public class VarBitRangeAssignStmt

extends AssignStmt

The VarBitRangeAssignStmt method represents an assignment to a range of bits within a local or global variable.

Field Summary

int	high_bit The high_bit field stores the highest bit of the range of bits being assigned.
int	low_bit The low_bit field stores the lowest bit of the range of bits being assigned.
Token	variable The variable field stores a reference to the token that represents the name of the variable being assigned to.

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.

                             Token h,
                             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

l - the low bit of the range of bits being assigned

h - the high bit of the range of bits being assigned

e - an expression that represents 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
