Member Data Documentation

XQC_Error(* XQC_DynamicContext_s::set_variable)(XQC_DynamicContext *context, const char *uri, const char *name, XQC_Sequence *value)

Sets the external variable to the value given.

The implementation takes ownership of the XQC_Sequence passed in, and is responsible for freeing it.

Parameters:

	context	The XQC_DynamicContext that this function pointer is a member of
	uri	The namespace URI of the external variable to set.
	name	The name of the external variable to set - this should be a valid lexical xs:QName. If uri is 0 and name has a prefix, that prefix is resolved using the in-scope namespace prefixes for the expression.
	value	The XQC_Sequence value for the variable, or 0 to remove the existing binding for the variable.

Return values:

	XQC_NO_ERROR
	XQC_INTERNAL_ERROR

XQC_Error(* XQC_DynamicContext_s::get_variable)(const XQC_DynamicContext *context, const char *uri, const char *name, XQC_Sequence **value)

XQC_Error(* XQC_DynamicContext_s::set_context_item)(XQC_DynamicContext *context, XQC_Sequence *value)

Sets the context item to the current item of the XQC_Sequence given.

The user remains responsible for freeing the XQC_Sequence passed as the value - the XQC_Sequence must not be freed until the XQC_DynamicContext has been freed or it's context item set to a different value.

Parameters:

	context	The XQC_DynamicContext that this function pointer is a member of
	value	The XQC_Sequence value for the context item, or 0 to remove the existing context item value.

Return values:

	XQC_NO_ERROR
	XQC_INTERNAL_ERROR
	XQC_NO_CURRENT_ITEM	if there is no current item in the value.

Examples:

xqc-context-item.c.

XQC_Error(* XQC_DynamicContext_s::get_context_item)(const XQC_DynamicContext *context, XQC_Sequence **value)

XQC_Error(* XQC_DynamicContext_s::set_implicit_timezone)(XQC_DynamicContext *context, int timezone)

The timezone given must be between -840 and +840 minutes (-14 and +14 hours).

Parameters:

timezone

The implicit timezone to set, as an offset in minutes from GMT

XQC_Error(* XQC_DynamicContext_s::get_implicit_timezone)(const XQC_DynamicContext *context, int *timezone)

XQC_Error(* XQC_DynamicContext_s::set_error_handler)(XQC_DynamicContext *context, XQC_ErrorHandler *handler)

XQC_Error(* XQC_DynamicContext_s::get_error_handler)(const XQC_DynamicContext *context, XQC_ErrorHandler **handler)

void*(* XQC_DynamicContext_s::get_interface)(const XQC_DynamicContext *context, const char *name)

Called to retrieve an implementation specific interface.

Parameters:

	context	The XQC_DynamicContext that this function pointer is a member of
	name	The name that identifies the interface to return

Returns:

A pointer to the interface, or 0 if the name is not recognized by this implementation of XQC.

void(* XQC_DynamicContext_s::free)(XQC_DynamicContext *context)

Called to free the resources associated with the XQC_DynamicContext.

Parameters:

context

The XQC_DynamicContext that this function pointer is a member of

Examples:
