Description copied from class: Expression

Returns a string representation of the expression

Overrides:

toString in class Expression

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.

getSpecifiers

public java.util.List getSpecifiers()

Returns the list of specifiers of the typecast.

getExpression
