This node generates a work item for each incoming work item that takes all file results tagged file
and compiles them into a compressed archive. The output
result of each work item is the archive file.
TOP Attributes

File path to the output archive file. |
|
string |
Array of path strings representing the source files compiled into the archive. |
Parameters
Node
Mode
How do decide what file(s) to compress:
Custom File Path
Set the path to the file to compress in the File Path parameter.
Upstream Output Files
Compress any file paths in the output
attributes of incoming work items if they have the given file tag.
File To Compress
When Mode is “Custom File Path”, the path of the file to be compressed.
File Tag
When Mode is “Upstream Output Files”, compress paths in the output
attributes of incoming work items if they have this file tag.
Compression Method
The archive method/format, ZIP or tar.gz
.
Output File
Specify the file path of the generated archive file. The file extension will be added if not specified.
Compress Archive
When Compression Method is set to ZIP, this parameter determines whether or not the .zip archive is compressed.
Append to Existing Archive
When Compression Method is set to ZIP, this parameter determines if files should be appended to an existing .zip archive if the Output File already exists on disk. If appending is disabled, existing .zip archives are overwritten.
Compression Level
When Compression Method is set to TAR GZ, this parameter determines how compressed the archive should be. A larger value will take longer to compress, but results in a smaller file size. The value can range between 1 and 9.
Schedulers
TOP Scheduler Override
This parameter overrides the TOP scheduler for this node.
Work Item Label
Determines how the node should label its work items. This parameter allows you to assign non-unique label strings to your work items which are then used to identify the work items in the attribute panel, task bar, and scheduler job names.
No Label
The work items on this node do not have a label.
Inherit From Upstream Item
The work items inherit their labels from their parent work items.
Custom Expression
The work item label is set to the Label Expression custom expression which is evaluated for each item.
Node Defines Label
The work item label is defined in the node’s internal logic.
Label Expression
When on, this parameter specifies a custom label for work items created by this node. The parameter can be an expression that includes references to work item attributes or built-in properties. For example, $OS: @pdg_frame
will set the label of each work item based on its frame value.
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.
