Hello Ant Developers, I believe the API regarding properties is incomplete (at least from a performance point of view).
A bit of background information: I make use of the new property API (1.8.1) which allows me to evaluate ${..} in a different way. In my case, the body ${..} will be a Java Unified Expression (EL), see [1]. Now, EL comes with it's own object storgage and with the help of additional tasks, a user can create "EL properties". Assume this task would be "<elproperty /> similar to Ant's property task. Then there could be something like <elproperty name="p" value=".." /> <property name="p" value=".." /> At this point there is a property named "p" in EL's storage and a property named "p" in Ant's default storage. Then, assume that there is this <echo /> task and that "handling of EL" has been enabled. <echo> ${p} ${property.p} </echo> The first embedded ${p} resolves to the object in EL's storage, cause PropertyEvaluators are added in LIFO order. In my case, that is exactly what I want (in general, I believe it is better to let the user determine the order). However, I also want to give my users the chance to explicitly reference the object in Ant's storage, i.e. the Ant "string" property. That's what the second embedded reference, ${property.p} is all about. My question is how to access to Ant property 'p' in a given project? Obviously (?) I can't make use of Project.getUserProperty(String propertyName) cause this would invoke my own EL property evaluator. All I found is Project p = ... String name = 'p'; p.getProperties().get(name); However, a closer look to getProperties() reveals that this method is essentially implemented as public Hashtable getProperties() { //avoid concurrent modification: synchronized (properties) { return new Hashtable(properties); } // There is a better way to save the context. This shouldn't // delegate to next, it's for backward compatibility only. } ======================================================== So my question is essentially how to retrieve an Ant property in Ant's storage? ======================================================== Greetz, Wolfgang.
