Method Detail

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

and(Marker)

writeTo

public abstract void writeTo(com.fasterxml.jackson.core.JsonGenerator generator)
                      throws IOException

Writes the data associated with this marker to the given JsonGenerator.

Parameters:

generator - the generator to which to write the output of this marker.

Throws:

IOException - if there was an error writing to the generator

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().

Overrides:

toString in class LogstashBasicMarker

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.
