  avrora.core.isdl.ast.Stmt
      avrora.core.isdl.ast.CallStmt

public class CallStmt

extends Stmt

The CallStmt class represents a call to a subroutine that does not produce a value.

Field Summary

java.util.List	args The args fields stores a reference to a list of expressions that are evaluated and passed as arguments to the subroutine.
Token	method The method field stores a string that represents the name of the subroutine being called.

Constructor Summary

CallStmt(java.lang.String m, java.util.List a)
The constructor of the CallStmt class simply initializes the references to the subroutine name and arguments.

CallStmt(Token m, java.util.List a)
The constructor of the CallStmt class simply initializes the references to the subroutine name and arguments.

Method Summary

Stmt	accept(StmtRebuilder r, java.lang.Object env) The accept() method implements one half of the visitor pattern for visiting the abstract syntax trees representing the code of a particular instruction or subroutine.
void	accept(StmtVisitor v) The accept() method implements one half of the visitor pattern for visiting the abstract syntax trees representing the code of a particular instruction or subroutine.
java.lang.String	toString() The toString() method recursively converts this statement to a string.

Field Detail

method

public final Token method

The method field stores a string that represents the name of the subroutine being called.

args

public final java.util.List args

The args fields stores a reference to a list of expressions that are evaluated and passed as arguments to the subroutine.

Constructor Detail

CallStmt

public CallStmt(Token m,
                java.util.List a)

The constructor of the CallStmt class simply initializes the references to the subroutine name and arguments.

Parameters:

m - the name of the subroutine as a string

a - list of expressions representing the arguments to the subroutine

CallStmt

public CallStmt(java.lang.String m,
                java.util.List a)

The constructor of the CallStmt class simply initializes the references to the subroutine name and arguments.

Parameters:

m - the name of the subroutine as a string

a - list of expressions representing the arguments to the subroutine

Method Detail

accept

public void accept(StmtVisitor v)

The accept() method implements one half of the visitor pattern for visiting the abstract syntax trees representing the code of a particular instruction or subroutine.

Specified by:

accept in class Stmt

Parameters:

v - the visitor to accept

toString

public java.lang.String toString()

The toString() method recursively converts this statement to a string.

Returns:

a string representation of this statement

accept

public Stmt accept(StmtRebuilder r,
                   java.lang.Object env)

The accept() method implements one half of the visitor pattern for visiting the abstract syntax trees representing the code of a particular instruction or subroutine. The StmtRebuilder interface allows visitors to rearrange and rebuild the statements.

Specified by:

accept in class Stmt

Parameters:

r - the visitor to accept

Returns:

the result of calling the appropriate visit() of the rebuilder passed
