OP Find DAT
The OP Find DAT traverses the component hierarchy starting at one component and looking at all nodes within that component, and outputs a table with one row per node that matches criteria the user chooses. For example, the criteria could be all Ramp TOPs, or all nodes whose name starts with “
wave”, or all nodes with the Clone parameter set to “
master1”, or all Geometry components with a tag called “
The criteria can limited to include only nodes of certain families, or certain operator types. It can filter on matching its path, certain parameters containing certain values (both constant and expressions), comments, tags, or the content of a DAT containing certain strings.
You can also cause the DAT to only look to some depth of the hierarchy from the specified component, such as 2 levels down, or limitless.
Criteria can be case-sensitive or not, but case-sensitive On or Off applies to all criteria in the OP Find DAT.
Furthermore you can exclude some nodes using more specialized criteria by returning a True of False in a callback contained in the attached callback DAT.
With the Combine Filters Menu (Any or All, Default is All), you can do an "or" or "and" on the pattern matching criterea.
It also takes an optional DAT containing a list of operators (eg, another OP Find DAT) which can be used to chain filters.
There is a variety of columns that you can select from including
id is a member of the operator, which is an integer unique to the node, and doesn't change during the running of the TouchDesigner process.)
You can also output custom columns by defining the column names in the callback DAT, and filling in the column cells via another function in the callback DAT. For example, you can output a custom column which is the
tx parameter value of the node.
You can control when the OP Find DAT cooks. Normally it cooks whenever any of the nodes in the specified hierarchy changes. Using the Active Cook menu parameter, you can also force-cook it every frame, or turn off cooking entirely. You can also click the Pulse parameter on Active Cook in order to force-cook it once, or do the equivalent using the node.cookpulse.pulse() python call.
Instead of being give the path to a component to start at, the OP Find DAT can take an input DAT containing a pre-generated list of paths to nodes to start from, and merge the results of each input line together in the output. To use this, the input DAT should contain the node “id” as the first column, which can be generated with another OP Find DAT with the Column called “ID” turned on.
For example, say you first list all components that are panels, then you separate into groups based on type or Clone parameter. The first OP Find DAT pre-filters a huge hierarchy to a small fraction of the nodes, the subsequent OP Find DATs are operating on simpler sets to eliminate a lot of checking and cooking.

customcombine - Specify which filters to combine in the search.
namefilter - Use the operator's names like 'wave1', 'wave2', etc.

Parent Path parameter on this DAT's
Exclude Path (relative)
excludefilter - Specify a relative path that should be excluded from the search.
commentfilter - Only match operators that include the here specified comment string.
