The arity of the map is the number of elements it contains. The keys and values can be retrieved as arrays and the value for a key can be queried.

object clj

(object)

This is a psuedo-constructor: OtpErlangObject doesn't provide a constructor method, but the object itself is needed for creating tuples, so this function simply returns OtpErlangObject.

pid clj

• the pid serial (Integer)
• the pid creation (Integer)

port clj

(port tag node id creation)

Provides a Java representation of an Erlang Port.

If one argument is passed, it must be of type OtpInputStream. If three arguments are passed, they must be:

• the node (String)
• the port id (Integer)

OtpErlangUInt and OtpErlangUShort (and thus types/unit and types/ushort) are provided for Corba compatibility.

string clj

(string arg)

Provides a Java representation of Erlang strings. Supplied argument may be any of:

• String
• OtpErlangList
• OtpInputStream (buffer)

tuple clj

(tuple arg)

(tuple array index count)

Provides a Java representation of Erlang tuples. Tuples are created from one or more arbitrary Erlang terms. If a single argument is passed, it may be:

• an OtpErlangObject, in which case a unary tuple will be created
• an array of OtpErlangObjects, in which case the tuple will have the same arity as the array that is passed
• an OtpInputStream (buffer)

Alternatively, a tuple may be created from a subset of an array of OtpErlangObjects by passing the array, the starting index (0-based), and the count (number of elements to include).

The arity of the tuple is the number of elements it contains. Elements are indexed from 0 to (arity-1) and can be retrieved individually by using the appropriate index.

uint clj

(uint arg)

See the docstring for #'types/int.

ushort clj

(ushort arg)

See the docstring for #'types/short.
