Classe: ChainReaderHelper  - X-Ref

Process a FilterReader chain.

Here, the interesting method is 'getAssembledReader'.
The purpose of this one is to create a simple Reader object which
apply all filters on another primary Reader object.

For example : In copyFile (phing.util.FileUtils) the primary Reader
is a FileReader object (more accuratly, a BufferedReader) previously
setted for the source file to copy. So, consider this filterchain :

<filterchain>
<stripphpcomments />
<linecontains>
<contains value="foo">
</linecontains>
<tabtospaces tablength="8" />
</filterchain>

getAssembledReader will return a Reader object wich read on each
of these filters. Something like this : ('->' = 'which read data from') :

[TABTOSPACES] -> [LINECONTAINS] -> [STRIPPHPCOMMENTS] -> [FILEREADER]
(primary reader)

So, getAssembledReader will return the TABTOSPACES Reader object. Then
each read done with this Reader object will follow this path.

Hope this explanation is clear :)
