Examples of org.apache.sling.scripting.javascript.io.EspReader

The nice thing about this reader is, that the line numbers of the resulting stream match the line numbers of the matching contents of the input stream. Due to the insertion of write() calls, column numbers will not necessarily match, though. This is especially true if you mix ECMA code tags (<% %>) with template text on the same line.

For maximum performance it is advisable to not create the EspReader with a plain FileReader or InputStreamReader but rather with a BufferedReader based on one of the simpler Readers. The reasons for this is, that we call the base reader character by character. This in turn is not too performing if the base reader does not buffer its input.
