Field Summary

Fields

Modifier and Type	Field	Description
private static java.util.Map<java.lang.String,ScmFileStatus>	IDENTIFIERS	A list of known keywords from hg.
private static int	MAX_STDERR_SIZE	Number of lines to keep from Std.Err This size is set to ensure that we capture enough info but still keeps a low memory footprint.
private static java.util.Map<java.lang.String,java.lang.String>	MESSAGES	A list of known message prefixes from hg.
private java.util.List<java.lang.String>	stderr	A list of the MAX_STDERR_SIZE last errors or warnings.

Method Summary

Modifier and Type	Method	Description
void	consumeLine(java.lang.String line)
void	doConsume(ScmFileStatus status, java.lang.String trimmedLine)
java.lang.String	getStdErr()	Warnings and errors is usually printed out in Std.Err, thus for derived consumers operating on Std.Out this would typically return an empty string.
private static java.lang.String	processInputForKnownIdentifiers(java.lang.String line)
private boolean	processInputForKnownMessages(java.lang.String line)
