Class SystemIDResolver

public final class SystemIDResolver extends Object

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.

This class is a copy of the one in org.apache.xml.utils. It exists to cut the serializers dependancy on that package. This class is not a public API, it is only public because it is used in org.apache.xml.serializer.

UNKNOWN: internal

Method Detail

getAbsoluteURI

public static String getAbsoluteURI(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 String getAbsoluteURI(String urlString, String base)
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.

getAbsoluteURIFromRelative

public static String getAbsoluteURIFromRelative(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

isAbsolutePath

public static boolean isAbsolutePath(String systemId)
Return true if the local path is an absolute path.

Parameters: systemId The path string

Returns: true if the path is absolute

isAbsoluteURI

public static boolean isAbsoluteURI(String systemId)
Return true if the systemId denotes an absolute URI .

Parameters: systemId The systemId string

Returns: true if the systemId is an an absolute URI
