WaitForFiles¶
Wait for file(s) matching a certain criteria to exist in filesystem before continuing operation.
Passes data through if files are found, None otherwise. Also passes the files found status (true/false) through a port which can then be wired into the update port of a node further down the pipeline (triggering its execution, for example). The matching criteria uses the same format as PathIterator (see that node's docs.) Version 1.1.0
Ports/Properties¶
files_found¶
True if all required files have been found, False otherwise. Can be wired into another node to trigger its execution.
path_to_check¶
Path to check. Accepts the same format as PathIterator node.
num_required_files¶
In case where the path_to_check uses wildcards, this is the minimum number of files matching the path which need to be present before operation will continue.
wait_for_files_timeout¶
Wait for the input file(s) to appear for up to this many seconds before timing out. A value of 0 means the pipeline will not wait for the file (essentially skipping this node).
check_interval¶
How often to check for the expected files.
cloud_host¶
Cloud storage host to use (if any). You can override this option to select from what kind of cloud storage service data should be downloaded. On some environments (e.g., on NeuroScale), the value Default will be map to the default storage provider on that environment.
cloud_account¶
Cloud account name on storage provider (use default if omitted). You can override this to choose a non-default account name for some storage provider (e.g., Azure or S3.). On some environments (e.g., on NeuroScale), this value will be default-initialized to your account.
cloud_bucket¶
Cloud bucket to read from (use default if omitted). This is the bucket or container on the cloud storage provider that the file would be written to. On some environments (e.g., on NeuroScale), this value will be default-initialized to a bucket that has been created for you.
cloud_credentials¶
Secure credential to access cloud data (use default if omitted). These are the security credentials (e.g., password or access token) for the the cloud storage provider. On some environments (e.g., on NeuroScale), this value will be default-initialized to the right credentials for you.
set_breakpoint¶
Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.
metadata¶
User-definable meta-data associated with the node. Usually reserved for technical purposes.
