Constructor Details

FramingEncodingContext

public FramingEncodingContext(Object rootobject,
 Object usercontext,
 List<jadex.common.transformation.traverser.ITraverseProcessor> preprocessors,
 ClassLoader classloader,
 SerializationConfig config)

Creates an encoding context.

Parameters:

usercontext - A user context.

preprocessors - The preprocessors.

classloader - The classloader.

Method Details

startObjectFrame

public void startObjectFrame(boolean fixedsize)

Starts an object frame when using a context with framing support.

Specified by:

startObjectFrame in interface IEncodingContext

Overrides:

startObjectFrame in class AbstractEncodingContext

Parameters:

fixedsize - If true, use fixed-size (integer) framing. Set true if the object being framed is expected to be larger than 127 bytes (same type of object MUST use either fixed OR variable framing).

stopObjectFrame

public void stopObjectFrame()

Stops an object frame when using a context with framing support.

Specified by:

stopObjectFrame in interface IEncodingContext

Overrides:

stopObjectFrame in class AbstractEncodingContext

writeByte

public void writeByte(byte b)

Description copied from interface: IEncodingContext

Writes a byte.

Parameters:

b - The byte.

write

public void write(byte[] b)

Description copied from interface: IEncodingContext

Writes a byte array.

Parameters:

b - The byte array.

toByteArray

public byte[] toByteArray()

Returns the current data buffer, trimmed to size.

Returns:

The buffer.

ensureSpace

protected void ensureSpace(int requiredsize)

Ensures sufficient space in buffer.

Parameters:

requiredsize - Required space in buffer.
