Examples of com.ericsson.otp.erlang.OtpErlangLong

com.ericsson.otp.erlang.OtpErlangLong
Provides a Java representation of Erlang integral types. Erlang does not distinguish between different integral types, however this class and its subclasses {@link OtpErlangByte}, {@link OtpErlangChar}, {@link OtpErlangInt}, and {@link OtpErlangShort} attempt to map the Erlang types onto the variousJava integral types. Two additional classes, {@link OtpErlangUInt} and{@link OtpErlangUShort} are provided for Corba compatibility. See thedocumentation for IC for more information.
