Constructor Detail

AlignofExpression

public AlignofExpression(Expression expr)

Constructs a new alignof expression with the specified expression.

Parameters:

expr - the operand expression.

Throws:

NotAnOrphanException - if expr has a parent object.

AlignofExpression

public AlignofExpression(java.util.List pspecs)

Constructs a new alignof expression with the given specifiers.

Parameters:

pspecs - the operand specifiers.

Method Detail

defaultPrint

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

Prints an alignof 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 operand expression.

Specified by:

getExpression in interface Intrinsic

Returns:

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

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)

Checks if the alignof expression is equal to the specified object.

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
