The default value to use for this parameter if the parameter is missing from the input object, or if the value of the parameter in the input object is null. Default values are applied before evaluating expressions (e.g. dependent valueFrom fields).
A documentation string for this type, or an array of strings which should be concatenated.
Only valid when type: File or is an array of items: File. This must be one or more IRIs of concept nodes that represents file formats which are allowed as input to this parameter, preferrably defined within an ontology. If no ontology is available, file formats may be tested by exact match.
The unique identifier for this parameter object.
Describes how to handle the inputs of a process and convert them into a concrete form for execution, such as command line parameters.
A short, human-readable label of this object.
Only valid when type: File or is an array of items: File. Provides a pattern or expression specifying files or directories that must be included alongside the primary file. All listed secondary files must be present. An implementation may fail workflow execution if an expected secondary file does not exist. If the value is an expression, the value of self in the expression must be the primary input or output File object to which this binding applies. The basename, nameroot and nameext fields must be present in self. For CommandLineTool outputs the path field must also be present. The expression must return a filename string relative to the path to the primary File, a File or Directory object with either path or location and basename fields set, or an array consisting of strings or File or Directory objects. It is legal to reference an unchanged File or Directory object taken from input as a secondaryFile. To work on non-filename-preserving storage systems, portable tool descriptions should avoid constructing new values from location, but should construct relative references using basename or nameroot instead. If a value in secondaryFiles is a string that is not an expression, it specifies that the following pattern should be applied to the path of the primary file to yield a filename relative to the primary File: 1. If string begins with one or more caret ^ characters, for each caret, remove the last file extension from the path (the last period . and all following characters). If there are no file extensions, the path is unchanged. 2. Append the remainder of the string to the end of the file path.
Only valid when type: File or is an array of items: File. A value of true indicates that the file is read or written sequentially without seeking. An implementation may use this flag to indicate whether it is valid to stream file contents using a named pipe. Default: false.
Specify valid types of data that may be assigned to this parameter.
An input parameter for a CommandLineTool.
