The child nodes of this node.

The hash value of the value, which allows the value to be an element of a hash-based set or key of a hash-based map. Implementations must respect the constraint that:

• if x==y then x.hash==y.hash.

Therefore, a class which refines equals must also refine hash.

In general, hash values vary between platforms and between executions of the same program.

Note that when executing on a Java Virtual Machine, the 64-bit Integer value returned by an implementation of hash is truncated to a 32-bit integer value by taking the exclusive disjunction of the 32 lowest-order bits with the 32 highest-order bits, before returning the value to the caller.

The name of the identifier.

The prefix for this kind of identifier – \i for a lowercase identifier, \I for an uppercase identifier.

The text of the identifier, that is its name and, if used, the prefix.

If true, use the \i/\I prefix.

This property is only of concern to tools which deal immediately with source code; it does not influence the equality of Identifier instances.

(If this is false and the name requires a prefix, an AssertionError is thrown.)

Whether this identifier is a valid Ceylon identifier. The LIdentifier.internal() and UIdentifier.internal() constructors allow compilers and other tools to create identifiers that contain dollar signs; these identifiers will never collide with regular Ceylon identifiers, because they are not valid in Ceylon.

Creates a copy of this identifier. All parameters default to the value of the corresponding parameter of this instance.
