Class DefaultFilesystem

java.lang.Object

All Implemented Interfaces:

CollectionURIResolver, ModuleURIResolver, org.xml.sax.EntityResolver

public class DefaultFilesystem
extends AlternateFilesystem

This class provides an implementation for XProcFilesystem that support all required methods for 'file:', 'http:' and 'https:' and supports also sending http requests by using p:http-request. The basis functionally is provided by extending AlternateFileSystem while support for p:http-request is provided in this class.

Since this class heavily depends on Apache's Commons HttpClient(TM), you have to have the related jar-files on your class path. If you do not need support for p:http-request and/or do not want to have the Apache-classes on the class path, just switch to AlternateFilesystem as default in your configuration of MorganaXProc. The Apache jar files needed are:

• commons-codec-1.10.jar
• commons-logging-1.2.jar
• httpclient-4.5.6jar
• httpcore-4.4.10.jar

Constructor Detail

DefaultFilesystem

public DefaultFilesystem(XProcConfiguration config)
                  throws java.lang.ClassNotFoundException

Create a new DefaultFilesystem with redirection strategy 'default'. See explanation for DefaultFileSystem(XProcConfiguration, CloseableHttpClient REDIRECTION_STRATEGY)

Parameters:

config - the configuration

Throws:

java.lang.ClassNotFoundException - if any of classes necessary not found, especially if one of the classes of Apache package is not available on the class path.

DefaultFilesystem

public DefaultFilesystem(XProcConfiguration config,
                         DefaultFilesystem.REDIRECTION_STRATEGY strategy)
                  throws java.lang.ClassNotFoundException

Creates a new DefaultFilesystem with the given redirection strategy. See explanation for DefaultFileSystem(XProcConfiguration, CloseableHttpClient REDIRECTION_STRATEGY)

Parameters:

config - the configuration

strategy - the redirection strategy to use.

Throws:

java.lang.ClassNotFoundException - if any of classes necessary not found, especially if one of the classes of Apache package is not available on the class path.

DefaultFilesystem

public DefaultFilesystem(XProcConfiguration config,
                         org.apache.http.impl.client.CloseableHttpClient httpClient,
                         DefaultFilesystem.REDIRECTION_STRATEGY strategy)
                  throws java.lang.ClassNotFoundException

Creates a new DefaultFilesystem with the given XProcConfiguration. If httpClient is null, a new one is created, otherwise the provided client is used. If creation fails, a ClassNotFoundException is thrown. This will cause MorganaXProc to switch back to an alternative file system, which usally is AlternateFilesystem.

Parameters:

config - the XProcConfiguration to use.

httpClient - a CloseableHttpClient or null to create a new one.

strategy - the redirection strategy to use.

Throws:

java.lang.ClassNotFoundException - if any of classes necessary not found, especially if one of the classes of Apache package is not available on the class path.

Method Detail

clearCookieStore

protected void clearCookieStore()

Clears the cookie storage associated with the instance of this class

Overrides:

clearCookieStore in class AlternateFilesystem

httpRequest

protected XProcHttpResponse httpRequest(XProcHttpRequest request)
                                 throws java.io.IOException,
                                        XProcFilesystem.UnknownSchemeException

Performs a http request for uri schemes 'http:' and 'https'.

Overrides:

httpRequest in class AlternateFilesystem

Parameters:

request - the request to answer.

Returns:

the XProcHttpResponse for this request.

Throws:

java.io.IOException - if an IOException occurred.

XProcFilesystem.UnknownSchemeException - if the uri's scheme is unknown or not supported.
