Hi,
Double is a wrapper class for the double primitive type.
For more information, see:
http://java.sun.com/docs/books/tutorial/java/data/numberclasses.html
You have something like:
_data[j] =
Double.valueOf(inputValue.getElement(i).toString()).doubleValue();
You could do something like:
_data[j] = Double.valueOf(inputValue.getElement(i).toString());
However, this does use the type system very effectively. Are you sure
you want data[j] to be of type Double? If it was of type Token,
then your class could pass it as an output. If you want performance,
you could call this actor ArrayDoubleColumn and have the array be
double _data[j].
Take a look at the ptolemy/actor/lib/Array*.java classes for ideas.

Hi,
As you said, i am using the Double class to parse the string but i get
following error messages,
compile:
[javac] Compiling 1 source file to
/SFS/users/turuncu/progs/cvs/kepler/build/classes
[javac]
/SFS/users/turuncu/progs/cvs/kepler/build/src/edu/tutorial/turuncu/ArrayCol
umn.java:114:
incompatible types
[javac] found : double
[javac] required: java.lang.Double
[javac] _data[j] =
Double.valueOf(inputValue.getElement(i).toString()).doubleValue();
[javac]
^
[javac] 1 error
the inputValue variable is ArrayToken type and _data is in Double array
type. Double.valueOf expect a String argument but it is not working in
this way. I study sume examples that use Double.valueOf method in
Ptolemy actor directory but in my case i am not using stringTokenizer.
thank you again for your help
best regrads,
ufuk
