Interface URIToFileResolve

public interface URIToFileResolve

A service interface to convert a URI into a local file. The URI is usually (always?) either a file URI or a URI pointing into the team space (also file based), e.g. "knime:/MOUNT_ID/some/path/workflow.knime".

This interface is used to resolve URIs that are stored as part of referenced meta node templates.

Method Detail

resolveToFile

File resolveToFile(URI uri)
                   throws IOException

Resolves the given URI into a local file or throws an exception if that isn't possible (e.g. because the URI does not represent a local file).

Parameters:

uri - The URI, e.g. "knime:/MOUNT_ID/some/path/workflow.knime"

Returns:

the local file represented by the URI.

Throws:

IOException - If the URI can't be resolved

resolveToLocalOrTempFile

File resolveToLocalOrTempFile(URI uri)
                              throws IOException

Resolves the given URI into a local file. If the URI does not represent a local file (e.g. a remote file on a server) it is downloaded first to a temporary directory and the the temporary copy is returned. If it represents a local file the behavior is the same as in resolveToFile(URI).

Parameters:

uri - The URI, e.g. "knime:/MOUNT_ID/some/path/workflow.knime"

Returns:

the file represented by the URI or a temporary copy of that file if it represents a remote file

Throws:

IOException - If the URI can't be resolved
