getXmlWriter

public IXMLWriter getXmlWriter()
Get the writer being used for output.

Specified by:
getXmlWriter in interface IMarshallingContext

Set the writer being used for output.

Specified by:
setXmlWriter in interface IMarshallingContext
Parameters:
xwrite - XML writer used for output

getIndent

public int getIndent()
Get current nesting indent spaces. This returns the number of spaces used to show indenting, if used.

Specified by:
getIndent in interface IMarshallingContext
Returns:
number of spaces indented per level, or negative if indentation disabled

setIndent

public void setIndent(int count)
Set nesting indent spaces. This is advisory only, and implementations of this interface are free to ignore it. The intent is to indicate that the generated output should use indenting to illustrate element nesting.

Specified by:
setIndent in interface IMarshallingContext
Parameters:
count - number of spaces to indent per level, or disable indentation if negative

setIndent

public void setIndent(int count,
                      java.lang.String newline,
                      char indent)
Set nesting indentation. This is advisory only, and implementations of this interface are free to ignore it. The intent is to indicate that the generated output should use indenting to illustrate element nesting.

Specified by:
setIndent in interface IMarshallingContext
Parameters:
count - number of character to indent per level, or disable indentation if negative (zero means new line only)
newline - sequence of characters used for a line ending (null means use the single character '\n')
indent - whitespace character used for indentation

setFromContext

public void setFromContext(MarshallingContext parent)
                    throws java.io.IOException
Initializes the context to use the same marshalled text destination and parameters as another marshalling context. This method is designed for use when an initial context needs to create and invoke a secondary context (generally from a different binding) in the course of an marshalling operation. Note that once the secondary context has been used it's generally necessary to do a XMLWriterBase.flush() operation on the writer used by the that context before resuming output on the parent.

Parameters:
parent - context supplying target for marshalled document text
Throws:
java.io.IOException - on error writing output

reset

public void reset()
Reset to initial state for reuse. The context is serially reusable, as long as this method is called to clear any retained state information between uses. It is automatically called when output is set.

Specified by:
reset in interface IMarshallingContext

getFactory

public IBindingFactory getFactory()
Return the binding factory used to create this unmarshaller.

Returns:
binding factory

getNamespaces

public java.lang.String[] getNamespaces()
Get namespace URIs for mapping. This gets the full ordered array of namespaces known in the binding used for this marshalling, where the index number of each namespace URI is the namespace index used to lookup the prefix when marshalling a name in that namespace. The returned array must not be modified.

Returns:
array of namespaces

                          throws JiBXException
Find the marshaller for a particular class index in the current context.

Specified by:
getMarshaller in interface IMarshallingContext
Parameters:
mapname - marshaller mapping name (generally the class name to be handled, or abstract mapping type name)
Returns:
marshalling handler for class
Throws:
JiBXException - on any error (possibly wrapping other exception)

marshalDocument

public void marshalDocument(java.lang.Object root)
                     throws JiBXException
Marshal document from root object without XML declaration. This can only be validly called immediately following one of the set output methods; otherwise the output document will be corrupt. The effect of this method is the same as the sequence of a call to marshal the root object using this context followed by a call to endDocument().

Specified by:
marshalDocument in interface IMarshallingContext
Parameters:
root - object at root of structure to be marshalled, which must have a top-level mapping in the binding
Throws:
JiBXException - on any error (possibly wrapping other exception)

marshalDocument

public void marshalDocument(java.lang.Object root,
                            java.lang.String enc,
                            java.lang.Boolean alone)
                     throws JiBXException
Marshal document from root object. This can only be validly called immediately following one of the set output methods; otherwise the output document will be corrupt. The effect of this method is the same as the sequence of a call to startDocument(java.lang.String, java.lang.Boolean), a call to marshal the root object using this context, and finally a call to endDocument().

Specified by:
marshalDocument in interface IMarshallingContext
Parameters:
root - object at root of structure to be marshalled, which must have a top-level mapping in the binding
enc - document encoding, null if not specified
alone - standalone document flag, null if not specified
Throws:
JiBXException - on any error (possibly wrapping other exception)

marshalDocument

public void marshalDocument(java.lang.Object root,
                            java.lang.String enc,
                            java.lang.Boolean alone,
                            java.io.OutputStream outs)
                     throws JiBXException
Marshal document from root object to output stream with encoding. The effect of this method is the same as the sequence of a call to startDocument(java.lang.String, java.lang.Boolean), a call to marshal the root object using this context, and finally a call to endDocument().

Specified by:
marshalDocument in interface IMarshallingContext
Parameters:
root - object at root of structure to be marshalled, which must have a top-level mapping in the binding
enc - document encoding, null if not specified
alone - standalone document flag, null if not specified
outs - stream for document data output
Throws:
JiBXException - on any error (possibly wrapping other exception)

marshalDocument

public void marshalDocument(java.lang.Object root,
                            java.lang.String enc,
                            java.lang.Boolean alone,
                            java.io.Writer outw)
                     throws JiBXException
Marshal document from root object to writer. The effect of this method is the same as the sequence of a call to startDocument(java.lang.String, java.lang.Boolean), a call to marshal the root object using this context, and finally a call to endDocument().

Specified by:
marshalDocument in interface IMarshallingContext
Parameters:
root - object at root of structure to be marshalled, which must have a top-level mapping in the binding
enc - document encoding, null if not specified
alone - standalone document flag, null if not specified
outw - writer for document data output
Throws:
JiBXException - on any error (possibly wrapping other exception)

pushNamespaces

public void pushNamespaces(java.lang.String factname)
Use namespace indexes from a separate binding, as identified by that binding's factory class name. The target binding must be a precompiled base binding of the binding used to create this marshalling context, either directly or by way of some other precompiled base binding(s).

Specified by:
pushNamespaces in interface IMarshallingContext
Parameters:
factname - binding factory class name for binding defining namespaces

popNamespaces

public void popNamespaces()
End use of namespace indexes from a separate binding. This will undo the effect of the most-recent call to pushNamespaces(String), restoring whatever namespace usage was in effect prior to that call.

Specified by:
popNamespaces in interface IMarshallingContext

getIdMap

public java.util.HashMap getIdMap()
Get shared ID map. The ID map returned is not used directly by the marshalling code, but is provided to support user extensions.

Returns:
ID map

setUserContext

public void setUserContext(java.lang.Object obj)
Set a user context object. This context object is not used directly by JiBX, but can be accessed by all types of user extension methods. The context object is automatically cleared by the reset() method, so to make use of this you need to first call the appropriate version of the setOutput() method, then this method, and finally one of the marshalDocument methods which uses the previously-set output (not the ones which take a stream or writer as parameter, since they call setOutput() themselves).

Specified by:
setUserContext in interface IMarshallingContext
Parameters:
obj - user context object, or null if clearing existing context object
See Also:
getUserContext()

getUserContext

public java.lang.Object getUserContext()
Get the user context object.

Specified by:
getUserContext in interface IMarshallingContext
Returns:
user context object, or null if no context object set
See Also:
setUserContext(Object)

pushObject

public void pushObject(java.lang.Object obj)
Push created object to marshalling stack. This must be called before beginning the marshalling of the object. It is only called for objects with structure, not for those converted directly to and from text.

Specified by:
pushObject in interface IMarshallingContext
Parameters:
obj - object being marshalled

popObject

public void popObject()
               throws JiBXException
Pop marshalled object from stack.

Specified by:
popObject in interface IMarshallingContext
Throws:
JiBXException - if no object on stack

getStackDepth

public int getStackDepth()
Get current marshalling object stack depth. This allows tracking nested calls to marshal one object while in the process of marshalling another object. The bottom item on the stack is always the root object being marshalled.

Specified by:
getStackDepth in interface IMarshallingContext
Returns:
number of objects in marshalling stack

getStackObject

public java.lang.Object getStackObject(int depth)
Get object from marshalling stack. This stack allows tracking nested calls to marshal one object while in the process of marshalling another object. The bottom item on the stack is always the root object being marshalled.

Specified by:
getStackObject in interface IMarshallingContext
Parameters:
depth - object depth in stack to be retrieved (must be in the range of zero to the current depth minus one).
Returns:
object from marshalling stack

getStackTop

public java.lang.Object getStackTop()
Get top object on marshalling stack. This is safe to call even when no objects are on the stack.

Specified by:
getStackTop in interface IMarshallingContext
Returns:
object from marshalling stack, or null if none
