File Decompress TOP node

Decompresses archive files specified by incoming work items into individual files.

On this page	Top_attributes Parameters Node Schedulers Examples
Since	17.5

This node looks in the output attribute on each incoming work items for file paths tagged file/archive. If the file name’s extension is supported (.zip or .tar.gz), the node extracts the files inside the archive into a given directory.

(Nodes that produce file results (for example, File Pattern or File Compress) should automatically tag archive files as file/archive based on the extension.)

If you just want to extract files from one or more pre-existing archive files, do the following:

Create a File Pattern node.
- Set the Pattern to match the archive(s) you want to extract. For example, $PDG_DIR/sources/*.zip.
- Make sure Split results into separate items is on.
The node will generate work items for each archive, with its output attribute set to the archive path. The path should automatically be tagged file/archive based on the extension.
Connect a File Decompress node. Turn on Output file and set it to the directory you want to extract files into.

Warning

The File Decompress node sets each work item’s output to the path of the directory it extracted into, not to the list of extracted files, as you might expect.

TOP Attributes

`input_archives`	string	A list of input archives that will be decompressed.
`output_dirs`	string	A list of directories where archives will be extracted into.

Parameters

Node

Output Folder

Turn this on and set it to the path to the directory you want to extract files into. The node will create the directory if it does not exist.

Schedulers

TOP Scheduler Override

This parameter overrides the TOP scheduler for this node.

Work Item Priority

This parameter determines how the current scheduler prioritizes the work items in this node.

Inherit From Upstream Item

The work items inherit their priority from their parent items. If a work item has no parent, its priority is set to 0.

Custom Expression

The work item priority is set to the value of Priority Expression.

Node Defines Priority

The work item priority is set based on the node’s own internal priority calculations.

This option is only available on the Python Processor TOP, ROP Fetch TOP, and ROP Output TOP nodes. These nodes define their own prioritization schemes that are implemented in their node logic.

Priority Expression

This parameter specifies an expression for work item priority. The expression is evaluated for each work item in the node.

This parameter is only available when Work Item Priority is set to Custom Expression.
