void format(Appender downstream,
 A a,
 String path,
 Class<?> c,
 @Nullable Object o)
     throws E

Formats the object and then sends the results to the downstream appender. Will throw an NPE if parameter o is null.

Specified by:

format in interface Formatter

Type Parameters:

A - the appendable type

E - the appender exception type

Parameters:

downstream - the downstream appender to be used instead of the appendable directly

a - the appendable to be passed to the appender

path - the dotted mustache like path

c - the object class but is not guaranteed to be accurate. If it is not known Object.class will be used.

o - the object which maybe null

Throws:

format

default <A extends Output<E>,
E extends Exception>
void format(Appender downstream,
 A a,

 String s)
     throws E

Formats the object and then sends the results to the downstream appender. The default implementation passes natives through to the downstream appender. Will throw an NPE if parameter s is null.

Specified by:

format in interface Formatter

A - the appendable type

E - the appender exception type

Parameters:

downstream - the downstream appender to be used instead of the appendable directly

a - the appendable to be passed to the appender

path - the dotted mustache like path

s - String

Throws:

E - if the appender or appendable throws an exception
