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 value pointed by the operand expression.

Specified by:
getType in interface Expr
Returns:
the encoded type.

isLvalue

public boolean isLvalue()
Description copied from interface: LvalueExpr
Returns true if the expression is really an l-value.

Specified by:
isLvalue in interface LvalueExpr

hasAddress

public boolean hasAddress()
Description copied from interface: LvalueExpr
Returns true if the expression can be an operand of '&'.

Specified by:
hasAddress in interface LvalueExpr

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

getTag

protected java.lang.String getTag()
Description copied from class: ASTree
Returns the type of this node. This method is used by toString().

Overrides:
getTag in class OperatorExpr
