Select DAT
Summary
The Select DAT allows you to fetch a DAT from any other location in the project, and to select any subset of rows and columns if it is a table.
Parameters - Select Page
Include First Row
firstrow - Forces the first row to be selected even if it is not specified by the Select Rows settings.
Include First Col
firstcol - Forces the first column to be selected even if it is not specified by the Select Cols settings.
Select Rows
extractrows - ⊞ - This parameter allows you to pick different ways of specifying the rows selected.
- All
all- All rows selected.
- by Name
byname- Rows selected using Start Row Name and End Row Name parameters.
- by Index
byindex- Rows selected using Start Row Index and End Row Index parameters.
- by Start Name, End Index
bynameindex- Rows selected using Start Row Name and End Row Index parameters.
- by Start Index, End Name
byindexname- Rows selected using Start Row Index and End Row Name parameters.
- by Values
bynames- Rows selected by specifying the row values explicitly.
- by Condition
byexpr- Rows selected by an expression to be evaluated for the from column.
Start Row Name
rownamestart - Specify the row name to start the selection range from.
Start Row Index
rowindexstart - Specify the row index to start the selection range from.
End Row Name
rownameend - Specify the row name to end the selection range.
End Row Index
rowindexend - Specify the row index to end the selection range.
Row Select Values
rownames - Specify actual row names that you want to select. You can use TouchDesigner's pattern matching (see wiki page Pattern Matching), for example row[1-4] will select all the rows names row1 thru row4. Some characters like ' need a \ in front of it.
Row Select Condition
rowexpr - Specify an expression that will be evaluated. If the expression evaluates to true, the row will be selected.
Expand the parameter and you will see that it is in expression mode.
By default, the Python expression is re.match('.*',me.inputCell.val) != None. '.*' means match any character multiple times, so this expression matches all values. If you want to match the parent's operator name followed by any numeric number you can use parent().name+'[0-9]*', where '[0-9]*' matches any numerical string. '.*'+parent().name+'.*' will match any cell that contains the operator's parent name. You can check Regular Expression Operations for additional information on how to use the Python Regular Expression module.
From Column
fromcol - When selecting rows by values, this parameter selects which column to use when matching cell values to Selected Row Values to determine which rows are selected.
Select Cols
extractcols - ⊞ - This parameter allows you to pick different ways of specifying the columns selected.
- All
all- All columns selected.
- by Name
byname- Columns selected using Start Col Name and End Col Name parameters.
- by Index
byindex- Columns selected using Start Col Index and End Col Index parameters.
- by Start Name, End Index
bynameindex- Columns selected using Start Col Name and End Col Index parameters.
- by Start Index, End Name
byindexname- Columns selected using Start Col Index and End Col Name parameters.
- by Values
bynames- Columns selected by specifying the column values explicitly.
- by Condition
byexpr- Rows selected by an expression to be evaluated for the from row.
Start Col Name
colnamestart - Specify the column name to start the selection range from.
Start Col Index
colindexstart - Specify the column index to start the selection range from.
End Col Name
colnameend - Specify the column name to end the selection range.
End Col Index
colindexend - Specify the column index to end the selection range.
Col Select Values
colnames - Specify actual column names that you want to select. You can use TouchDesigner's pattern matching (see wiki page Pattern Matching), for example colvalue[1-4] will select all the columns named colvalue1 thru colvalue4. Matching some characters like ' need a \ in front of it.
Col Select Condition
colexpr - Specify an expression that will be evaluated. If the expression evaluates to true, the column will be selected. See Row Select Condition for more details.
From Row
fromrow - When extracting columns by Specified Names, this parameter selects which row to use when matching cell values to Selected Col Values to determine which columns are selected.
Output
output - ⊞ - Determines what format will be used for output from the DAT.
- Input Data
data- Passes through data from first input without manipulation.
- Strings
string- Evaluates input data as strings, including expanding any variable values to full strings.
- Expressions
expr- Evaluates input data as expressions.
