FileHandler concept working with simple files.
With this handler you can get or set the specified file content.
URL format is :
file:/<path>
Possible options :
-

- if this option is append
then the specified
string will be appended to the file else the file conetent will be
overwrited with the specified string
-
requests
- use this option to specify how many times will
go the search in sublinks from the current path.
-
depth
- use this option to specify how deep will go the search
in sublink from the current path.
-
filter
- use this option to specify filter for your results.
Get the specified file content.
$file from "file:/dirNane/fileName"
print $file/content
Get the specified files name from specified directory recursively 5 times maximum 2 depth.
$files from "file:/dirName/" options "requests"=5 ,"depth"=2
each $file in $files do [
print $file@url]
Get the specified files name from specified directory recursively 5 times maximum 2 depth
where files have 'txt' extension.
$files from "file:/dirName/" options "requests"=5 ,"depth"=2, "filter"=Simplex.create("*.txt")
each $file in $files do [
print $file@url]

| Methods inherited from: URIHandler
|
| Parameters: |
| $url : | The url with which this FileHandler will be created. |
|
Creates a new FileHandler concept with the given $url.
| Parameters: |
| $url : | The uri which will be tested if it is acceptable by this handler. |
|
Returns true if the given $uri is acceptable by this handler, false
otherwise.

-- the result is --
true
Returns true.

]
]
-- the result is --

This is a test file
Returns the content of this FileHandler as String concept if the content type
is text or ByteArray concept otherwise.

| Parameters: |
| $options : | Contains a filter with which the returned content will be filtered. |
