public class ExpressionWriter
- extends LineWriter
This actor reads input tokens and writes them, one line at a time,
to a specified file. The format it uses is that generated by the
toString() method of the token, which for most tokens is an expression
that can be read back in using ExpressionReader. String tokens, for
example, include the enclosing quotation marks in the output.
If you do not want the enclosing quotation marks, use LineWriter.
The file is specified by the fileName attribute
using any form acceptable to FileParameter.
If the append attribute has value true,
then the file will be appended to. If it has value false,
then if the file exists, the user will be queried for permission
to overwrite, and if granted, the file will be overwritten.
If the confirmOverwrite parameter has value false,
then this actor will overwrite the specified file if it exists
without asking. If true (the default), then if the file
exists, then this actor will ask for confirmation before overwriting.

ExpressionWriter
public ExpressionWriter(CompositeEntity container,
java.lang.String name)
throws IllegalActionException,
NameDuplicationException
- Construct an actor with the given container and name.
- Parameters:
container - The container.name - The name of this actor.
- Throws:
IllegalActionException - If the actor cannot be contained
by the proposed container.
NameDuplicationException - If the container already has an
actor with this name.
_writeToken
protected void _writeToken(Token token)
- Write the specified token to the current writer using the toString()
method of the token, which usually results in an expression that
can be read back in using the expression parser.
- Overrides:
_writeToken in class LineWriter
- Parameters:
token - The token to write.
