Stereotype Attributes
DirectoryAlias
| Attribute | Description | Allowed Values / Example | |
|---|---|---|---|
| directory | Specify a path to a directory. This directory will be treated as a base directory. It will be either used directly (for a Filesystem adapter operating directly on directories), or as a base directory for a path segment given by a dynamic file name parameter. It is not possible to jump out of the base directory by ../../aDirectory tricks. The base directory can only be changed in the service settings on the Bridge. | tmp/Export | |
| fileEncoding | Specify the default encoding be used with the directory. This default encoding can be overwritten on adapter calls, using a dynamic encoding parameter, e.g. on Filesystem adapter calls reading lines, or with the Flat File adapter. | Refer to Charset Definitions for possible values. | |
| default, when empty | iso-8859-1 | ||
| Designer default | utf-8 | ||

| length | Integer | in/out | Length (in Bytes) of the snippet of the file you want to read. The actual length of the read data is given back (e.g. on file end). |
| data | Blob | out | Content that has been read. |
readLine
| Name | Type | Direction | Description |
|---|---|---|---|
| name | String | in | Fully qualified file name of the file you want to read, including the path. |
| encoding | String | in | Encoding of the file. Default encoding is iso-8859-1. For a list of possible encodings see Charset Definitions . |
| line | String | out | File content of the line that has been read. On file end, line is NULL. |
| length | Integer | out | Length (in Bytes) of the line that has been read. On file end, length is 0. |

append
You can use operation append in two modes:
If mode is empty or set to append, the content stored in data will be appended to the file specified in name. If the file does not exist, it will be created.
If mode is set to overwrite, the file specified in name will be overwritten with the content stored in data. If the file does not exist, it will be created.
overwrite will only be applied to the first append. All subsequent appends (e.g. in a loop) automatically get mode append.
