extends Object

Static methods from AbstractOWLParser. Mostly used by OWLOntologyDocumentSource implementations.

Method Summary

Modifier and Type	Method and Description
static Optional<InputStream>	getInputStream(IRI documentIRI, OWLOntologyLoaderConfiguration config) A convenience method that obtains an input stream from a URI.
static InputStream	wrap(InputStream delegate) Wrap an input stream to strip BOMs.
static InputStream	wrapInput(OWLOntologyDocumentSource source, OWLOntologyLoaderConfiguration configuration) Select the available input source as an input stream.
static Reader	wrapInputAsReader(OWLOntologyDocumentSource source, OWLOntologyLoaderConfiguration configuration) Call #wrapwrapInputAsReader(OWLOntologyLoaderConfiguration, String) with UTF-* as default encoding.
static Reader	wrapInputAsReader(OWLOntologyDocumentSource source, OWLOntologyLoaderConfiguration configuration, Charset encoding) Select the available input source and, if it is not already a Reader, wrap it in a Reader.

Method Detail

wrapInputAsReader

public static Reader wrapInputAsReader(OWLOntologyDocumentSource source,
                                       OWLOntologyLoaderConfiguration configuration,
                                       Charset encoding)
                                throws OWLOntologyInputSourceException

Select the available input source and, if it is not already a Reader, wrap it in a Reader. This method removes the duplication of code required for each caller to figure out if a reader or an inputstream is available. The returned Reader will be buffered.

Parameters:

source - ontology source

configuration - loader configuration to use of the reader must be built form the input IRI

encoding - character encoding if a new Reader needs to be created.

Returns:

A Reader for the input; if no Reader can be obtained, an OWLOntologyInputSourceException is thrown.

Throws:

OWLOntologyInputSourceException - if an IO related exception is thrown.

wrapInputAsReader

public static Reader wrapInputAsReader(OWLOntologyDocumentSource source,
                                       OWLOntologyLoaderConfiguration configuration)
                                throws OWLOntologyInputSourceException

Call #wrapwrapInputAsReader(OWLOntologyLoaderConfiguration, String) with UTF-* as default encoding.

Parameters:

source - ontology source

configuration - loader configuration to use of the reader must be built form the input IRI

Returns:

A Reader wrapped in an Optional; if no Reader can be obtained, the result is Optional.empty. @throws OWLOntologyInputSourceException if an IO related exception is thrown.

Throws:

OWLOntologyInputSourceException - if an IO related exception is thrown.

wrapInput

public static InputStream wrapInput(OWLOntologyDocumentSource source,
                                    OWLOntologyLoaderConfiguration configuration)
                             throws OWLOntologyInputSourceException

Select the available input source as an input stream. The input stream will be buffered.

Parameters:

source - ontology source

configuration - loader configuration to use of the reader must be built form the input IRI

Returns:

A Reader for the input; if no Reader can be obtained, an OWLOntologyInputSourceException is thrown.

Throws:

OWLOntologyInputSourceException - if an IO related exception is thrown.

getInputStream

public static Optional<InputStream> getInputStream(IRI documentIRI,
                                                   OWLOntologyLoaderConfiguration config)
                                            throws OWLOntologyInputSourceException

A convenience method that obtains an input stream from a URI. This method sets up the correct request type and wraps the input stream within a buffered input stream.

Parameters:

documentIRI - The URI from which the input stream should be returned

config - the load configuration

Returns:

The input stream obtained from the URI

Throws:

OWLOntologyInputSourceException - if there was an IOException in obtaining the input stream from the URI.

wrap

public static InputStream wrap(InputStream delegate)

Wrap an input stream to strip BOMs.

Parameters:

delegate - delegate to wrap

Returns:

wrapped input stream
