Function Documentation

EXTERNEXI int rtEXIEncAtmAddTransition ( OSCTXT *  pctxt,

OSEXIState  fromState,
OSEXIState  toState,
const OSEXIEvent *  pEvent,
const OSEXIEventCode *  pEventCode 
)

This function adds a transition between two states.

The transition is defined by a pair of states, and event and event code.

Parameters:
pctxt Pointer to context block structure.
pAutomaton Pointer to automaton structure.
fromState The origin state for this transition.
toState The destination state for this transition.
pEvent The event on which this transition occurs.
pEventCode The event code returned after the transition.
Returns:
Zero if operation was successful; a negative status code otherwise.

EXTERNEXI OSEXIEventCode* rtEXIEncAutomatonAdvance ( OSCTXT *  pctxt,
OSEXIAutomaton *  pAutomaton,
const OSEXIEvent *  pEvent,
OSBOOL  dynamicItems 
)

This function advances the encoder automaton based on event, adding new transitions if dynamicItems is set to true and either SE(*) or AT(*) are matched instead of SE(qname) or AT(qname), respectively.

Dynamic transitions for CH are also added according to the spec.

Parameters:
pctxt Pointer to context block structure.
pAutomaton Pointer to automaton structure.
pEvent Event on which to advance the automaton.
dynamicItems Flag to add dynamic transitions to the automaton.
Returns:
The event code returned as a result of this transition.

EXTERNEXI OSEXIAutomaton* rtEXIEncGetDocAutomaton ( OSCTXT *  pctxt,
size_t  numGblElems,
const OSXMLFullQName *  gblElems 
)

This functions returns an automaton that accepts the built-in document grammar.

This grammar is not extensible, so all the event codes created are immutable.

Parameters:
pctxt Pointer to context block structure.
numGblElems Number of global elements.
gblElems Array of global element objects.
Returns:
Pointer to document automaton.

EXTERNEXI OSEXIAutomaton* rtEXIEncGetElemAutomaton ( OSCTXT *  pctxt,
OSXMLFullQName *  pqname 
)

This function returns an automaton that accepts the built-in element grammar.

The elementName is associated with the automaton.

Parameters:
pctxt Pointer to context block structure.
pqname Pointer to element QName.
Returns:
Pointer to element automaton.

EXTERNEXI OSEXIEncStringTable* rtEXIEncNewStringTable ( OSCTXT *  pctxt,
size_t  capacity 
)

This function allocates and initializes a new string table structure.

Parameters:
pctxt Pointer to context block structure.
capacity Capacity of the hash map or zero to use default.
Returns:
Allocated string table structure.

EXTERNEXI OSUINT32 rtEXIEncStringTableAdd ( OSCTXT *  pctxt,
OSEXIEncStringTable *  pstrtab,
const OSUTF8CHAR *  str 
)

This function adds a string to the given string table.

The string is not added if it already exists in the table. Its compact identifier is returned in either case.

Parameters:
pctxt Pointer to context block structure.
pstrtab Pointer to string table structure.
str Pointer to string to be added to table. A copy of the string is not made; the pointer is simply added to the table.
Returns:
Index of string in table. Note that this is an unsigned value and therefore a negative value cannot be used to signal an error condition as in other functions. In this case, the user must check the status value within the error information in the context to determine if an error occurred.

Parameters:
