ReferencedComplexInput

public ReferencedComplexInput(ComplexInputDefinition definition,
                              LanguageString title,
                              LanguageString summary,

                              InputReference reference)

Creates a new ComplexInputImpl instance from a reference to a web-accessible URI.

Parameters:

definition - corresponding input definition from process description

title - optional title supplied with the input parameter, may be null

summary - optional narrative description supplied with the input parameter, may be null

format - the XML schema, format, and encoding of the complex value

reference - provides information for retrieving the input value via the web

Method Detail

getValueAsBinaryStream

public InputStream getValueAsBinaryStream()
                                   throws IOException

Description copied from interface: ComplexInput

Returns an InputStream for accessing the complex value as a raw stream of bytes (usually for binary input).

NOTE: Never use this method if the input parameter is encoded in XML -- use ComplexInput.getValueAsXMLStream() instead. Otherwise erroneous behaviour has to be expected (if the input value is given embedded in the execute request document).

Returns:

the input value as a raw stream of bytes

Throws:

IOException - if accessing the value fails

See Also:

ComplexInput.getValueAsXMLStream()

getValueAsXMLStream

public XMLStreamReader getValueAsXMLStream()
                                    throws IOException

Description copied from interface: ComplexInput

Returns an XMLStreamReader for accessing the complex value as an XML event stream.

NOTE: Never use this method if the input parameter is a binary value -- use ComplexInput.getValueAsBinaryStream() instead.

The returned stream will point at the first START_ELEMENT event of the data.

Returns:

the input value as an XML event stream, current event is START_ELEMENT (the root element of the data object)

Throws:

IOException - if accessing the value fails

getURL

public URL getURL()

Returns the URL that provides the input.

Returns:

the URL that provides the input.

toString

public String toString()

Overrides:
