Enumeration Type Documentation

enum OSEXIEventType

A structure representing an EXI event.

An event is a pair of an event type and a possibly null qname. Only SE and AT events accept a qname parameter. For all other events, the static constants defined in this class must be used. Note that SE(*) and AT(*) are represented by SE and AT, respectively.

Function Documentation

EXTERNEXI void rtEXIEventDeepCopy ( OSCTXT *  pctxt,
OSEXIEvent *  pdest,
const OSEXIEvent *  psrc 
)

This function makes a deep copy of the given Event including the strings inside.

Parameters:
pctxt Pointer to a context structure.
pdest Pointer to Event to receive copied data.
psrc Pointer to Event to be copied.

EXTERNEXI void rtEXIEventFreeMem ( OSCTXT *  pctxt,
OSEXIEvent *  pEvent,
OSBOOL  dynamic 
)

This function frees all memory within an Event structure.

Parameters:
pctxt Pointer to a context structure.
pEvent Pointer to Event in which memory will be freed.
dynamic Boolean indicating if pEvent is dynamic. If true, the memory for pEvent is freed.

EXTERNEXI OSUINT32 rtEXIEventHash ( const OSEXIEvent *  pEvent  ) 

This function computes a hash code for an event structure.

Parameters:
pEvent Pointer to event structure.
Returns:
Computed hash code.

EXTERNEXI void rtEXIEventInit ( OSCTXT *  pctxt,
OSEXIEvent *  pEvent,
OSEXIEventType  type,
const OSXMLFullQName *  qname 
)

This function initializes an event structure.

Parameters:
pctxt Pointer to a context block structure.
pEvent Pointer to event structure.
type Type of the event.
qname QName associated with the event (possibly NULL).

EXTERNEXI void rtEXIEventPrint ( const OSEXIEvent *  pEvent  ) 

This function prints information on the given event to stdout.

Parameters:
pEvent Pointer to event structure.

EXTERNEXI OSBOOL rtEXIEventsEqual ( const OSEXIEvent *  pEvent1,
const OSEXIEvent *  pEvent2 
)

This function tests if two event structures are equal.

Parameters:
pEvent1 Pointer to event structure.
pEvent2 Pointer to event structure.
Returns:
True if events are equal.

EXTERNEXI OSUTF8CHAR* rtEXIEventToString ( OSCTXT *  pctxt,
const OSEXIEvent *  pEvent 
)

This function returns the full textual description for the given event.

This includes the type (for example, "SD", "SE", etc.) and, if SE or AT, the local name or '*'.

Parameters:
pctxt Pointer to a context structure.
pEvent Pointer to Event structure.
Returns:
Text corresponding to the type.

EXTERNEXI const char* rtEXIEventTypeToString ( OSEXIEventType  type  ) 

This function returns the textual name for the given event type (for example, "SD", "SE", etc.

). The code is returned as string literal text.

Parameters:
type Enumerated event type.
Returns:
Text corresponding to the type.

EXTERNEXI const OSEXIEvent* rtEXIGetBaseEvent ( const OSEXIEvent *  pEvent  ) 

This function gets the base event corresponding to a given event.

For SE or AT events, this is SE(*) or AT(*) respectively. For all other events, it is the event itself.

Parameters:
pEvent Pointer to event structure.
Returns:
Pointer to base event.

EXTERNEXI OSEXIEvent* rtEXINewEvent ( OSCTXT *  pctxt,
OSEXIEventType  type,
const OSXMLFullQName *  qname 
)

This function allocates a new event structure and initializes it.

Parameters:
pctxt Pointer to a context block structure.
type Type of the event.
qname QName associated with the event (possibly NULL).
Returns:
Pointer to allocated event structure or NULL if no dynamic memory available.

EXTERNEXI OSEXIEvent* rtEXINewEventDeepCopy ( OSCTXT *  pctxt,
const OSEXIEvent *  pEvent 
)

This function creates a deep copy of the given event record.

Memory for the record is allocated using rtxMemAlloc. The record should be freed using rtEXIEventFreeMem.

Parameters:
pctxt Pointer to a context block structure.
pEvent Pointer to event record to be copied.
Returns:
Pointer to allocated event structure or NULL if no dynamic memory available.
