Converts – if possible – a given DomainValue to a Java object that is
appropriately initialized.
Converts – if possible – a given DomainValue to a Java object that is
appropriately initialized.
Every domain that supports the creation of a Java object's based on a domain value is expected to implement this method and to test if it can create a precise representation of the given value. If not, the implementation has to delegate the responsibility to the super method to creat an abstract representation.
abstract override def toJavaObject(value : DomainValue): Option[Object] = { if(value...) // create and return Java object else super.toJavaObject(value) }
Some(Object) is returned if it was possible to create a compatible
corresponding Java object; otherwise None is returned.
Default: None unless the value is null. In the latter case Some(null)
is returned.
This operation is generally only possible if the domain value maintains enough state information to completely initialize the Java object.
Mixed in by domains that support the conversation of a
DomainValueinto a respective Java object. This Java object can then be used to perform method invocations.Limitation
Using
AsJavaObjectwill only work reasonably iff the respective class is either in the classpath of the JVM or a class loader (initialized with the project's classpath) is used. The latter, however, does not work for classes on the bootclasspath (e.g.,java.lang.String). In that case it is necessary to check that the code of the analyzed application is compatible with the one on the class path. To avoid accidental imprecision in the analysis you should use this features only for stable classes belonging to the core JDK (java.lang....)
