Class UriPattern

  • public final class UriPattern
extends SmithyPattern
    Represents a URI pattern.

    A URI pattern is an absolute path segment used to route to operations. The pattern must start with "/", must not contain empty segments (i.e., "//"), must not contain a fragment (i.e., "#"), and must not end with "?".

    Labels may appear in the pattern in the form of "{label}". Labels must not be repeated, must make up an entire path segment (e.g., "/{foo}/baz"), and the label name must match the regex "^[a-zA-Z0-9_]+$". No labels can appear after the query string.

    Greedy labels, a specialized type of label, may be specified using "{label+}". Only a single greedy label may appear in a pattern, and it must be the last label in a pattern.
