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));
}
