CLOSED - Static variable in class datasource.DataSource

CONNECTED - Static variable in class datasource.DataSource

D

The data

dataBuffer - Variable in class datasource.DataSource

The data buffer between the local, reader thread and the client thread.

datarecord - package datarecord

DataRecord - Class in datarecord

For simplicity, all DataSource and DataSink classes use a single representation for data records in their buffers.

DataRecord(int) - Constructor for class datarecord.DataRecord

Create the record and initialize to empty.

DataRecordManager - Class in datarecord

Objects of this class allocate DataRecords.

DataRecordManager() - Constructor for class datarecord.DataRecordManager

datasource - package datasource

Creates a new DataSource.

DataSource.ReceiveHelper - Class in datasource

Helper class to implement reading thread.

DataSource.ReceiveHelper() - Constructor for class datasource.DataSource.ReceiveHelper

E

elapsedTime - Variable in class netapp.Client

A FileSource is a source that reads a file (sequentially);

FileSource(String) - Constructor for class datasource.FileSource

Open file for reading.

freeMap - Variable in class datarecord.DataRecordManager

To try to minimize Java effects, we cache DataRecords (to avoid creating a lot, which might require garbage collecting a lot).

freeRecord(DataRecord) - Method in class datarecord.DataRecordManager

Called when done using a DataRecord.

G

getNewRecord(int) - Method in class datarecord.DataRecordManager

Class factory -- returns a DataRecord.

Logger - Class in util

Utility class to write a log file.

Logger(String) - Constructor for class util.Logger

M

main(String[]) - Static method in class netapp.Client

main() handles the command line arguments, meaning it sets up the src and sink for the Client object.

mapKey - Variable in class datarecord.DataRecord

An instance variable of what would normally be a local variable.

mark() - Method in class util.StopWatch

Set the reference time to now.

mySize - Variable in class datasource.NullSource

mySize is how many bytes this Null source should send in total.

Helper function to print some statistics.

R

read(byte[], int) - Method in class datasource.DataSource

Reads up to maxLength bytes and returns them via argument buf, starting at position 0.

reader - Variable in class datasource.DataSource

The reader thread (fetches data from this object's source and puts it in dataBuffer).

readFromSrc(byte[], int) - Method in class datasource.DataSource

Perform actual read from file.

readFromSrc(byte[], int) - Method in class datasource.NetSource

Called by reader thread in DataSource object.

readFromSrc(byte[], int) - Method in class datasource.NullSource
