Constructor Summary

VarAssignStmt(java.lang.String n, Expr e)
The constructor for the VarAssignStmt class simply initializes the internal references to the internal members of this assignment.

VarAssignStmt(Token n, Expr e)
The constructor for the VarAssignStmt class simply initializes the internal references to the internal members of this assignment.

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.

Constructor Detail

VarAssignStmt

public VarAssignStmt(Token n,
                     Expr e)

The constructor for the VarAssignStmt class simply initializes the internal references to the internal members of this assignment.

Parameters:

n - the string name of the variable as a token

e - the expression representing the right hand side of the assignment

VarAssignStmt

public VarAssignStmt(java.lang.String n,
                     Expr e)

The constructor for the VarAssignStmt class simply initializes the internal references to the internal members of this assignment.

Parameters:

n - the string name of the variable as a token

e - the expression representing the right hand side of the assignment

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
