Method Detail

getMimeType

String getMimeType()

Returns the mime type of the input.

Returns:

the mime type of the input, may be null

getEncoding

String getEncoding()

Returns the encoding information supplied with the input.

Returns:

the encoding information supplied with the input, may be null

getSchema

String getSchema()

Returns the schema URL supplied with the input.

getValueAsBinaryStream

InputStream getValueAsBinaryStream()
                                   throws IOException

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 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

getValueAsXMLStream

XMLStreamReader getValueAsXMLStream()
                                    throws IOException,
                                           XMLStreamException

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 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

XMLStreamException
