Creates an output stream for the platform resource path and returns it. |
void |
delete(URI uri,
java.util.Map<?,?> options)
Only HTTP connections support delete. |
boolean |
exists(URI uri,
java.util.Map<?,?> options)
If a stream can be created the file exists. |

public java.io.OutputStream createOutputStream(URI uri,
java.util.Map<?,?> options)
throws java.io.IOException
This implementation does one of two things, depending on the runtime environment.
If there is an Eclipse workspace, it delegates to
WorkbenchHelper.createPlatformResourceOutputStream,
which gives the expected Eclipse behaviour.
Otherwise, the resolved URI
is delegated to createOutputStream
for recursive processing.
createOutputStream in interface URIHandlercreateOutputStream in class URIHandlerImpluri - the URI for which to create the output stream.options - a map of options to influence the kind of stream that is returned; unrecognized options are ignored and null is permitted.
java.io.IOException - if there is a problem obtaining an open output stream or a valid interpretation of the path.EcorePlugin.resolvePlatformResourcePath(String)
