estimatedLength

private final int estimatedLength

Constructor Detail

ObjectEncoderOutputStream

public ObjectEncoderOutputStream(java.io.OutputStream out)

Creates a new ObjectOutput with the estimated length of 512 bytes.

Parameters:

out - the OutputStream where the serialized form will be written out

ObjectEncoderOutputStream

public ObjectEncoderOutputStream(java.io.OutputStream out,
                                 int estimatedLength)

Creates a new ObjectOutput.

Parameters:

out - the OutputStream where the serialized form will be written out

estimatedLength - the estimated byte length of the serialized form of an object. If the length of the serialized form exceeds this value, the internal buffer will be expanded automatically at the cost of memory bandwidth. If this value is too big, it will also waste memory bandwidth. To avoid unnecessary memory copy or allocation cost, please specify the properly estimated value.
