CommandLineBinding-class: CommandLineBinding Class
In tengfei/cwl.R: R objects for common work flow language representation

Description Details Fields Examples

When listed under inputBinding in the input schema, the term "value" refers to the the corresponding value in the input object. For binding objects listed in CommandLineTool.arguments, the term "value" refers to the effective value after evaluating valueFrom.

The binding behavior when building the command line depends on the data type of the value. If there is a mismatch between the type described by the input schema and the effective value, such as resulting from an expression evaluation, an implementation must use the data type of the effective value.

characterAdd prefix and the string to the command line.
numericAdd prefix and decimal representation to command line.
logicalIf true, add prefix to the command line. If false, add nothing.
FileAdd prefix and the value of File.path to the command line.
*ArrayIf itemSeparator is specified, add prefix and the join the array into a single string with itemSeparator separating the items. Otherwise add prefix and recursively add individual elements.
*objectAdd prefix only, and recursively add object fields for which inputBinding is specified.
nullAdd nothing.

position: [integer] The sorting key. Default position is 0.
prefix: [character] Command line prefix to add before the value.
separate: [logical] If true (default) then the prefix and value must be added as separate command line arguments; if false, prefix and value must be concatenated into a single command line argument.
itemSeparator: [character] Join the array elements into a single string with the elements separated by by itemSeparator.
valueFrom: [characterOrExpression] If valueFrom is a constant string value, use this as the value and apply the binding rules above. If valueFrom is an expression, evaluate the expression to yield the actual value to use to build the command line and apply the binding rules above. If the inputBinding is associated with an input parameter, the "context" of the expression will be the value of the input parameter. When a binding is part of the CommandLineTool.arguments field, the valueFrom field is required.
