public class PointerBinaryExpr

extends BinaryExpr

implements TokenId

Pointer binary expression.

The left operand is a pointer value. The right operand is an integer offset. The parser maintains this order. If the right operand is a pointer, then the parser implicitly exchanges the operands.

PointerBinaryExpr

public PointerBinaryExpr(Expr expr1,
                         int op,
                         Expr expr2)

Constructs a pointer binary expression.

Parameters:

expr1 - a pointer expression

op - + or -

expr2 - an integer expression

Method Detail

accept

public void accept(Visitor v)

Description copied from class: ASTree

Is a method for the visitor pattern. It calls atXXX() on the given visitor, where XXX is the class name of the node object.

Specified by:

accept in class ASTree

getType

public byte[] getType()

Returns the type of the resulting value of the binary expression.

Specified by:

getType in interface Expr

Returns:

the encoded type.

getPointer

public Expr getPointer()

Returns the left operand.

getOffset

public Expr getOffset()

Returns the right operand.

operatorId

public int operatorId()

Description copied from class: OperatorExpr

Returns the token identifier of the operator name. See ast.TokenId

Specified by:

operatorId in class OperatorExpr

operatorName

public java.lang.String operatorName()

Description copied from class: OperatorExpr

Returns the string representation of the operator name.

Specified by:

operatorName in class OperatorExpr
