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.
fileEncoding		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.
encoding	Specify the encoding of the file.	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. The resource can be replaced changing the resource path in the File System Adapter settings of the xUML service. If resource is specified neither file nor encoding can be overridden dynamically. See Importing File Resources for more information on importing resources and xUML Service Settings for more information on changing the settings of a service.

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 "\". To avoid this, use forward slashes with Windows as well.
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 "\". To avoid this, use forward slashes with Windows as well.
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 "\". To avoid this, use forward slashes with Windows as well.
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
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 "\". To avoid this, use forward slashes with Windows as well.
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.

Action "status"

Name	Type	Direction	Description
name	String	in	Fully qualified file name of the file/directory 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 "\". To avoid this, use forward slashes with Windows as well.
type	String	out	Type of accessed element (File or Directory).
size	Integer	out	Size of the file in Bytes. size is meaningless for directories, as it is not the combined size of all contained files and subfolders, but rather some constant defined by the operating system (e.g. 0 or 4096).
accessTime	DateTime	out	Timestamp when the file/directory was accessed for the last time.
creationTime	DateTime	out	Timestamp when the file/directory was created.
modificationTime	DateTime	out	Timestamp when the file/directory was modified for the last time.
