Prev	4.4. Model Manipulation Rules	Next

	Description
	This rule copies a subtree of the current model space to another location.

	Syntax
CopyRuleAST ::= copy ( CopyContentsAST ) ; CopyContentsAST ::= ArithmeticTermAST , ArithmeticTermAST , VariableRefAST , CopySemanticsAST CopySemanticsAST ::= copy_boundary_edges \| skip_boundary_edges The first parameter (source entity) is the root of the sub-model to be copied, and the second parameter is the target container. Both source entity and target container is an ASM term that evaluates to a model element constant referencing an entity.

Syntax

CopyRuleAST ::= copy ( CopyContentsAST ) ;

CopyContentsAST ::= ArithmeticTermAST , ArithmeticTermAST , VariableRefAST , CopySemanticsAST								

CopySemanticsAST ::= copy_boundary_edges | skip_boundary_edges

The first parameter (source entity) is the root of the sub-model to be copied, and the second parameter is the target container.

Both source entity and target container is an ASM term that evaluates to a model element constant referencing an entity.

Semantics

	Semantics
A reference to the root element of the newly created sub-model is stored in a variable. The copy semantics defines whether to copy (`copy_boundary_edges`) or not to copy the edges (`skip_boundary_edges`) that are going to or coming from outside the sub-model under copy.

A reference to the root element of the newly created sub-model is stored in a variable.

The copy semantics defines whether to copy (copy_boundary_edges) or not to copy the edges (skip_boundary_edges) that are going to or coming from outside the sub-model under copy.

Remark. Note that the terminology has changed compared to previous Viatra versions (copy_boundary_edges instead of keep_edges; skip_boundary_edges instead of drop_edges).
