    • 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
      Overrides:
      append in class java.io.Writer

    • 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
      Overrides:
      append in class java.io.Writer

    • 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.

      Specified by:
      append in interface Appendable
      Overrides:
      append in class java.io.Writer
