Constructor Detail

OGCCapabilities

public OGCCapabilities(String namespaceURI,
                       Object docSource)

Create a new capabilities parser.

Parameters:

namespaceURI - the default namespace URI.

docSource - the XML source. May be a filename, file, stream or other type allowed by WWXML.openEventReader(Object).

Throws:

IllegalArgumentException - if the document source is null.

Method Detail

allocate

public XMLEventParser allocate(XMLEventParserContext ctx,
                               XMLEvent event)

Create a parser for a specified event.

Overrides:

allocate in class AbstractXMLEventParser

Parameters:

ctx - the current parser context.

event - the event for which the parser is created. Only the event type is used; the new parser can operate on any event of that type.

Returns:

the new parser.

createParserContext

protected XMLEventParserContext createParserContext(XMLEventReader reader)

createReader

protected XMLEventReader createReader(Object docSource)

doParseEventAttributes

protected void doParseEventAttributes(XMLEventParserContext ctx,
                                      XMLEvent event,
                                      Object... args)

Description copied from class: AbstractXMLEventParser

Parse an event's attributes.

Overrides:

doParseEventAttributes in class AbstractXMLEventParser

Parameters:

ctx - a current parser context.

event - the event to parse.

args - an optional list of arguments that may by used by subclasses.

doParseEventContent

protected void doParseEventContent(XMLEventParserContext ctx,
                                   XMLEvent event,
                                   Object... args)
                            throws XMLStreamException

Description copied from class: AbstractXMLEventParser

Parse an event's sub-elements.

Overrides:

doParseEventContent in class AbstractXMLEventParser

Parameters:

ctx - a current parser context.

event - the event to parse.

args - an optional list of arguments that may by used by subclasses.

Throws:

XMLStreamException - if an exception occurs during event-stream reading.

getCapabilityInformation

public OGCCapabilityInformation getCapabilityInformation()

Returns the document's capability information.

Returns:

the document's capability information.

getDefaultNamespaceURI

public abstract String getDefaultNamespaceURI()

Returns the default namespace URI. Must be overridden by subclasses to provide a specific URI. The default namespace is used to match XML elements found in the default namespace of the XML stream.

Returns:

the default namespace URI.

getParserContext

protected XMLEventParserContext getParserContext()

getServiceInformation

public OGCServiceInformation getServiceInformation()

Returns the document's service information.

Returns:

the document's service information.

getUpdateSequence

public String getUpdateSequence()

Returns the document's update sequence.

Returns:

the document's update sequence.

getVersion

public String getVersion()

Returns the document's version number.

Returns:

the document's version number.

isRootElementName

public abstract boolean isRootElementName(QName name)

Determines whether a specified element name is the root element name of the schema.

Parameters:

name - the name to test.

Returns:

true if the name is the schema's root element, otherwise false.

parse

public OGCCapabilities parse(Object... args)
                      throws XMLStreamException

Starts document parsing. This method initiates parsing of the XML document and returns when the full capabilities document has been parsed.

Parameters:

args - optional arguments to pass to parsers of sub-elements.

Returns:

this if parsing is successful, otherwise null.

Throws:

XMLStreamException - if an exception occurs while attempting to read the event stream.

setCapabilityInformation

setServiceInformation

protected void setServiceInformation(OGCServiceInformation serviceInformation)

setUpdateSequence

protected void setUpdateSequence(String updateSequence)

setVersion

protected void setVersion(String version)

toString

public String toString()

Overrides:

toString in class Object
