Method Detail

handleNamespace

public void handleNamespace(String prefix,
                            String uri)
                     throws RDFHandlerException

Description copied from interface: RDFHandler

Handles a namespace declaration/definition. A namespace declaration associates a (short) prefix string with the namespace's URI. The prefix for default namespaces, which do not have an associated prefix, are represented as empty strings.

Specified by:

handleNamespace in interface RDFHandler

Parameters:

prefix - The prefix for the namespace, or an empty string in case of a default namespace.

uri - The URI that the prefix maps to.

Throws:

RDFHandlerException - If the RDF handler has encountered an unrecoverable error.

setWriterConfig

public RDFWriter setWriterConfig(WriterConfig config)

Description copied from interface: RDFWriter

Sets all supplied writer configuration options.

Specified by:

setWriterConfig in interface RDFWriter

Parameters:

config - a writer configuration object.

Returns:

Either a copy of this writer, if it is immutable, or this object, to allow chaining of method calls.

getWriterConfig

public WriterConfig getWriterConfig()

Description copied from interface: RDFWriter

Retrieves the current writer configuration as a single object.

Specified by:

getWriterConfig in interface RDFWriter

Returns:

a writer configuration object representing the current configuration of the writer.

getSupportedSettings

public Collection<RioSetting<?>> getSupportedSettings()

Specified by:

getSupportedSettings in interface RDFWriter

Returns:

A collection of RioSettings that are supported by this RDFWriter.

set

public <T> RDFWriter set(RioSetting<T> setting,
                         T value)

Description copied from interface: RDFWriter

Set a setting on the writer, and return this writer object to allow chaining.

Specified by:

set in interface RDFWriter

Parameters:

setting - The setting to change.

value - The value to change.

Returns:

Either a copy of this writer, if it is immutable, or this object, to allow chaining of method calls.
