compose

public static <T> ch.qos.logback.core.Appender<T> compose(ch.qos.logback.core.Appender<T> one,
                                                          ch.qos.logback.core.Appender<T> two)

Factory method used to compose two Appender objects into a Composite Appender.

Type Parameters:

T - type of Appender to compose.

Parameters:

one - first Appender to compose.

two - second Appender to compose.

Returns:

Appender one if Appender two is null; Return Appender two if Appender one is null. Otherwise, return a Composite Appender composed of Appender one and Appender two.

Type Parameters:

T - type of the logging events processed by the Appenders.

Parameters:

appenders - array of Appenders to compose; may be null.

Returns:

a composition of the array of Appenders; returns null if the array is empty.

Type Parameters:

T - type of the logging events processed by the Appenders.

Parameters:

appenders - Iterable of Appenders to compose; may be null.
