URL which points to a resource to be checked true if given URL points to an existing resource |
| synchronizeFolders | | public static void synchronizeFolders(File src, File dest, FileFilter filter) throws IOException(Code) | | Performs one-way directories synchronization comparing files only,
not folders.
Parameters:
src - source folder
Parameters:
dest - target folder
Parameters:
filter - file filter, optional, if null all files willbe included into synchronization process
throws:
IOException - if any I/O error has occurred

| url2file | | public static File url2file(URL url)(Code) | | Utility method to convert local URL to a
File object.
Parameters:
url - an URL file object for given URL or null if URL is notlocal |
