Constructor Detail

VaArgExpression

public VaArgExpression(Expression expr,
               java.util.List pspecs)

Constructs a va_arg expression with the specified expression and specs.

Parameters:

expr - the operand expression.

pspecs - the list of specifiers.

Throws:

NotAnOrphanException - if expr has a parent.

Method Detail

defaultPrint

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

Prints a __builtin_va_arg 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.

Specified by:

getExpression in interface Intrinsic

Returns:

the expression or null if this sizeof operator is being applied to a type.

getSpecifiers

public java.util.List getSpecifiers()

Returns the type argument which is also the type of return value.

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 va_arg 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
