Reading a File
You can use the Filesystem adapter to read data from a file in the filesystem.
Reading Line By Line
Using the readLine operation of the Filesystem adapter, you can read a file line by line.
Name | Type | Direction | Description |
---|---|---|---|
name | String | in | Fully qualified file name of the file you want to close, including the path. When using the Windows style with backward slashes "\" you have to be aware that you need to escape this character. The escape character is also the "\". |
The path and file name of the file you want to access can be given dynamically via input parameter name, or statically via the definitions of an alias.
Reading a Complete File or Parts
Using the read operation of the Filesystem adapter, you can read a complete file in once, or specific parts of it.
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 need to 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.in | Integer | in | 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. |
length.out | Integer | 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). |
The path and file name of the file you want to access can be given dynamically via input parameter name, or statically via the definitions of an alias. If you do not want to read the complete file, provide a starting position in parameter position and/or a snippet size in parameter length. You can use this parameters separately or in combination.
Closing a File
On end of the service request, all files that have been used with the Filesystem adapter are closed automatically. In some cases, it may be helpful to manually close a file (e.g. if you want to rename or push the file).
You can close a file using the close operation of the Filesystem adapter.
Name | Type | Direction | Description |
---|---|---|---|
name | String | in | Fully qualified file name of the file you want to close, including the path. When using the Windows style with backward slashes "\" you have to be aware that you need to escape this character. The escape character is also the "\". |
The path and file name of the file you want to close can be given dynamically via input parameter name, or statically via the definitions of an alias.
