< To: ATL

The ATL standard library consists of the types built into ATL and of their operations. It is based on the OCL 2.0 standard library as described in chapter 11 of the UML 2.0 OCL Final Adopted specification. However, some extensions have been made (see ATL_FAQ#How_close_is_ATL_navigation_language_from_the_OCL_2.0_standard.3F).

In EMFVM, the ATL standard library is mostly implemented in the ExecEnv Java class. For each type T, a CVS link is given to the Java class implementing T in the Regular ATL virtual machine. In each class, operations available from the ATL language (as opposed to implementation-specific methods) are represented as Java methods located below the following comment:

 // Native Operations Below

In some of these classes, there are two additional comments delimiting:

  • Operations specified by OCL 2.0:
 // OCL Operations
  • Operations added in ATL:
 // Additional Operations

All of these Java classes are located in the org.atl.engine.vm.nativelib package.

When the description given here is not complete enough, it is possible to go and read the Java implementation. This way, it is possible to know, for instance: the list of available operations and their semantics (e.g. operation String.regexReplaceAll(a : String, b : String) is implemented in ASMString using java.lang.String.replaceAll(String a, String b)).

Primitive Types

Boolean

The Boolean OCL type is implemented by the ASMBoolean (deprecated version) Java class. The underlying Java type is boolean.

Integer

The Integer OCL type is implemented by the ASMInteger (deprecated version) Java class. The underlying Java type is int.

Real

The Real OCL type is implemented by the ASMReal (deprecated version) Java class. The underlying Java type is double.

String

The String OCL type is implemented by the ASMString (deprecated version) Java class. The underlying Java type is java.lang.String.

Collection Types

Collection

The Collection OCL type is implemented by the ASMCollection (deprecated version) Java class. There is no underlying Java type for this abstract type. However, all concrete collection types are implemented by sub-classes of java.util.Collection.

Bag

The Bag OCL type is implemented by the ASMBag (deprecated version) Java class. The underlying Java type is java.util.ArrayList.

OrderedSet

The OrderedSet OCL type is implemented by the ASMOrderedSet (deprecated version) Java class. The underlying Java type is java.util.LinkedHashSet.

Sequence

The Sequence OCL type is implemented by the ASMSequence (deprecated version) Java class. The underlying Java type is java.util.ArrayList.

Set

The Set OCL type is implemented by the ASMSet (deprecated version) Java class. The underlying Java type is java.util.HashSet.

Additional Types

The types described in this section are not part of the OCL 2.0 specification.

Map

The Map OCL type is implemented by the ASMMap (deprecated version) Java class. The underlying Java type is java.util.HashMap.
