All Implemented Interfaces:
LogFormat
public class Log4jLogFormat extends AbstractRegexLogFormat
Describes the format of a log4j log file. Should use the same string specified in the log4j.properties file for *.layout.ConversionPattern as the format pattern. See org.apache.log4j.EnhancedPatternLayout for more information on valid format patterns.

  • Field Details

  • Constructor Details

    • Log4jLogFormat

      public Log4jLogFormat()
      Create a log format for accessing log4j log data.

    • Log4jLogFormat

      public Log4jLogFormat(String formatPattern)
      Create a log format for accessing log4j log data.
      Parameters:
      formatPattern - the log4j pattern that determines the schema

  • Method Details

    • setCustomLevelDefinitions

      public void setCustomLevelDefinitions(List<String> customLevelDefinitions)
      Sets the custom level definitions. The default level names are: TRACE, DEBUG, INFO, WARN, ERROR, FATAL
      Parameters:
      customLevelDefinitions - the custom level definition list

    • getCustomLevelDefinitions

      public List<String> getCustomLevelDefinitions()
      Gets the custom level definitions.
      Returns:
      the list of custom level names

    • setFormatPattern

      public void setFormatPattern(String formatPattern)
      Description copied from class: AbstractRegexLogFormat
      Set the value used for the log format pattern
      Specified by:
      setFormatPattern in interface LogFormat
      Overrides:
      setFormatPattern in class AbstractRegexLogFormat
      Parameters:
      formatPattern - the value to use as the format pattern

    • 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

    • createParser

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