Method Detail

make

public static final org.millscript.commons.util.IList make(java.lang.Object obj)

Returns a list made from the specified object.

Parameters:

obj - the object to make a list from

Returns:

a List made from the specified object

sameAs

public static final boolean sameAs(java.lang.Object x,
                                   java.lang.Object y)

Checks if the two specified arguments are of the same type, but only for list compatible types.

Parameters:

x - first object to compare

y - second object to compare

Returns:

true if both objects are of the same type and list compatible, false otherwise

unmake

public static final java.lang.Object unmake(java.lang.Object obj,
                                            org.millscript.commons.util.IList<?> x)

Returns an object of the specified type, made from the specified list. This operation is essentially the reverse of the make method, above. e.g. if the target type is a String, the list is taken to be a list of characters making up a new string.

Parameters:

obj - the target object type

x - the list of constituent parts

Returns:

an object of the target type, made from the specified list
