public abstract class FastRegexpLineParser
extends RegexpLineParser

Parses an input stream line by line for compiler warnings using the provided regular expression. Multi-line regular expressions are not supported, each warning has to be one a single line. A parser must implement some fast checks (i.e. string or character comparisons) before the line parsing is started, see isLineInteresting(String).

Method Detail

findIssues

protected void findIssues(String content,
                          Report report)
                   throws ParsingCanceledException

Overrides:

findIssues in class RegexpParser

Parameters:

content - the content to scan

report - the report to add the new issues to

Throws:

ParsingCanceledException - Signals that the parsing has been aborted by the user

isLineInteresting

protected abstract boolean isLineInteresting(String line)

Returns whether the specified line is interesting. Each interesting line will be handled by the defined regular expression. Here a parser must implement some fast checks (i.e. string or character comparisons) in order to see if a required condition is met.

Parameters:

line - the line to inspect

Returns:

true if the line should be handed over to the regular expression scanner, false if the line does not contain a warning.
