File System Adapter Reference
This page explains the Filesystem Adapter in Bridge context. If you were looking for the same information regarding the PAS Designer, refer to Filesystem Adapter in the Designer guide.
Tagged Values
<<DirectoryAlias>>
Tagged Value | Description | Allowed Values | |
---|---|---|---|
directory | Specify a path to a directory. This directory will be treated as a base directory. It will be either used directly (for a File System 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. | Example: | ./tmp/testDirectory |
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 File System Adapter calls reading lines, or with the Flat File Adapter. | Refer to Charset Definitions for possible values. | |
default | iso-8859-1 |
<<FileAlias>>
Tagged Value | Description | Allowed Values | |
---|---|---|---|
file | Specify name and path of the file you want to access. | Example: | .tmp/testDirectory/testFile.txt |
encoding | Specify the encoding of the file. | Refer to Charset Definitions for possible values. | |
default | iso-8859-1 | ||
resource | Instead of a file, you can select a resource from the list of imported resources. The File System Adapter will then use the resource instead of file. If resource is specified neither file nor encoding can be overridden dynamically. |
Parameters File Handling
Action "read"
Name | Type | Direction | Description |
---|---|---|---|
name | String | in | Fully qualified file name of the file you want to read, including the path. When using the Windows style with backward slashes "\" you have to be aware that you have escape this character. The escape character is also the "\". |
position | Integer | in | Position (in Bytes) from which you want to start reading the file. |
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. |
Action "readLine"
Name | Type | Direction | Description |
---|---|---|---|
name | String | in | Fully qualified file name of the file you want to read, including the path. When using the Windows style with backward slashes "\" you have to be aware that you have escape this character. The escape character is also the "\". |
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. |
Action "write"
Name | Type | Direction | Description |
---|---|---|---|
name | String | in | Fully qualified file name of the file you want to write, including the path. When using the Windows style with backward slashes "\" you have to be aware that you have escape this character. The escape character is also the "\". |
position | Integer | in | Position (in Bytes) from which you want to start writing the file. |
data | Blob | Content you want to write to the file. | |
length | Integer | in | Length (in Bytes) of the data you want to write, if you want to only write part of the Blob. |
Action "append"
To action append, two modes can be applied:
- append
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. - overwrite
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.
Name | Type | Direction | Description |
---|---|---|---|

data | Blob | in | Content you want to write to the file. |
length | Integer | in | Length (in Bytes) of the data you want to append, if you want to only write part of the Blob. |
