Java Source Code / Java Documentation » Database Client » SQL Workbench » workbench.util   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    workbench.util.FileUtil FileUtil public class FileUtil (Code) author:    support@sql-workbench.net Method Summary public static  void closeQuitely(Closeable c)      public static  void closeStreams(List<Closeable> streams)      public static  long copy(InputStream in, OutputStream out)      Copies the content of the InputStream to the OutputStream. final public static  long estimateRecords(File f)      final public static  long estimateRecords(File f, long sampleLines)      Tries to estimate the number of records in the given file. public static  long getCharacterLength(File source, String encoding)      Returns the number of characters according to the encoding in the specified file. final public static  String getLineEnding(Reader in)      Try to detect the line ending used by the passed Reader. This will advance the reader until a line ending is found. The reader will not be closed Parameters:   in - the "file" to test the sequence of characters used as the line ending (e.g. public static  Collection<String> getLines(BufferedReader in)      Read the lines of the given Reader into a Collection. public static  byte[] readBytes(InputStream in)      Read the content of the InputStream into a ByteArray. public static  String readCharacters(Reader in)      Read the content of the Reader into a String. final public static  int readLines(BufferedReader in, StringBuilder buffer, int numLines, String lineEnd)      Read the contents of the Reader into the provided StringBuilder. Max. Method Detail closeQuitely public static void closeQuitely(Closeable c)(Code) Closes a Closeable without throwing any errors Parameters:   c - the Closeable to close closeStreams public static void closeStreams(List<Closeable> streams)(Code) copy public static long copy(InputStream in, OutputStream out) throws IOException(Code) Copies the content of the InputStream to the OutputStream. Both streams are closed automatically. estimateRecords final public static long estimateRecords(File f) throws IOException(Code) estimateRecords final public static long estimateRecords(File f, long sampleLines) throws IOException(Code) Tries to estimate the number of records in the given file. This is done by reading the first sampleLines records of the file and assuming the average size of an row in the first lines is close to the average row in the complete file. getCharacterLength public static long getCharacterLength(File source, String encoding) throws IOException(Code) Returns the number of characters according to the encoding in the specified file. For single-byte encodings this should be identical to source.length() For large files this might take some time! Parameters:   source - the (text) file to check Parameters:   encoding - the encoding of the text file the number of characters (not bytes) in the file getLineEnding final public static String getLineEnding(Reader in) throws IOException(Code) Try to detect the line ending used by the passed Reader. This will advance the reader until a line ending is found. The reader will not be closed Parameters:   in - the "file" to test the sequence of characters used as the line ending (e.g. \n or \r\n) throws:   java.io.IOException - getLines public static Collection<String> getLines(BufferedReader in)(Code) Read the lines of the given Reader into a Collection. The Reader will be closed after all lines have been read. Parameters:   in - the "file" to read a Collection with all the lines in the file readBytes public static byte[] readBytes(InputStream in) throws IOException(Code) Read the content of the InputStream into a ByteArray. The InputStream is closed automatically. readCharacters public static String readCharacters(Reader in) throws IOException(Code) Read the content of the Reader into a String. The Reader is closed automatically. readLines final public static int readLines(BufferedReader in, StringBuilder buffer, int numLines, String lineEnd) throws IOException(Code) Read the contents of the Reader into the provided StringBuilder. Max. numLines lines are read. The Reader will not be closed Parameters:   in - the Reader to be used Parameters:   buffer - the StringBuilder to received the lines Parameters:   numLines - the max. number of lines to be read Parameters:   lineEnd - the lineEnding to be used the number of lines read Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
