Join the array elements into a single string with the elements separated by by itemSeparator.
Only valid when type: File or is an array of items: File. Read up to the first 64 KiB of text from the file and place it in the "contents" field of the file object for use by expressions.
The sorting key. Default position is 0.
Command line prefix to add before the value.
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.
If ShellCommandRequirement is in the requirements for the current command, this controls whether the value is quoted on the command line (default is true). Use shellQuote: false to inject metacharacters for operations such as pipes. If shellQuote is true or not provided, the implementation must not permit interpretation of any shell metacharacters or directives.
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 value of self in the expression will be the value of the input parameter. Input parameter defaults (as specified by the InputParameter.default field) must be applied before evaluating the expression. When a binding is part of the CommandLineTool.arguments field, the valueFrom field is required.
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. - **string**: Add prefix and the string to the command line. - **number**: Add prefix and decimal representation to command line. - **boolean**: If true, add prefix to the command line. If false, add nothing. - **File**: Add prefix and the value of `File.path` to the command line. - **Directory**: Add prefix and the value of `Directory.path` to the command line. - **array**: If itemSeparator is specified, add prefix and the join the array into a single string with itemSeparator separating the items. Otherwise first add prefix, then recursively process individual elements. If the array is empty, it does not add anything to command line. - **object**: Add prefix only, and recursively add object fields for which inputBinding is specified. - **null**: Add nothing.
