Examples of org.apache.sling.api.request.RequestPathInfo

org.apache.sling.api.request.RequestPathInfo

Sling breaks the request URI into four parts: the path itself, optional dot-separated selectors and extension that follow it, and an optional path suffix.

Decomposition of a Request URL

{@link #getResourcePath() content path} - The longest substring of the requestURI resolving to a {@link org.apache.sling.api.resource.Resource} object suchthat the content path is either the complete request URI or the next character in the request URI after the content path is either a dot (.) or a slash (/).
{@link #getSelectors() selectors} - If the first character in therequest URI after the content path is a dot, the string after the dot upto but not including the last dot before the next slash character or the end of the request URI. If the content path spans the complete request URI or if a slash follows the content path in the request, then no seletors exist. If only one dot follows the content path before the end of the request URI or the next slash, no selectors exist. The selectors are available as {@link #getSelectorString() a single string} and as an{@link #getSelectors() array of strings}, which is the selector string splitted on dots.
{@link #getExtension() extension} - The string after the last dot afterthe content path in the request uri but before the end of the request uri or the next slash after the content path in the request uri. If the content path spans the complete request URI or a slash follows the content path in the request URI, the extension is empty.
{@link #getSuffix() suffix path} - If the request URI contains a slashcharacter after the content path and optional selectors and extension, the path starting with the slash upto the end of the request URI is the suffix path.

Examples:

URI	Content Path	Selectors	Extension	Suffix
/a/b	/a/b	null	null	null
/a/b.html	/a/b	null	html	null
/a/b.s1.html	/a/b	s1	html	null
