OtpErlangObject
public OtpErlangObject()
toString
public abstract java.lang.String toString()
- Overrides:
toString
in class java.lang.Object
- Returns:
- the printable representation of the object. This is usually
similar to the representation used by Erlang for the same type of
object.
encode
public abstract void encode(OtpOutputStream buf)
- Convert the object according to the rules of the Erlang external format.
This is mainly used for sending Erlang terms in messages, however it can
also be used for storing terms to disk.
- Parameters:
buf
- an output stream to which the encoded term should be
written.
decode
public static OtpErlangObject decode(OtpInputStream buf)
throws OtpErlangDecodeException
- Read binary data in the Erlang external format, and produce a
corresponding Erlang data type object. This method is normally used when
Erlang terms are received in messages, however it can also be used for
reading terms from disk.
- Parameters:
buf
- an input stream containing one or more encoded Erlang
terms.
- Returns:
- an object representing one of the Erlang data types.
- Throws:
OtpErlangDecodeException
- if the stream does not contain a valid representation
of an Erlang term.
equals
public abstract boolean equals(java.lang.Object o)
- Determine if two Erlang objects are equal. In general, Erlang objects are
equal if the components they consist of are equal.
- Overrides:
equals
in class java.lang.Object
- Parameters:
o
- the object to compare to.
- Returns:
- true if the objects are identical.
hashCode
public int hashCode()
- Overrides:
hashCode
in class java.lang.Object
doHashCode
protected int doHashCode()
clone
public java.lang.Object clone()
- Overrides:
clone
in class java.lang.Object
