    • and

      public <T extends LogstashMarker> T and(org.slf4j.Marker reference)
      Adds the given marker as a reference, and returns this marker.

      This can be used to chain markers together fluently on a log line. For example: 

      
import static net.logstash.logback.marker.Markers.*

logger.info(append("name1", "value1).and(append("name2", "value2")), "log message");
      Type Parameters:
      T - subtype of LogstashMarker
      Parameters:
      reference - The marker to add
      Returns:
      A marker with this marker and the given marker

    • with

      @Deprecated public <T extends LogstashMarker> T with(org.slf4j.Marker reference)
      Deprecated.
      Use and(Marker) instead
      Type Parameters:
      T - subtype of LogstashMarker
      Parameters:
      reference - The marker to add
      Returns:
      A marker with this marker and the given marker

    • writeTo

      public abstract void writeTo(JsonGenerator generator)
      Writes the data associated with this marker to the given JsonGenerator.
      Parameters:
      generator - the generator to which to write the output of this marker.

    • add

      public void add(org.slf4j.Marker reference)
      Specified by:
      add in interface org.slf4j.Marker

    • toString

      public String toString()
      Returns a String in the form of 
          self, reference1, reference2, ...

      Where self is the value returned by toStringSelf(), and reference* are the toString() values of any references.

      It is recommended that subclasses only override toStringSelf(), so that references are automatically included in the value returned from toString().

      Returns:
      a string representation of the object, which includes references

    • toStringSelf

      protected String toStringSelf()
      Returns a string representation of this object, without including any references.

      Subclasses should override toStringSelf() instead of toString(), since toString() will automatically include the toStringSelf() and references.

      Returns:
      a string representation of this object, without including any references.
