## Class Writer

- - ### Methods Summary

    Methods
    Return type | Name and parameters
    --- | ---
    `Writer` | `leftShift(Object value)` Overloads the leftShift operator for Writer to allow an object to be written using Groovy's default representation for the object.
    `PrintWriter` | `newPrintWriter()` Create a new PrintWriter for this Writer.
    `Object` | `withPrintWriter(Closure closure)` Create a new PrintWriter for this Writer.
    `Object` | `withWriter(Closure closure)` Allows this writer to be used within the closure, ensuring that it is flushed and closed before this method returns.
    `void` | `write(Writable writable)` A helper method so that dynamic dispatch of the writer.write(object) method will always use the more efficient Writable.writeTo(writer) mechanism if the object implements the Writable interface.

- - ### Methods Detail

    - #### public Writer leftShift(Object value)

      Overloads the leftShift operator for Writer to allow an object to be written using Groovy's default representation for the object.

      Parameters:
        `value` - an Object whose default representation will be written to the Writer
      Returns:
        the writer on which this operation was invoked
      Since:
        1.0

    - #### public PrintWriter newPrintWriter()

      Create a new PrintWriter for this Writer.

      Returns:
        a PrintWriter
      Since:
        1.6.0

    - #### public Object withPrintWriter(Closure closure)

      Create a new PrintWriter for this Writer. The writer is passed to the closure, and will be closed before this method returns.

      Parameters:
        `closure` - the closure to invoke with the PrintWriter
      Returns:
        the value returned by the closure
      Since:
        1.6.0

    - #### public Object withWriter(Closure closure)

      Allows this writer to be used within the closure, ensuring that it is flushed and closed before this method returns.

      Parameters:
        `closure` - the closure that the writer is passed into
      Returns:
        the value returned by the closure
      Since:
        1.5.2

    - #### public void write(Writable writable)

      A helper method so that dynamic dispatch of the writer.write(object) method will always use the more efficient Writable.writeTo(writer) mechanism if the object implements the Writable interface.

      Parameters:
        `writable` - an object implementing the Writable interface
      Since:
        1.0
