Constructor Detail

ConditionalExpr

                       Expr elseExpr)

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()

Description copied from interface: Expr

Returns the type of the resulting value of evaluating the expression. See ast.TypeId

Specified by:

getType in interface Expr

Returns:

the encoded type.

getCondition

public Expr getCondition()

Returns the condition part.

getThen

public Expr getThen()

Returns the then part.

getElse

public Expr getElse()

Returns the else part.

isLvalue

public boolean isLvalue()

Returns false. ANSI C does not allow a conditional expresion as 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
