-The new collection's content can be initialized by providing a @manifest_text@ or @splices@ key in the provided @collection@ object (see "splices":#splices below).
+The new collection's content can be initialized by providing a @manifest_text@ key in the provided @collection@ object, or by using the @replace_files@ option (see "replace_files":#replace_files below).
h3. delete
h3. get
-Gets a Collection's metadata by UUID or portable data hash. When making a request by portable data hash, attributes other than @portable_data_hash@ and @manifest_text@ are not returned, even when requested explicitly using the @select@ parameter.
+Gets a Collection's metadata by UUID or portable data hash. When making a request by portable data hash, attributes other than @portable_data_hash@, @manifest_text@, and @trash_at@ are not returned, even when requested explicitly using the @select@ parameter.
Arguments:
Note: Because adding access tokens to manifests can be computationally expensive, the @manifest_text@ field is not included in results by default. If you need it, pass a @select@ parameter that includes @manifest_text@.
+h4. Searching Collections for names of file or directories
+
+You can search collections for specific file or directory names (whole or part) using the following filter in a @list@ query.
+
+<pre>
+filters: [["file_names", "ilike", "%sample1234.fastq%"]]
+</pre>
+
+Note: @file_names@ is a hidden field used for indexing. It is not returned by any API call. On the client, you can programmatically enumerate all the files in a collection using @arv-ls@, the Python SDK @Collection@ class, Go SDK @FileSystem@ struct, the WebDAV API, or the S3-compatible API.
+
+As of this writing (Arvados 2.4), you can also search for directory paths, but _not_ complete file paths.
+
+In other words, this will work (when @dir3@ is a directory):
+
+<pre>
+filters: [["file_names", "ilike", "%dir1/dir2/dir3%"]]
+</pre>
+
+However, this will _not_ return the desired results (where @sample1234.fastq@ is a file):
+
+<pre>
+filters: [["file_names", "ilike", "%dir1/dir2/dir3/sample1234.fastq%"]]
+</pre>
+
+As a workaround, you can search for both the directory path and file name separately, and then filter on the client side.
+
+<pre>
+filters: [["file_names", "ilike", "%dir1/dir2/dir3%"], ["file_names", "ilike", "%sample1234.fastq%"]]
+</pre>
+
h3. update
Update attributes of an existing Collection.

+The collection's content can be updated by providing a @manifest_text@ key in the provided @collection@ object, or by using the @replace_files@ option (see "replace_files":#replace_files below).

-h2(#splices). Using "splices" to create/update collections
+h2(#replace_files). Using "replace_files" to create/update collections
-The @splices@ attribute can be used with the @create@ and @update@ APIs to efficiently copy individual files and directory trees from other collections, and copy/rename/delete items within an existing collection, without transferring any file data.
+The @replace_files@ option can be used with the @create@ and @update@ APIs to efficiently copy individual files and directory trees from other collections, and copy/rename/delete items within an existing collection, without transferring any file data.
-@splices@ keys indicate target paths in the new collection, and values specify sources that should be copied to the target paths.
+@replace_files@ keys indicate target paths in the new collection, and values specify sources that should be copied to the target paths.
* Each target path must be an absolute canonical path beginning with @/@. It must not contain @.@ or @..@ components, consecutive @/@ characters, or a trailing @/@ after the final component.
* Each source must be either an empty string (signifying that the target path is to be deleted), or @PDH/path@ where @PDH@ is the portable data hash of a collection on the cluster and @/path@ is a file or directory in that collection.
* In an @update@ request, sources may reference the current portable data hash of the collection being updated.
Example: delete @foo.txt@ from a collection
<notextile><pre>
-"collection": {
- "splices": {
- "/foo.txt": ""
- }
+"replace_files": {
+ "/foo.txt": ""
}
</pre></notextile>
Example: rename @foo.txt@ to @bar.txt@ in a collection with portable data hash @fa7aeb5140e2848d39b416daeef4ffc5+45@
<notextile><pre>
-"collection": {
- "splices": {

Example: delete current contents, then add content from multiple collections
<notextile><pre>
-"collection": {
- "splices": {
- "/": "",
- "/copy of collection 1": "1f4b0bc7583c2a7f9102c395f4ffc5e3+45/",

+ "/copy of collection 2": "ea10d51bcf88862dbcc36eb292017dfd+45/"
}
</pre></notextile>
Example: replace entire collection with a copy of a subdirectory from another collection
<notextile><pre>
-"collection": {
- "splices": {
- "/": "1f4b0bc7583c2a7f9102c395f4ffc5e3+45/subdir"

</pre></notextile>
A target path with a non-empty source cannot be the ancestor of another target path in the same request. For example, the following request is invalid:
<notextile><pre>
-"collection": {
- "splices": {
- "/foo": "fa7aeb5140e2848d39b416daeef4ffc5+45/",
- "/foo/this_will_return_an_error": ""
- }
+"replace_files": {
+ "/foo": "fa7aeb5140e2848d39b416daeef4ffc5+45/",
+ "/foo/this_will_return_an_error": ""
}
</pre></notextile>
