ObjectStreamConstants

PROTOCOL_VERSION_1

static val PROTOCOL_VERSION_1: Int

A Stream Protocol Version.

All externalizable data is written in JDK 1.1 external data format after calling this method. This version is needed to write streams containing Externalizable data that can be read by pre-JDK 1.1.6 JVMs.

Value: 1

PROTOCOL_VERSION_2

static val PROTOCOL_VERSION_2: Int

A Stream Protocol Version.

This protocol is written by JVM 1.2. Externalizable data is written in block data mode and is terminated with TC_ENDBLOCKDATA. Externalizable class descriptor flags has SC_BLOCK_DATA enabled. JVM 1.1.6 and greater can read this format change. Enables writing a nonSerializable class descriptor into the stream. The serialVersionUID of a nonSerializable class is set to 0L.

Value: 2

SC_BLOCK_DATA

static val SC_BLOCK_DATA: Byte

Bit mask for ObjectStreamClass flag. Indicates Externalizable data written in Block Data mode. Added for PROTOCOL_VERSION_2.

Value: 8

SC_ENUM

static val SC_ENUM: Byte

Bit mask for ObjectStreamClass flag. Indicates class is an enum type.

Value: 16

SC_EXTERNALIZABLE

static val SC_EXTERNALIZABLE: Byte

Bit mask for ObjectStreamClass flag. Indicates class is Externalizable.

Value: 4

SC_SERIALIZABLE

static val SC_SERIALIZABLE: Byte

Bit mask for ObjectStreamClass flag. Indicates class is Serializable.

Value: 2

SC_WRITE_METHOD

static val SC_WRITE_METHOD: Byte

Bit mask for ObjectStreamClass flag. Indicates a Serializable class defines its own writeObject method.

Value: 1
