public class MapAssignStmt

extends AssignStmt

The MapAssignStmt class represents a statement that is an assignment to an element of a map.

Field Summary

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

Constructor Summary

MapAssignStmt(java.lang.String m, Expr i, Expr e)
The constructor for the MapAssignStmt class initializes the public final fields in this class that refer to the elements of the assignment.

MapAssignStmt(Token m, Expr i, 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, 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

mapname

public final Token mapname

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

index

public final Expr index

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

Constructor Detail

MapAssignStmt

public MapAssignStmt(Token m,
                     Expr i,
                     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 expr into the map

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

MapAssignStmt

public MapAssignStmt(java.lang.String m,
                     Expr i,
                     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 expr into the map

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
