Method Detail

openOutputStream

public OutputStream openOutputStream()
                              throws IOException

Opens an output stream to write to the file. This writes to memory. This clears any existing output in the file.

Specified by:

Overrides:

openOutputStream in class SimpleJavaFileObject

Returns:

an output stream.

Throws:

IOException - if an I/O error occurs.

openInputStream

public InputStream openInputStream()
                            throws IOException

Opens an input stream to the file data. If the file has never been written the input stream will contain no data (i.e. length=0).

Specified by:

openInputStream in interface FileObject

Overrides:

openInputStream in class SimpleJavaFileObject

Returns:

an input stream.

Throws:
