%DeepSee.Query.node
abstract class %DeepSee.Query.node extends %Library.RegisteredObject, %XML.Adaptor
Base class for DeepSee RunTime objects.Property Inventory
Method Inventory
Parameters
parameter NAMESPACE = http://www.intersystems.com/deepsee/query;
Inherited description: NAMESPACE specifies the XML namespace to be used when projecting the
class to XML. if NAMESPACE - "", the default namespace is used for the XML schema
is used as the namespace for his class.
parameter XMLIGNOREINVALIDATTRIBUTE = 0;
Inherited description: The XMLIGNOREINVALIDATTRIBUTE parameter allows the programmer to control handling of unexpected
attributes in the XML input.
By default (XMLIGNOREINVALIDATTRIBUTE = 1), will ignore unexpected attributes.
If XMLIGNOREINVALIDATTRIBUTE is set = 0, then an unexpected attribute will be treated as an error.
parameter XMLIGNORENULL = 1;
Inherited description: XMLIGNORENULL allows the programmer to override the default XML handling
of empty strings for properties of type %String. By default (XMLIGNORENULL = 0),
empty strings in the XML input are stored as $c(0) and $c(0) is written to XML
as an empty tag. A missing tag in the XML input is always stored as "" and
"" is always output to XML as no tag.
If XMLIGNORENULL is set = 1, then both missing tags in the XML and empty strings are input as "", and both "" and $c(0) are output as empty tags (i.e. <tag></tag>).
If XMLIGNORENULL is set = "inputonly", then both missing tags in the XML and empty strings are input as "". Output of "" and $c(0) are for XMLIGNORENULL = 0: $c(0) is output as an empty tag (i.e. <tag></tag>) and "" is output as no tag.
If XMLIGNORENULL = "runtime" (runtime is not case sensitive), then the behavior of XMLIGNORENULL is determined by the format parameter of XMLExport, XMLImport and %XML.Reader.OpenFile. The default behavior for XMLIGNORENULL="runtime is the same as XMLIGNORENULL=0. Adding "ignorenull" to the format argument changes the behavior to that of XMLIGNORENULL=1. "ignorenull" shoud be separated by a comma from literal/encoded part of the format. Example values for format are "", ",ignorenull", "literal,ignorenull" and "encoded,ignorenull". Note that "inputonly" is equivalent to using ,ignorenull for XMLExport and not for %XML.Reader.
