- * An entity is the representation of program known objects in Firm.
- * The primary concept of entities is to represent members of complex
- * types, i.e., fields and methods of classes. As not all programming
- * language model all variables and methods as members of some class,
- * the concept of entities is extended to cover also local and global
- * variables, and arbitrary procedures.
+ * Licensees holding valid libFirm Professional Edition licenses may use
+ * this file in accordance with the libFirm Commercial License.
+ * Agreement provided with the Software.
*
- * An entity always specifies the type of the object it represents and
- * the type of the object it is a part of, the owner of the entity.
- * Originally this is the type of the class of which the entity is a
- * member.
- * The owner of local variables is the procedure they are defined in.
- * The owner of global variables and procedures visible in the whole
- * program is a universally defined class type "GlobalType". The owner
- * of procedures defined in the scope of an other procedure is the
- * enclosing procedure.
