public class MapBitAssignStmt

extends AssignStmt

The MapBitAssignStmt represents an assignment to a single bit within an element within a map.

Field Summary

Expr	bit The bit field stores a reference to the expression which is evaluated to yield the bit index into the element of the map.
Expr	index The index field stores a references to the expression which is evaluated to yield the index into the map.
Token	mapname The mapname field stores a reference to the name of the map whose element is being assigned to.

Constructor Summary

MapBitAssignStmt(Token m, Expr i, Expr b, Expr e)
The constructor for the MapAssignStmt class initializes the public final fields in this class that refer to the elements of the 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

mapname

public final Token mapname

The mapname field stores a reference to the name of the map whose element is being assigned to.

index

public final Expr index

The index field stores a references to the expression which is evaluated to yield the index into the map.

bit

public final Expr bit

The bit field stores a reference to the expression which is evaluated to yield the bit index into the element of the map.

Constructor Detail

MapBitAssignStmt

public MapBitAssignStmt(Token m,
                        Expr i,
                        Expr b,
                        Expr e)

The constructor for the MapAssignStmt class initializes the public final fields in this class that refer to the elements of the assignment.

Parameters:

m - the string name of the map as a token

i - the expression representing the index into the map

b - the expression representing the bit index into the element

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)

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
