Properties

• property %CharCount as %Integer;
• property %CurrentDocument as EnsLib.EDI.Document;
The current Document
• property %CurrentParentSegIndex as %String;
The segment position within the current parent Document
• property %CurrentParents  [ InitialExpression = 0,MultiDimensional ];
List of enclosing parent objects ordered from outermost to immediate As EnsLib.EDI.Document
• property %LineCount as %Integer;
• property %LookaheadLine as %String;
Lookahead line left over from previous document parse
• property %LookaheadLineIsNew as %Boolean;
Flag for whether lookahead buffer has had input conversion yet
• property %NumChildren as %Integer [ MultiDimensional ];
List of counts of nested documents, ordered from outer to innermost
• property %ParentIds as %String;
List of enclosing parent objects ordered from immediate to outermost
• property %SegmentCount as %Integer;
Count of Segments tallied during parse of a TransactionSet
• property %ServiceInterface as EnsLib.EDI.ServiceInterface;
The config provider
• property %Stream as %IO.I.CharacterStream;
• property %inFraming as %String;
pre-parse of Framing setting
• property %outFraming as %String;
Framing to use on output if input framing is "Flexible"
• property ControlVersion as %String(MAXLEN=5);
This allows you to pre-set a ControlVersion to use when reading TransactionSets without an ISA or GS
• property DefCharEncoding as %String(MAXLEN=20) [ InitialExpression = "latin1" ];
Default Character Encoding to use when reading or writing X12 Documents.

Choices you can use for this setting include:

  • Native - use the default character encoding of the installed locale of the InterSystems IRIS server
  • latin1 - the ISO Latin1 8-bit encoding; this is the default
  • ISO-8859-1 - the ISO Latin1 8-bit encoding
  • UTF-8 - the Unicode 8-bit encoding
  • Unicode - the Unicode 16-bit encoding (Little-Endian)
  • UnicodeBig - the Unicode 16-bit encoding (Big-Endian)
  • Any other NLS definitions installed on this InterSystems IRIS server
  • @<ttable> - <ttable> means a raw InterSystems character translation table name. A prefix of '@' means to use the named table.
• property Done as %Boolean [ Calculated,ReadOnly ];
• property FinishBatch as %Boolean;
Should the parser skim the rest of the current batch without notifying us of any further child documents? Gets automatically cleared when the end of each top-level document is encountered
• property Framing as %String;
See your X12 Config Items for a description of accepted values.
• property ReadTimeout as %Numeric(MINVAL=-1) [ InitialExpression = 5 ];
Number of seconds to wait for each read of document data inside a started document to be available on the input stream
• property RememberFlex as %Boolean [ InitialExpression = 0 ];
Set this if you want to make an interface that is set to Framing='Flexible' continue with the Framing style it detects in the first message it receives. This can increase performance, reduce latency due to timeouts and ensure consistent behavior after initialization. However, it will also reduce the ability of the interface to interpret changing input formats in successive messages from the same source or from different sources on sequential connections.
• property SegmentTerminator as %String(MAXLEN=1,MINLEN=1);
This remembers the terminator defined in the ISA, but you can pre-set it to read TransactionSets without an ISA
• property Separators as %String(MAXLEN=3,MINLEN=3);
This remembers separators defined in the ISA, but you can pre-set it to read TransactionSets without an ISA
• property StartTimeout as %Numeric(MINVAL=-1) [ InitialExpression = 5 ];
Number of seconds to wait for the start of a document to be available on the input stream
• property TransactionSetCount as %Integer;
Count of TransactionSets in a Group
• property Whitespace as %String;
This property controls the skipping of whitespace in the data stream. Set it to a string of characters that should be considered whitespace and not part of the data

Methods

• method DoneGet() as %Boolean
This is a Get accessor method for the Done property.
• method ParseFramedIOStream(pIOStream As %IO.I.CharacterStream, Output pDoc As EnsLib.EDI.X12.Document, pInbound As %Boolean = 0, ByRef pIOLogEntry As Ens.Util.IOLog = $$$NULLOREF, pDefaultRepSep As %String = "", pDefaultCompSep As %String = "", pDefaultSegTerminator As %String = "") as %Status
Read an X12 document from the given IO Stream Returned %Status codes are not logged, except for Exceptions
• method ParseIOStream(pIOStream As %IO.I.CharacterStream, Output pDocument As EnsLib.EDI.X12.Document, ByRef pControlVersion As %String = "", pInbound As %Boolean = 0, pFramed As %Boolean = 0, pDefaultRepSep As %String = "", pDefaultCompSep As %String = "", pDefaultSegTerminator As %String = "") as %Status
Parse a complete X12 interchange document from the stream, including any nested TransactionSet documents inside it. An Interchange contains zero or more functional groups which in turn contain TransactionSets.
• method Reset()
• method ResetPosition()
• method StripWhitespace(pLine As %String) as %String
Strip off leading whitespace from the line
• classmethod applyFraming(pFraming As %String, pFlexDefault As %String = "xxf") as %String
