    Deprecated.
    Use resolveReferencedFiles(WorkflowNode, IReferencedFileList, IFileSearchOptions).
    
    Returns the file represented by the given descriptor. When the files of a previous node are referenced and that node was executed multiple times, all files from all executions of that node are returned.
    This will throw when ISingleFileProviding.getResource() is null. If the resource is optional, check for that case before you call this method.
    The returned file(s) may be shared with other nodes and should be thought of as read-only. You may read the file(s), but should neither modify nor delete the file(s). You should also not write other files to the directory of the returned file(s), use targetDirForNode(WorkflowNode, String...) or randomTempDirForNode(WorkflowNode, String...) when you need write output our temporary files.
    
    Parameters:
    
    node - Node that requested the files. Used to determine an appropriate temporary directory.
    
    singleFile - File descriptor for a single file.
    
    options - Options for searching files. When null, a reasonable default is used.
    
    Returns:
    
    The file represented by the given descriptor. null when no file is found.
    
    Throws:
    
    MalformedURLException - When a URL resource is selected and the URL is invalid.
    
    FileNotFoundException - When the given singleFile has not resource selected; or when no matching resource could be found; such as when no file for an upload element with the configured name exists; or when the selected workflow node was not executed or does not exist anymore.
    
    FileFormatException - When searching for a form record attachment and one is found, but it does not match the filter (extension) configured by the user.
    
    IOException - When a file could not be read from the file system or a resource could not be read from the network.
    
    IllegalArgumentException - When the given ISingleFileProviding is invalid (and should not have passed the workflow validation process).

    Returns all files from given triggers, limited to triggers that are currently firing. Triggers that did not create a file or directory are omitted.
    When a trigger fired multiple times, only the current firing is considered.
    The returned file(s) may be shared with other elements and should be thought of a read-only. You may read the file(s), but should neither modify nor delete the file(s). You should also not write other files to the directory of the returned file(s), use targetDirForTrigger(WorkflowTrigger, String...) or randomTempDirForTrigger(WorkflowTrigger, String...) when you need write output our temporary files.
    
    Parameters:
    
    currentTriggers - Previous triggers for which to retrieve the files.
    
    Returns:
    
    All files or directories that were created by the specified previous triggers.

```
    Returns the attachments represented by the given descriptor. When the attachments of a previous node are referenced and that node was executed multiple times, all attachments from all executions of that node are returned.
    Different actions may require errors to be handled differently, so this method never throws any exceptions. Use the returned IResolvedAttachmentList instance to handle errors. In particular, if you wish to use the standard error behavior, you can use collectResult together with the standardAttachmentErrorsSingle or standardAttachmentErrorsMultiple method from INodeExecutionParams that are passed to the execute method.
    
    Parameters:
    
    node - Node that requested the attachments. Used as the context for resolving attachments, e.g. when the node is within a loop.
    
    attachmentList - Attachment descriptor with the attachment references to resolve.
    
    options - Options for searching attachments. When null, a reasonable default is used.
    
    Returns:
    
    The resolved attachments.

                                         IFileSearchOptions options)
```
    Returns the files represented by the given descriptor. When the files of a previous node are referenced and that node was executed multiple times, all files from all executions of that node are returned.
    Different actions may require errors to be handled differently, so this method never throws any exceptions. Use the returned IResolvedFileList instance to handle errors. In particular, if you wish to use the standard error behavior, you can use collectResult together with the standardFileErrorsSingle or standardFileErrorsMultiple method from INodeExecutionParams that are passed to the execute method.
    The returned file(s) may be shared with other nodes and should be thought of as read-only. You may read the file(s), but should neither modify nor delete the file(s). You should also not write other files to the directory of the returned file(s), use targetDirForNode(WorkflowNode, String...) or randomTempDirForNode(WorkflowNode, String...) when you need write output our temporary files.
    
    Parameters:
    
    node - Node that requested the files. Used e.g. to determine an appropriate temporary directory.
    
    fileList - File descriptor with the file references to resolve.
    
    options - Options for searching files. When null, a reasonable default is used.
    
    Returns:
    
    The resolved multi files, with the original file names and the directory containing the files.

    Compared with sourceDirForNode(WorkflowNode, String...), this method interprets the last item of subDirs as a file and does not attempt to create a directory for that. E.g. if you call sourceDirForNode(node, "foo", "bar.txt", it would attempt to create the directories foo and bar.txt. This method only creates the foo directory.
    
    Parameters:
    
    node - The node for which the source directory should be returned.
    
    pathSegments - Optional path segments to access a subdirectory or the source directory. The last item must be the file name.
    
    Returns:

```
    Shortcut for getTempFileForTrigger(trigger, "source"). Creates a file in the default directory for storing intermediate files that are required only during execution of the trigger, but are not returned and made available to other triggers. When a path is given, this method ensures that the returned file is inside the source directory, even when the given path contains navigation symbols such as ...
    Compared with sourceDirForTrigger(WorkflowTrigger, String...), this method interprets the last item of subDirs as a file and does not attempt to create a directory for that. E.g. if you call sourceDirForTrigger(trigger, "foo", "bar.txt", it would attempt to create the directories foo and bar.txt. This method only creates the foo directory.
    
    Parameters:
    
    trigger - The trigger for which the source directory should be returned.
    
    pathSegments - Optional path segments to access a subdirectory or the source directory. The last item must be the file name.
    
    Returns:
    
    A file within the temporary source directory for the given trigger.
    
    Throws:
    
    IOException - When intermediate non-existing directories could not be created.

```
    Starting at the given base directory, accesses the given subdirectories, creates that subdirectory if necessary, and returns a file corresponding to that subdirectory.
    Each item in the given subdirectory is sanitized and should not contain path separators or relative paths. When the subDirs contains n non-empty items, it is guaranteed that the baseDir is the nth parent of the returned directory. So for example:
    // "/tmp/foo" subDirectory("/tmp", "foo"); // "/tmp/bar" subDirectory("/tmp", "../bar"); // "/tmp/bar/baz" subDirectory("/tmp", "../bar", "baz");
    Parameters:
    
    baseDir - Base directory.
    
    subDirs - A list of subdirectories. Should be an absolute path. Empty names are ignored, e.g. passing ["foo", "", "bar] is the same as passing ["foo", "bar].
    
    Returns:
    
    The file pointing to the path corresponding to <dir>/subDirs[0]/subDirs[1]/.../subDirs[len - 1]. Non-existing directories will be created.
