Constructor Detail

OtpErlangBinary

public OtpErlangBinary(byte[] bin)

Create a binary from a byte array

Parameters:

bin - the array of bytes from which to create the binary.

OtpErlangBinary

public OtpErlangBinary(OtpInputStream buf)
                throws OtpErlangDecodeException

Create a binary from a stream containing a binary encoded in Erlang external format.

Parameters:

buf - the stream containing the encoded binary.

Throws:

OtpErlangDecodeException - if the buffer does not contain a valid external representation of an Erlang binary.

OtpErlangBinary

public OtpErlangBinary(java.lang.Object o)

Create a binary from an arbitrary Java Object. The object must implement java.io.Serializable or java.io.Externalizable.

Parameters:

o - the object to serialize and create this binary from.

Method Detail

encode

public void encode(OtpOutputStream buf)

Convert this binary to the equivalent Erlang external representation.

Overrides:

encode in class OtpErlangBitstr

Parameters:

buf - an output stream to which the encoded binary should be written.

equals

public boolean equals(java.lang.Object o)

Determine if two binaries are equal. Binaries are equal if they have the same length and the array of bytes is identical.

Overrides:

equals in class OtpErlangBitstr

Parameters:

o - the binary to compare to.

Returns:

true if the byte arrays contain the same bytes, false otherwise.

clone

public java.lang.Object clone()

Overrides:

clone in class OtpErlangBitstr
