extern class JavaString

java :: JavaString

A standard Java string java.lang.String

Introduced properties

fun to_cstring: CString

java :: JavaString :: to_cstring

Get the string from Java and copy it to Nit memory

Redefined properties

redef type SELF: JavaString

java $ JavaString :: SELF

Type of this instance, automatically specialized in every class
redef fun to_s: String

java $ JavaString :: to_s

User readable representation of self.
