readEntirely
public static java.lang.String readEntirely(java.io.BufferedReader in) throws java.io.IOException
Reads the whole BufferedReader line by line, using \n as line separator for each line.Note that this method will add a final \n to the last line even though there is no new line character at the end of last line in the original reader.
The BufferedReader is closed when this method returns.
- Parameters:
in
- theBufferedReader
to read from- Returns:
- a String with the whole content read from the
BufferedReader
- Throws:
java.io.IOException
- if an IO problems occur during reading
-
readEntirely
public static java.lang.String readEntirely(java.io.File f) throws java.io.IOException
Reads the entire content of the file and returns it as a String.- Parameters:
f
- the file to read from- Returns:
- a String with the file content
- Throws:
java.io.IOException
- if an IO problems occurs during reading
-
readEntirely
public static java.lang.String readEntirely(java.io.InputStream is) throws java.io.IOException
Reads the entire content of theInputStream
and returns it as a String.The input stream is closed when this method returns.
- Parameters:
is
- theInputStream
to read from- Returns:
- a String with the input stream content
- Throws:
java.io.IOException
- if an IO problems occurs during reading
-
concat
public static java.lang.String concat(java.lang.String dir, java.lang.String file)
-
forceDelete
public static boolean forceDelete(java.io.File file)
Recursively delete file- Parameters:
file
- the file to delete- Returns:
- true if the deletion completed successfully (ie if the file does not exist on the filesystem after this call), false if a deletion was not performed successfully.
-
getPathFiles
public static java.util.List getPathFiles(java.io.File root, java.io.File file)
Returns a list of Files composed of all directories being parent of file and child of root + file and root themselves. Example: getPathFiles(new File("test"), new File("test/dir1/dir2/file.txt")) => {new File("test/dir1"), new File("test/dir1/dir2"), new File("test/dir1/dir2/file.txt") } Note that if root is not an ancester of file, or if root is null, all directories from the file system root will be returned.
-
listAll
public static java.util.Collection listAll(java.io.File dir, java.util.Collection ignore)
Returns a collection of all Files being contained in the given directory, recursively, including directories.- Parameters:
dir
- The directory from which all files, including files in subdirectory) are extracted.ignore
- a Collection of filenames which must be excluded from listing- Returns:
- A collectoin containing all the files of the given directory and it's subdirectories.
-
resolveFile
public static java.io.File resolveFile(java.io.File file, java.lang.String filename)
-
normalize
public static java.io.File normalize(java.lang.String path)
"Normalize" the given absolute path.This includes:
- Uppercase the drive letter if there is one.
- Remove redundant slashes after the drive spec.
- Resolve all ./, .\, ../ and ..\ sequences.
- DOS style paths that start with a drive letter will have \ as the separator.
File.getCanonicalPath()
this method specifically does not resolve symbolic links.- Parameters:
path
- the path to be normalized.- Returns:
- the normalized version of the path.
- Throws:
java.lang.NullPointerException
- if path is null.
