    Metadata

    CreateFiles does not propagate metadata from left to right or from right to left.

    This component has metadata template available. The templates of CreateFiles are described in Details. See details on metadata templates.

    CreateFiles Attributes

    Attribute Req Description Possible values

    Basic

    File URL

    yes[1]

    Path to the file or directory to be created (see Supported URL Formats for File Operations). If it ends with a slash ('/'), it denotes that a directory should be created, which can also be specified using the Create as directory attribute.

    Create as directory

    no

    Specifies that directories should be created instead of regular files.

    false (default) | true

    Create parent directories

    no

    Attempt to create non-existing parent directories.

    false (default) | true

    Last modified date

    no

    Set the last modified date of existing and newly created files to the specified value. Format of the date is defined in the DEFAULT_DATETIME_FORMAT property (Engine Configuration).

    Input mapping

    [2]

    Defines mapping of input records to the component attributes.

    Output mapping

    [2]

    Defines mapping of results to the standard output port.

    Error mapping

    [2]

    Defines mapping of errors to the error output port.

    Redirect error output

    no

    If enabled, errors will be sent to the standard output port instead of the error port.

    false (default) | true

    Verbose output

    no

    If enabled, one input record may cause multiple records to be sent to the output (e.g. as a result of wildcard expansion). Otherwise, each input record will yield just one cumulative output record.

    false (default) | true

    Advanced

    Stop processing on fail

    no

    By default, a failure causes the component to skip all subsequent input records and send the information about skipped input records to the error output port. This behavior can be turned off by this attribute. Note: this function works only if an edge is connected to the component’s error port.

    true (default) | false

    1

     The attribute is required, unless specified in the Input mapping.

    2

     Required if the corresponding edge is connected.

    Details

    Editing any of the Input, Output or Error mapping opens the Transform Editor.

    Output mapping

    The editor allows you to map the results and the input data to the output port.

    If Output mapping is empty, fields of the input record and result record are mapped to the output by name.

    Field Name Type Description

    fileURL

    string

    URL of the target file or directory.

    result

    boolean

    True if the operation has succeeded (can be false when Redirect error output is enabled).

    errorMessage

    string

    If the operation has failed, the field contains the error message (used when Redirect error output is enabled).

    stackTrace

    string

    If the operation has failed, the field contains the stack trace of the error (used when Redirect error output is enabled).

    Error mapping

    The editor allows you to map the errors and the input data to the error port.

    If Error mapping is empty, fields of the input record and result record are mapped to the output by name.

    Field Name Type Description

    result

    boolean

    Will always be set to false.

    errorMessage

    string

    The error message.

    stackTrace

    Examples

    Touching the File with CreateFiles

    Create file touch_me.txt. If the file exists, update the last modification time.

    Solution

    Use attributes .

    Attribute Value

    File URL

    ${DATATMP_DIR}/touch_me.txt

    Input mapping

    See the code below

    function integer transform() {
        $out.0.modifiedDate = today();
    
        return ALL;
    }

    You can optionally set Create parent directories to true.
