Parameters:

pspecs - the list of specifiers.

expr - the operand expression.

Throws:

java.lang.IllegalArgumentException - if expr is invalid.

NotAnOrphanException - if expr has a parent.

Method Detail

defaultPrint

public static void defaultPrint(OffsetofExpression e,
                java.io.PrintWriter o)

Prints a __builtin_offsetof expression to a stream.

Parameters:

e - The expression to print.

o - The writer on which to print the expression.

toString

public java.lang.String toString()

Description copied from class: Expression

Returns a string representation of the expression

Overrides:

toString in class Expression

getExpression

public Expression getExpression()

Returns the expression operand.

Specified by:

getExpression in interface Intrinsic

Returns:

the expression that is the second parameter to this function (member-designator)

getSpecifiers

public java.util.List getSpecifiers()

Returns the list of specifiers.

setClassPrintMethod

public static void setClassPrintMethod(java.lang.reflect.Method m)

Overrides the class print method, so that all subsequently created objects will use the supplied method.

Parameters:

m - The new print method.

equals

public boolean equals(java.lang.Object o)

Compares the expression with the specified object for equality.

Overrides:

equals in class Expression

Parameters:

o - the object to be compared with.

Returns:

true if o!=null, this.getClass()==o.getClass(), and this.children.equals(o.children) || this.children==o.children==null
