All Implemented Interfaces:

Closeable, AutoCloseable

public class Dataset
extends IndirectDataset

A data set returned from the stream factory which includes a pool of data readers that are used to fetch data from the source when the data set is used to retrieve data not already in memory.

Extends Dataset

Created by StreamFactory. Since stream works with file directly a pool of readers is maintained until the dataset is closed. Class provides extra methods to check how many readers were created and how many are currently free to use. Use IndirectDataset instead, if you need access to the pool of readers, or use Dataset if not. This is only here for backwards compatibility

Constructor Detail

Dataset

public Dataset(String fileName,
               Date lastModified,
               Modes mode,
               boolean isTempFile)
        throws IOException

Creates a dataset object with a pool of readers used to retrieve data from the data file. Only useful in stram mode.

Parameters:

lastModified - Date and time the source data was last modified.

fileName - Valid path to the uncompressed data set file.

mode - Mode The mode of operation the data set will be using.

isTempFile - True if the file should be deleted when the source is disposed

Throws:

IOException - if there was a problem accessing data file.

Dataset

public Dataset(byte[] data,
               Modes mode)
        throws IOException

Parameters:

data - array of bytes to read from.

mode - The mode of operation the data set will be using.

Throws:

IOException - if there was a problem accessing data file.
