java.io.DataOutput
The DataOutput interface provides for converting data from any of the Java primitive types to a series of bytes and writing these bytes to a binary stream. There is also a facility for converting a String into modified UTF-8 format and writing the resulting series of bytes.
For all the methods in this interface that write bytes, it is generally true that if a byte cannot be written for any reason, an IOException is thrown. @author Frank Yellin @version 1.23, 05/23/06 @see java.io.DataInput @see java.io.DataOutputStream @since JDK1.0
org.apache.lucene.store.DataOutput
Abstract base class for performing write operations of Lucene's low-level data types.

- {@link org.eclipse.bpmn2.DataOutput#getOutputSetWithWhileExecuting Output Set With While Executing}
- {@link org.eclipse.bpmn2.DataOutput#getOutputSetRefs Output Set Refs}
- {@link org.eclipse.bpmn2.DataOutput#isIsCollection Is Collection}

org.lilyproject.bytes.api.DataOutput
The DataOutput converts primitive types to bytes and writes them to an underlying byte array.
The DataOutput maintains the position within the underlying byte[]. Every write call writes the value after the previous value.
The underlying byte[] is automatically resized, avoiding IOExceptions or OutOfBoundsExceptions.
This array can be retrieved by calling toByteArray().
A related {@link DataInput} should be created based on the byte[]created by a DataOutput.

Examples of java.io.DataOutput

        map.put(new Long(3L), new String("all"));
        t1.set(0, map);


        File file = File.createTempFile("Tuple", "put");
        FileOutputStream fos = new FileOutputStream(file);
        DataOutput out = new DataOutputStream(fos);
        t1.write(out);
        fos.close();


        FileInputStream fis = new FileInputStream(file);
        DataInput in = new DataInputStream(fis);
