Class TransducedAccessor<BeanT>

java.lang.Object

com.sun.xml.bind.v2.runtime.reflect.TransducedAccessor<BeanT>

Direct Known Subclasses:

DefaultTransducedAccessor, TransducedAccessor.CompositeTransducedAccessorImpl

public abstract class TransducedAccessor<BeanT>
extends Object

Accessor and Transducer combined into one object.

This allows efficient conversions between primitive values and String without using boxing.

This abstraction only works for a single-value property.

An instance of TransducedAccessor implicitly holds a field of the BeanT that the accessors access.

TransducedAccessor

public TransducedAccessor()

Method Details

useNamespace

public boolean useNamespace()

See Also:

• Transducer.useNamespace()

declareNamespace

public void declareNamespace(BeanT o,
 XMLSerializer w)
                      throws AccessorException,
SAXException

Obtain the value of the field and declares the namespace URIs used in the value.

Throws:

AccessorException

SAXException

See Also:

• Transducer.declareNamespace(Object, XMLSerializer)

print

@Nullable
public abstract CharSequence print(@NotNull
 BeanT o)
                            throws AccessorException,
SAXException

Prints the responsible field of the given bean to the writer.

Use XMLSerializer.getInstance() to access to the namespace bindings

Returns:

if the accessor didn't yield a value, return null.

Throws:

AccessorException

SAXException

parse

public abstract void parse(BeanT o,
 CharSequence lexical)
                    throws AccessorException,
SAXException

Parses the text value into the responsible field of the given bean.

Use UnmarshallingContext.getInstance() to access to the namespace bindings

Throws:

AccessorException - if the transducer is used to parse an user bean that uses XmlValue, then this exception may occur when it tries to set the leaf value to the bean.

RuntimeException - if the lexical form is incorrect. The method may throw a RuntimeException, but it shouldn't cause the entire unmarshalling to fail.

SAXException - if the parse method found an error, the error is reported, and then the processing is aborted.

hasValue

public abstract boolean hasValue(BeanT o)
                          throws AccessorException

Checks if the field has a value.

Throws:

AccessorException

get

public static <T> TransducedAccessor<T> get(JAXBContextImpl context,
 RuntimeNonElementRef ref)

Gets the TransducedAccessor appropriately configured for the given property.

This allows the implementation to use an optimized code.

writeLeafElement

public abstract void writeLeafElement(XMLSerializer w,
 Name tagName,
 BeanT o,
 String fieldName)
                               throws SAXException,
AccessorException,
IOException,
XMLStreamException

Convenience method to write the value as a text inside an element without any attributes. Can be overridden for improved performance.

The callee assumes that there's an associated value in the field. No @xsi:type handling is expected.

Throws:

SAXException

AccessorException

IOException

XMLStreamException

writeText

public abstract void writeText(XMLSerializer w,
 BeanT o,
 String fieldName)
                        throws AccessorException,
SAXException,
IOException,
XMLStreamException

Invokes one of the XMLSerializer.text(String, String) method with the representation of data bested suited for this transduced accessor.

Throws:

AccessorException

SAXException

IOException

XMLStreamException
