Interface TypeList

All Known Implementing Classes:

RegisterSpecList, StdTypeList

public interface TypeList

List of Type instances (or of things that contain types).

Method Summary

Modifier and Type	Method and Description
Type	getType(int n) Gets the indicated element.
int	getWordCount() Gets the number of 32-bit words required to hold instances of all the elements of this list.
boolean	isMutable() Returns whether this instance is mutable.
int	size() Gets the size of this list.
TypeList	withAddedType(Type type) Returns a new instance which is identical to this one, except that the given item is appended to the end and it is guaranteed to be immutable.

Method Detail

isMutable

boolean isMutable()

Returns whether this instance is mutable. Note that the TypeList interface itself doesn't provide any means of mutation, but that doesn't mean that there isn't an extra-interface way of mutating an instance.

Returns:

true if this instance is mutable or false if it is immutable

size

int size()

Gets the size of this list.

Returns:

>= 0; the size

getType

Type getType(int n)

Gets the indicated element. It is an error to call this with the index for an element which was never set; if you do that, this will throw NullPointerException.

Parameters:

n - >= 0, < size(); which element

Returns:

non-null; the indicated element

getWordCount

int getWordCount()

Gets the number of 32-bit words required to hold instances of all the elements of this list. This is a sum of the widths (categories) of all the elements.

Returns:

>= 0; the required number of words

withAddedType

TypeList withAddedType(Type type)

Returns a new instance which is identical to this one, except that the given item is appended to the end and it is guaranteed to be immutable.

Parameters:

type - non-null; item to append

Returns:

non-null; an appropriately-constructed instance
