Method Detail

isLiteral

public static boolean isLiteral(java.lang.Object o)

Is the object a literal value? This is only an approximation. Note that not all of these are implemented with immutable classes. Best practice is to treat them as immutable.

list

public static java.util.List list(java.lang.Object... item)

Make a list from the arguments

Parameters:

item - 0 or more Objects

Returns:

unmodifiable List

get

public static java.lang.Object get(java.util.List list,
                                   int i)

Get the i-th element of a List (0 based)

Parameters:

list - the list to get an element from

i - 0 based position, if negative, count from end of list

Returns:

element

append

public static java.util.List append(java.util.List list,
                                    java.lang.Object... item)

Append items to a list

Parameters:

list - the list to append to

item - 0 or more Objects

Returns:

unmodifiable List

concatenate

public static java.util.List concatenate(java.util.List... list)

Concatenate lists

Parameters:

list - the lists to concatenate

Returns:

unmodifiable List

insertBefore

public static java.util.List insertBefore(java.util.List list,
                                          int pos,
                                          java.lang.Object item)

Insert item before pos-th item in list. Index starts at 0. pos may be negative, meaning count from end of list.

Parameters:

list -

pos -

item -

Returns:

unmodifiable List

remove

public static java.util.List remove(java.util.List list,
                                    int pos)

Remove pos-th item from list. pos may be negative, meaning count from end of list.

Parameters:

list -

pos -

Returns:

unmodifiable List

reverse

public static java.util.List reverse(java.util.List list)

Reverse the list

Parameters:

list -

Returns:

unmodifiable List
