Method Detail

getAbsoluteUri

public URI getAbsoluteUri()

Description copied from interface: IResourceDescriptor

Gets the absolute URI that identifies this resource. The URI should be unique for each resource. If there are different versions of the same resource, they should have different URIs, e.g. by including a version number in the URI. The URI is not used to access the binary data, but may be used e.g. for caching purposes.

The URI must be unique globally, i.e. also across different plugins. It is recommended to use a URI scheme that is unlikely to be used by other plugins, e.g. by including the Maven group and artifact ID.

It is an error for this method to return a URI where URI.isAbsolute() yields false.

Specified by:

getAbsoluteUri in interface IResourceDescriptor

Returns:

An absolute URI that identifies this resource.

getCharset

public Charset getCharset()

Specified by:

getCharset in interface IResourceDescriptor

Returns:

When this resource is a plain text resource: the charset or encoding of the text. Defaults to UTF_8.

open

public InputStream open()
                 throws IOException

Specified by:

open in interface IResourceDescriptor

Returns:

An input stream to the content of the resource.

Throws:

IOException - When the resource could not be opened.

toString

public String toString()

Overrides:

toString in class Object
