Usage

From source file:gda.spring.propertyeditors.RealVectorPropertyEditor.java

@Override
public void setAsText(String text) throws IllegalArgumentException {
    if (StringUtils.hasText(text)) {
        try {/* w w w .  ja  v  a  2  s . com*/
            // remove spaces
            text = text.replace(" ", "");

            // remove leading/trailing braces
            text = text.replace("{", "").replace("}", "");

            String[] valueStrings = text.split(",");
            double[] values = new double[valueStrings.length];
            for (int j = 0; j < valueStrings.length; j++) {
                values[j] = Double.valueOf(valueStrings[j]);
            }

            RealVector vector = MatrixUtils.createRealVector(values);
            setValue(vector);
        } catch (Throwable e) {
            throw new IllegalArgumentException(
                    "Could not convert " + StringUtils.quote(text) + " to a RealVector", e);
        }
    } else {
        setValue(null);
