public class SystemIDResolver

extends java.lang.Object

**For internal use only** This class is used to resolve relative URIs and SystemID strings into absolute URIs.

This is a generic utility for resolving URIs, other than the fact that it's declared to throw TransformerException. Please see code comments for details on how resolution is performed.

Method Summary

static java.lang.String	getAbsoluteURI(java.lang.String systemId) Take a SystemID string and try to turn it into a good absolute URI.
static java.lang.String	getAbsoluteURI(java.lang.String urlString, java.lang.String base) Take a SystemID string and try to turn it into a good absolute URI.
static java.lang.String	getAbsoluteURIFromRelative(java.lang.String localPath) Get an absolute URI from a given relative URI (local path).
static boolean	isAbsolutePath(java.lang.String systemId) Return true if the local path is an absolute path.
static boolean	isAbsoluteURI(java.lang.String systemId) Return true if the systemId denotes an absolute URI (contains the scheme part).

Method Detail

getAbsoluteURIFromRelative

public static java.lang.String getAbsoluteURIFromRelative(java.lang.String localPath)

Get an absolute URI from a given relative URI (local path).

The relative URI is a local filesystem path. The path can be absolute or relative. If it is a relative path, it is resolved relative to the system property "user.dir" if it is available; if not (i.e. in an Applet perhaps which throws SecurityException) then we just return the relative path. The space and backslash characters are also replaced to generate a good absolute URI.

Parameters:

localPath - The relative URI to resolve

Returns:

Resolved absolute URI

isAbsoluteURI

public static boolean isAbsoluteURI(java.lang.String systemId)

Return true if the systemId denotes an absolute URI (contains the scheme part).

Parameters:

systemId - The systemId string

Returns:

true if the systemId contains a scheme part

isAbsolutePath

public static boolean isAbsolutePath(java.lang.String systemId)

Return true if the local path is an absolute path.

Parameters:

systemId - The path string

Returns:

true if the path is absolute

getAbsoluteURI

public static java.lang.String getAbsoluteURI(java.lang.String systemId)

Take a SystemID string and try to turn it into a good absolute URI.

Parameters:

systemId - A URI string, which may be absolute or relative.

Returns:

The resolved absolute URI

getAbsoluteURI

public static java.lang.String getAbsoluteURI(java.lang.String urlString,
                                              java.lang.String base)
                                       throws TransformerException

Take a SystemID string and try to turn it into a good absolute URI.

Parameters:

urlString - SystemID string

base - The URI string used as the base for resolving the systemID

Returns:

The resolved absolute URI

Throws:

TransformerException - thrown if the string can't be turned into a URI.
