Member Function Documentation

virtual void DynamicContext::clearDynamicContext (   )  [pure virtual]

Resets the dynamic context, as if it had never been used.

virtual DynamicContext* DynamicContext::createModuleDynamicContext (  const DynamicContext *  moduleCtx, xercesc::MemoryManager *  memMgr = xercesc::XMLPlatformUtils::fgMemoryManager )  const [pure virtual]

virtual SequenceBuilder* DynamicContext::createSequenceBuilder (   )  const [pure virtual]

Create a new SequenceBuilder, which is used to turn a stream of events into a Sequence.

virtual UpdateFactory* DynamicContext::createUpdateFactory (   )  const [pure virtual]

Creates a new UpdateFactory, used for performing updates. Caller owns the returned object, and should delete it

virtual Item::Ptr DynamicContext::getContextItem (   )  const [pure virtual]

Get the context Item.

virtual size_t DynamicContext::getContextPosition (   )  const [pure virtual]

Get the context position.

virtual size_t DynamicContext::getContextSize (   )  const [pure virtual]

Get the context size.

virtual time_t DynamicContext::getCurrentTime (   )  const [pure virtual]

Return the current time.

virtual DebugListener* DynamicContext::getDebugListener (   )  const [pure virtual]

Gets the listener for debug messages.

virtual URIResolver* DynamicContext::getDefaultURIResolver (   )  const [pure virtual]

Returns the default URIResolver.

virtual const VariableStore* DynamicContext::getGlobalVariableStore (   )  const [pure virtual]

get the variable store for globally scoped variables

virtual ATDurationOrDerived::Ptr DynamicContext::getImplicitTimezone (   )  const [pure virtual]

Return the implicit timezone for this system.

virtual const RegexGroupStore* DynamicContext::getRegexGroupStore (   )  const [pure virtual]

get the regex group store

virtual const StackFrame* DynamicContext::getStackFrame (   )  const [pure virtual]

Gets the listener for debug messages.

virtual const VariableStore* DynamicContext::getVariableStore (   )  const [pure virtual]

get the variable store

virtual Node::Ptr DynamicContext::parseDocument (  xercesc::InputSource &  srcToUse, const LocationInfo *  location = 0, const QueryPathNode *  projection = 0 )  [pure virtual]

Parse an XML document from the provided InputSource.

virtual bool DynamicContext::putDocument (  const Node::Ptr &  document, const XMLCh *  uri )  [pure virtual]

Attempts to put the document specified to the given URI by calling the registered URIResolver objects. Returns whether the operation was successful.

virtual void DynamicContext::registerURIResolver (  URIResolver *  resolver, bool  adopt )  [pure virtual]

Register a callback object for resolving URIs. Multiple URIResolver objects can be registered with the DynamicContext at the same time. The most recently added URIResolver will be called first, and if it returns false, subsequent ones will be called - ending in a call to the fallback routines. If "adopt" is false, the DynamicContext will not adopt this object, making the user responsible for making sure that the URIResolver object's lifespan matches or exceeds the life of the DynamicContext.

virtual Sequence DynamicContext::resolveCollection (  const XMLCh *  uri, const LocationInfo *  location = 0, const QueryPathNode *  projection = 0 )  [pure virtual]

Resolve the given uri (and baseUri) to a sequence of Node objects. If the uri is relative, the base uri is obtained from the context.

virtual Sequence DynamicContext::resolveDefaultCollection (  const QueryPathNode *  projection = 0  )  [pure virtual]

Resolve the default collection to a sequence of Node objects.

virtual Sequence DynamicContext::resolveDocument (  const XMLCh *  uri, const LocationInfo *  location = 0, const QueryPathNode *  projection = 0 )  [pure virtual]

Resolve the given uri (and baseUri) to an XML document. If the uri is relative, the base uri is obtained from the context.

virtual void DynamicContext::setContextItem (  const Item::Ptr &  item  )  [pure virtual]

Set the context item to item.

virtual void DynamicContext::setContextPosition (  size_t  pos  )  [pure virtual]

Set the context position.

virtual void DynamicContext::setContextSize (  size_t  size  )  [pure virtual]

Set the context size.

virtual void DynamicContext::setCurrentTime (  time_t  newTime  )  [pure virtual]

Set the current time.

virtual void DynamicContext::setDebugListener (  DebugListener *  listener  )  [pure virtual]

Set the listener for debug messages.

virtual void DynamicContext::setDefaultURIResolver (  URIResolver *  resolver, bool  adopt )  [pure virtual]

Sets the default URIResolver.

virtual void DynamicContext::setExternalVariable (  const XMLCh *  qname, const Sequence &  value )  [pure virtual]

set the value of an external global variable with the given QName

virtual void DynamicContext::setExternalVariable (  const XMLCh *  namespaceURI, const XMLCh *  name, const Sequence &  value )  [pure virtual]

set the value of an external global variable with the given uri/localname pair

virtual void DynamicContext::setGlobalVariableStore (  const VariableStore *  store  )  [pure virtual]

set the variable store for globally scoped variables

virtual void DynamicContext::setImplicitTimezone (  const ATDurationOrDerived::Ptr &  timezoneAsDuration  )  [pure virtual]

Set the implicit timezone.

virtual void DynamicContext::setRegexGroupStore (  const RegexGroupStore *  store  )  [pure virtual]

set the regex group store

virtual void DynamicContext::setStackFrame (  const StackFrame *  frame  )  [pure virtual]

Sets the current stack frame whilst debugging.

virtual void DynamicContext::setVariableStore (  const VariableStore *  store  )  [pure virtual]

set the variable store

virtual void DynamicContext::testInterrupt (   )  const [pure virtual]

Test if the query should be interrupted, and throw if so.
