public class VarBitAssignStmt

extends AssignStmt

The VarBitAssignStmt class represents an assignment to a single bit within a local or global variable.

Field Summary

Expr	bit The bit field stores a reference to the expression that represents the index of the bit to assign to.
Token	variable The variable field stores a reference to the token that represents the name of the variable being assigned to.

Constructor Summary

VarBitAssignStmt(Token m, Expr b, 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) 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

variable

public final Token variable

The variable field stores a reference to the token that represents the name of the variable being assigned to.

bit

public final Expr bit

The bit field stores a reference to the expression that represents the index of the bit to assign to.

Constructor Detail

VarBitAssignStmt

public VarBitAssignStmt(Token m,
                        Expr b,
                        Expr e)

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

Parameters:

m - the string name of the variable as a token

b - an expression representing the index of the bit

e - an 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)

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
