In the presence of parameterised types whose names begin
with a capital letter and end with a less-than sign "<" that
introduces a type argument or a list of comma-separated type
arguments, followed by a greater-than sign ">", a variable
"g:java_highlight_generics" can be defined to have some
components of such types uniformly coloured (by picking
highlight groups for javaGenericsC{1,2}, javaWildcardBound).
For example,
------------------------------------------------------------
java.io.InputStream stream = java.io.InputStream.nullInputStream();
java.util.function.Function<String,
java.util.function.BiFunction<String, String, String>> updater =
property -> (oldValue, newValue) -> oldValue;
java.util.logging.LogManager.getLogManager()
.updateConfiguration(stream, updater);
------------------------------------------------------------
Note that the diamond form and explicit type arguments do
not qualify for this kind of recognition.
For example,
------------------------------------------------------------
new java.util.HashSet<>().<String>toArray(new String[0]);
------------------------------------------------------------
