java.lang.Object net.sf.saxon.s9api.Processor
public class Processor
The Processor
class serves three purposes: it allows global Saxon configuration options to be set;
it acts as a factory for generating XQuery, XPath, and XSLT compilers; and it owns certain shared
resources such as the Saxon NamePool and compiled schemas. This is the first object that a
Saxon application should create. Once established, a Processor may be used in multiple threads.
It is possible to run more than one Saxon Processor concurrently, but only when running completely independent workloads. Nothing can be shared between Processor instances. Within a query or transformation, all source documents and schemas must be built using the same Processor, which must also be used to compile the query or stylesheet.

public Processor(boolean licensedEdition)
licensedEdition
- indicates whether the Processor requires features of Saxon that need a license
file (that is, features not available in Saxon HE (Home Edition). If true, the method will create
a Configuration appropriate to the version of the software that is running: for example, if running
Saxon-EE, it will create an EnterpriseConfiguration. The method does not at this stage check that a license
is available, and in the absence of a license, it should run successfully provided no features that
require licensing are actually used. If the argument is set to false, a plain Home Edition Configuration
is created unconditionally.public Processor(Configuration config)

public void registerExtensionFunction(ExtensionFunction function)
This interface provides only for simple extension functions that have no side-effects and no dependencies on the static or dynamic context.
function
- the implementation of the extension function.public void registerExtensionFunction(ExtensionFunctionDefinition function)
ExtensionFunctionDefinition
, using an arbitrary name and namespace.
This interface allows extension functions that have dependencies on the static or dynamic context. It also allows an extension function to declare that it has side-effects, in which case calls to the function will be optimized less aggressively than usual, although the semantics are still to some degree unpredictable.

Note that source documents specifying xml version="1.0" or "1.1" are accepted regardless of this setting.

Configuration
object that underpins this Processor. This method
provides an escape hatch to internal Saxon implementation objects that offer a finer and lower-level
degree of control than the s9api classes and methods. Some of these classes and methods may change
from release to release.
public void writeXdmValue(XdmValue value, Destination destination) throws SaxonApiException
value
- the value to be writtendestination
- the destination to which the value is to be written
SaxonApiException
- if any failure occurs, for example a serialization error
