java.io.DataInput
DataInput is an interface which declares methods for reading in typed data from a Stream. Typically, this stream has been written by a class which implements DataOutput. Types that can be read include byte, 16-bit short, 32-bit int, 32-bit float, 64-bit long, 64-bit double, byte strings, and UTF Strings. @see DataInputStream @see RandomAccessFile
org.apache.lucene.store.DataInput
Abstract base class for performing read operations of Lucene's low-level data types.
org.eclipse.bpmn2.DataInput
A representation of the model object 'Data Input'.
The following features are supported:
- {@link org.eclipse.bpmn2.DataInput#getInputSetWithOptional Input Set With Optional}
- {@link org.eclipse.bpmn2.DataInput#getInputSetWithWhileExecuting Input Set With While Executing}
- {@link org.eclipse.bpmn2.DataInput#getInputSetRefs Input Set Refs}
- {@link org.eclipse.bpmn2.DataInput#isIsCollection Is Collection}
- {@link org.eclipse.bpmn2.DataInput#getName Name}
@see org.eclipse.bpmn2.Bpmn2Package#getDataInput() @model extendedMetaData="name='tDataInput' kind='elementOnly'" @generated
org.lilyproject.bytes.api.DataInput
DataInput reads primitive types from a byte[] which has been encoded using the {@link DataOutput}
Every read call reads the next value from the underlying byte[].
The underlying byte[] can be larger than the part that the DataInput "views". All methods are relative to the view of the DataInput, except methods that refer to the "start position", which is the absolute position in the underlying byte[].
