Date Thu, 10 Dec 2015 10:05:11 GMT

Jacob Saoumi updated SCXML-240:
-------------------------------
    Description: 
I need to extend the state model to have user-defined properties. For example:

<state id="xy" cs:type="myStateType"></state>

The solution is to easy. Add the following methods to the org.apache.commons.scxml2.model.State
class:

/**
     * set a user-defined property with the given {@code name}
     * 
     * @param name
     *            the name of the user-defined propery
     * @param value
     *            the value of the property
     */
    public final synchronized void setProperty(String name, String value)
    {
        if (this.extendProperties == null) {
            this.extendProperties = new HashMap<String, String>();
        }
        this.extendProperties.put(name, value);
    }

    /**
     * 
     * @param name
     *            the name of the user-defined propery
     * @return the value of the property with the given {@code name}
     */
    public final String getProperty(String name)
    {
        return extendProperties == null ? null : extendProperties.get(name);
    }

    /**
     * 
     * @return a set of user-defined properties names
     */
    public final Set<String> getPropertyNames()
    {
        return extendProperties == null ? null : extendProperties.keySet();
    }

    /**
     * 
     * @return the count of the user-defined properties
     */
    public final int getPropertyCount()
    {
        return extendProperties == null ? 0 : extendProperties.size();
    }

and extend the readState method of the SCXMLReader to read this properties from xml:

// reading user-defined properties
        int attrCount = reader.getAttributeCount();
        for (int i = 0; i < attrCount; i++) {
            QName attrName = reader.getAttributeName(i);
            String prefix = nullIfEmpty(attrName.getPrefix());
            String localPart = attrName.getLocalPart();
            if (prefix != null) {
                localPart = prefix + ":" + localPart;
            }
            if (ATTR_SRC.equals(localPart) || TTR_INITIAL.equals(localPart) || ATTR_ID.equals(localPart))
{
                continue;
            }
            state.setProperty(localPart, reader.getAttributeValue(i));
        }
