 +=== packageT(#​id,​ '​fullname'​) ​ ===
 +
 +Represents the package declaration.
 +
 +=== Arguments ===
 +== ==
 +**#id**: id\\ 
 +the unique ID assigned to this fact. 
 +
 +**'​fullname'​**:​ atom\\ ​
 +package name of this package declaration,​ as an atom. 
 +
 +**E. g.:**\\ ''​packageT(42,​ '​org.cs3.pl.astvisitor'​).''​\\ ​
 +''​packageT(defaultPackage,​ ' '​).'' ​  (for the default Java package) <- **++  Changed in JT 2.6.3 | Previously the PEF for the default package was ''​packageT(null,'​ '​)''​ ++**
 +
 +**Note:** packageT does not have the ID of the children in his declaration. packageT has so called unreferenced_children,​ that means the children referencing the parent, but not the other way around.\\
 +The unreferenced_children from packageT are [[compilationunitt|compilationUnitT]],​ see also [[..:​..:​prologast#​basic_structure|Program Element Facts for Java AST]]
 +
 +
 +=== Sample Java Source ===
 +== ==
 +<Code lang-java>​
 + ​package packaged.de.tests;​
