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.

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

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
