Class PersistentHttpStream

java.lang.Object

java.io.InputStream

com.sedmelluq.discord.lavaplayer.tools.io.SeekableInputStream

com.sedmelluq.discord.lavaplayer.tools.io.PersistentHttpStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Direct Known Subclasses:

HeartbeatingHttpStream, YoutubePersistentHttpStream

public class PersistentHttpStream
extends SeekableInputStream
implements java.lang.AutoCloseable

Use an HTTP endpoint as a stream, where the connection resetting is handled gracefully by reopening the connection and using a closed stream will just reopen the connection.

Constructor Detail

PersistentHttpStream

public PersistentHttpStream(HttpInterface httpInterface,
                            java.net.URI contentUrl,
                            java.lang.Long contentLength)

Parameters:

httpInterface - The HTTP interface to use for requests

contentUrl - The URL of the resource

contentLength - The length of the resource in bytes

Method Detail

checkStatusCode

public int checkStatusCode()
                    throws java.io.IOException

Connect and return status code or return last status code if already connected. This causes the internal status code checker to be disabled, so non-success status codes will be returned instead of being thrown as they would be otherwise.

Returns:

The status code when connecting to the URL

Throws:

java.io.IOException - On IO error

getCurrentResponse

public org.apache.http.HttpResponse getCurrentResponse()

Returns:

An HTTP response if one is currently open.

getConnectUrl

protected java.net.URI getConnectUrl()

useHeadersForRange

protected boolean useHeadersForRange()

connect

protected void connect(boolean skipStatusCheck)
                throws java.io.IOException

Throws:

java.io.IOException

createContentInputStream

public java.io.InputStream createContentInputStream(org.apache.http.HttpResponse response)
                                             throws java.io.IOException

Returns:

An InputStream implementation for the current http stream.
