com.reduxrobotics.frames.ByteArrayFrame<T>

public class ByteArrayFrame<T>
extends Frame<T>

Implements an object-holding Frame backed by a byte array. This avoids creation of new objects by only converting to objects when the value is requested.

Constructor Details

ByteArrayFrame

public ByteArrayFrame(int capacity,
 double timestamp,
 T defaultData,
 ByteArrayFrame.ByteArrayToType<T> conversion)

Instantiates a new ByteArrayFrame.

Parameters:

capacity - The capacity of the byte array value held.

timestamp - The timestamp the update happened at.

defaultData - An instance of the object to return before the first update happens.

conversion - A function that takes in a double and converts it to the final datatype.

Method Details

getValue

public T getValue()

Description copied from class: Frame

Returns the value of the data frame.

Specified by:

getValue in class Frame<T>

Returns:

the value the data frame holds.

hasData

public boolean hasData()

Returns if this frame has data.

Specified by:

hasData in class Frame<T>

Returns:

if this frame's data can be considered valid

clearData

public void clearData()

Flag that this frame's data is not valid.

getData

public byte[] getData()

Gets the underlying byte array data.

Returns:

the byte array data as a type.

updateData

public void updateData(byte[] data,
 double timestamp)

Update the ByteArrayFrame with new byte array data.

Parameters:

data - the new data to update with

timestamp - the timestamp at which it occured
