RegexpLineParser

public RegexpLineParser(java.lang.String warningPattern,
                        java.lang.String name)

Parameters:

warningPattern - pattern of compiler warnings.

name - name of the parser

RegexpLineParser

public RegexpLineParser(java.lang.String warningPattern,
                        java.lang.String name,
                        boolean isStringMatchActivated)

Creates a new instance of RegexpParser. Uses a single line matcher.

Parameters:

warningPattern - pattern of compiler warnings.

name - name of the parser

isStringMatchActivated - determines if a line is checked for a string existence before the regexp is applied

Method Detail

parse

public java.util.Collection<hudson.plugins.analysis.util.model.FileAnnotation> parse(java.io.Reader file)
                                                                              throws java.io.IOException

Parses the specified input stream for compiler warnings using the provided regular expression.

Parameters:

file - the file to parse

Returns:

the collection of annotations

Throws:

java.io.IOException - Signals that an I/O exception has occurred.

isLineInteresting

protected boolean isLineInteresting(java.lang.String line)

Returns whether the specified line is interesting. Each interesting line will be handled by the defined regular expression. Here a parser can 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.
