  • Method Details

    • 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 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(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(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 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

    • getBuffer

      public StringBuffer getBuffer()

    • append

      public StringWriter append(char c)
      Description copied from interface: Appendable

      Appends the specified character.

      Parameters
      • c: the character to append.
      Returns

      this Appendable.

      Throws
      • IOException: if an I/O error occurs.
      Specified by:
      append in interface Appendable

    • append

      public StringWriter append(CharSequence csq)
      Description copied from interface: Appendable

      Appends the character sequence csq. Implementation classes may not append the whole sequence, for example if the target is a buffer with limited size.

      If csq is null, the characters "null" are appended.

      Parameters
      • csq: the character sequence to append.
      Returns

      this Appendable.

      Throws
      • IOException: if an I/O error occurs.
      Specified by:
      append in interface Appendable

    • append

      public StringWriter append(CharSequence csq, int start, int end)
      Description copied from interface: Appendable

      Appends a subsequence of csq.

      If csq is not null then calling this method is equivalent to calling append(csq.subSequence(start, end)).

      If csq is null, the characters "null" are appended.

      Parameters

      • csq: the character sequence to append.

      • start: @param start the first index of the subsequence of csq that is appended.

      • end: @param end the last index of the subsequence of csq that is appended.

      Returns

      this Appendable.

      Throws

      • IndexOutOfBoundsException: @throws IndexOutOfBoundsException if start end or end is greater than the length of csq.

      • IOException: if an I/O error occurs.
