org.apache.cxf.databinding
Interface DataReader<T>

Type Parameters:

T - The type of the source. Each data binding defines the set of source types that it supports.

All Known Implementing Classes:

DataReaderImpl, DataReaderImpl, DataReaderImpl, ElementDataReader, JibxDataReader, NodeDataReader, StaxDataBinding.XMLStreamDataReader, XMLStreamDataReader, XMLStreamDataReader

public interface DataReader<T>

The 'read' side of the data binding abstraction of CXF. A DataReader<T> reads objects from a source of type T.

FAULT

static final String FAULT

ENDPOINT

static final String ENDPOINT

setSchema

void setSchema(Schema s)

Supply a schema to validate the input. Bindings silently ignore this parameter if they do not support schema validation, or the particular form of validation implied by a particular form of Schema.

Parameters:

s -

setAttachments

void setAttachments(Collection<Attachment> attachments)

Attach a collection of attachments to a binding. This permits a binding to process the contents of one or more attachments as part of reading from this reader.

Parameters:

attachments - attachments.

setProperty

void setProperty(String prop,
                 Object value)

Set an arbitrary property on the reader. FAULT and ENDPOINT specify two common properties: the Fault object being read and the Endpoint.

Parameters:

prop - Name of the property.

value - Value of the property.

read

Object read(T input)

Read an object from the input.

Parameters:

input - input source object.

Returns:

item read.

read

Object read(MessagePartInfo part,
            T input)

Read an object from the input, applying additional conventions based on the WSDL message part.

Parameters:

part - The message part for this item. If null, this API is equivalent to read(Object).

input - input source object.

Returns:

item read.

read

Object read(QName elementQName,
            T input,
            Class<?> type)

Read an object from the input. In the current version of CXF, not all binding support this API, and those that do ignore the element QName parameter.

Parameters:

elementQName - expected element. Generally ignored.

input - input source object.

type - the type of object required/requested. This is generally used when the caller wants to receive a raw source object and avoid any binding processing. For example, passing javax.xml.transform.Source. The bindings do not necessarily throw if they cannot provide an object of the requested type, and will apply their normal mapping processing, instead.

Returns:

item read.
