GlassfishLogFormat

public GlassfishLogFormat()

Create a log format for accessing Glasssfish log data.

GlassfishLogFormat

public GlassfishLogFormat(String formatPattern)

Create a log format for accessing Glassfish log data.

Parameters:

formatPattern - the timestamp format to use

Method Detail

getType

public RecordTokenType getType()

Description copied from interface: LogFormat

Gets the record type associated with the format. Records produced by the associated parser or consumed by the associated formatter will be of this type.

For many formats, this may be derived from a schema object describing the format layout.

Returns:

the format's record type

getSchema

public RecordTextSchema<?> getSchema()

Description copied from class: AbstractRegexLogFormat

Gets the record schema of the source.

Specified by:

getSchema in class AbstractRegexLogFormat

Returns:

the record schema of the source

refreshSchema

protected void refreshSchema()

Description copied from class: AbstractRegexLogFormat

Refresh and recalculate the schema. This is usually done after changing a setting.

Specified by:

refreshSchema in class AbstractRegexLogFormat

isSplittable

public boolean isSplittable()

Description copied from interface: LogFormat

Indicates if the format supports parsing of subsections of a file.

A format should only return true if it can, at least in some situations, support this sort of parsing. If a format requires reading the entire file, it must return false.

If a format is not splittable, a file in the format cannot be parsed in parallel; however, individual files can still be parsed independently in parallel, as when reading the contents of a directory or using a file globbing pattern.

Specified by:

isSplittable in interface LogFormat

Overrides:

isSplittable in class AbstractRegexLogFormat

Returns:

true if the format supports parsing only a portion of the file, false otherwise

analyzeFormat

public FormatAnalyzer.FormatAnalysis analyzeFormat(Reader input)
                                            throws IOException,
                                                   ParseException

Description copied from interface: LogFormat

Creates the analysis object based on the provided input.

Specified by:

analyzeFormat in interface LogFormat

Overrides:

analyzeFormat in class AbstractRegexLogFormat

Parameters:

input - the input source to analyze

Returns:

the analysis object

Throws:

IOException

ParseException

setAnalysis

public LogFormat setAnalysis(FormatAnalyzer.FormatAnalysis analysis)

Description copied from interface: LogFormat

Sets the analysis object to use to determine meta-data.

Specified by:

setAnalysis in interface LogFormat

Overrides:

setAnalysis in class AbstractRegexLogFormat

Parameters:

analysis - the analysis object

createParser

public DataFormat.DataParser createParser(ParsingOptions options,
                                          CharsetEncoding charEncoding,
                                          String newline)
