    • close

      public void close() throws IOException
      Description copied from class: Writer
      Close the stream, flushing it first. Once a stream has been closed, further write() or flush() invocations will cause an IOException to be thrown. Closing a previously-closed stream, however, has no effect.
      Specified by:
      close in interface java.lang.AutoCloseable
      Specified by:
      close in class Writer
      Throws:
      IOException

    • flush

      public void flush() throws IOException
      Description copied from class: Writer
      Flush the stream. If the stream has saved any characters from the various write() methods in a buffer, write them immediately to their intended destination. Then, if that destination is another character or byte stream, flush it. Thus one flush() invocation will flush all the buffers in a chain of Writers and OutputStreams.
      Specified by:
      flush in class Writer
      Throws:
      IOException

    • write

      public void write(char[] cbuf, int off, int len) throws IOException
      Description copied from class: Writer
      Write a portion of an array of characters.
      Specified by:
      write in class Writer
      Throws:
      IOException

    • write

      public void write(java.lang.String str, int off, int len) throws IOException
      Description copied from class: Writer
      Write a portion of a string.
      Overrides:
      write in class Writer
      Throws:
      IOException

    • write

      public void write(int c) throws IOException
      Description copied from class: Writer
      Write a single character. The character to be written is contained in the 16 low-order bits of the given integer value; the 16 high-order bits are ignored. Subclasses that intend to support efficient single-character output should override this method.
      Overrides:
      write in class Writer
      Throws:
      IOException

    • write

      public void write(java.lang.String str) throws IOException
      Description copied from class: Writer
      Write a string.
      Overrides:
      write in class Writer
      Throws:
      IOException

    • write

      public void write(char[] cbuf) throws IOException
      Description copied from class: Writer
      Write an array of characters.
      Overrides:
      write in class Writer
      Throws:
      IOException

    • toString

      public java.lang.String toString()
      Description copied from class: Object
      Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: getClass().getName() + '@' + Integer.toHexString(hashCode())
      Overrides:
      toString in class Object
