com.orientechnologies.orient.core.record.ORecordAbstract

com.orientechnologies.orient.core.record.impl.ORecordBytes

All Implemented Interfaces:

OIdentifiable, ORecordElement, OBlob, ORecord, OSerializableStream, Serializable, Comparable<OIdentifiable>, Comparator<OIdentifiable>

Direct Known Subclasses:

ORecordBytesLazy

public class ORecordBytes
extends ORecordAbstract
implements OBlob

The rawest representation of a record. It's schema less. Use this if you need to store Strings or byte[] without matter about the content. Useful also to store multimedia contents and binary files. The object can be reused across calls to the database by using the reset() at every re-use.

Method Detail

reset

public ORecordBytes reset(byte[] iSource)

copy

public ORecordBytes copy()

Description copied from interface: ORecord

Creates a copy of the record. All the record contents are copied.

Specified by:

copy in interface ORecord

Returns:

The Object instance itself giving a "fluent interface". Useful to call multiple methods in chain.

fromStream

public ORecordBytes fromStream(byte[] iRecordBuffer)

Description copied from interface: OSerializableStream

Unmarshalls the object. Fills the current object with the values contained in the byte array representation restoring a previous state. Usually byte[] comes from the storage or network.

Specified by:

fromStream in interface OSerializableStream

Overrides:

fromStream in class ORecordAbstract

Parameters:

iRecordBuffer - byte array representation of the object

Returns:

The Object instance itself giving a "fluent interface". Useful to call multiple methods in chain.

clear

public ORecordAbstract clear()

Description copied from interface: ORecord

All the fields are deleted but the record identity is maintained. Use this to remove all the document's fields.

Specified by:

clear in interface ORecord

Overrides:

clear in class ORecordAbstract

Returns:

The Object instance itself giving a "fluent interface". Useful to call multiple methods in chain.

toStream

public byte[] toStream()

Description copied from interface: OSerializableStream

Marshalls the object. Transforms the current object in byte[] form to being stored or transferred over the network.

Specified by:

toStream in interface OSerializableStream

Overrides:

toStream in class ORecordAbstract

Returns:

The byte array representation of the object

See Also:

OSerializableStream.fromStream(byte[])

getRecordType

public byte getRecordType()

Specified by:

getRecordType in class ORecordAbstract

setup

protected void setup()

Overrides:

setup in class ORecordAbstract

fromInputStream

public int fromInputStream(InputStream in)
                    throws IOException

Reads the input stream in memory. This is less efficient than fromInputStream(InputStream, int) because allocation is made multiple times. If you already know the input size use fromInputStream(InputStream, int).

Specified by:

fromInputStream in interface OBlob

Parameters:

in - Input Stream, use buffered input stream wrapper to speed up reading

Returns:

Buffer read from the stream. It's also the internal buffer size in bytes

Throws:

IOException

fromInputStream

public int fromInputStream(InputStream in,
                           int maxSize)
                    throws IOException

Reads the input stream in memory specifying the maximum bytes to read. This is more efficient than fromInputStream(InputStream) because allocation is made only once.

Specified by:

fromInputStream in interface OBlob

Parameters:

in - Input Stream, use buffered input stream wrapper to speed up reading

maxSize - Maximum size to read

Returns:

Buffer count of bytes that are read from the stream. It's also the internal buffer size in bytes

Throws:

IOException - if an I/O error occurs.

toOutputStream

public void toOutputStream(OutputStream out)
                    throws IOException

Specified by:

toOutputStream in interface OBlob

Throws:

IOException
