property DefCharEncoding as %String;
Default Character Encoding to use when reading or writing HL7 messages.

If MSH field 18 (Character Set) is empty, this encoding will be used. Choices you can use for this setting include:

  • Native - use the default character encoding of the installed locale of the Ensemble 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 Ensemble server
  • @<ttable> - <ttable> means a raw InterSystems character translation table name. A prefix of '@' means to use the named table.
Putting ! before the encoding name will force the use of the named encoding and will ignore any value found in MSH:18.

Property methods: DefCharEncodingDisplayToLogical(), DefCharEncodingGet(), DefCharEncodingIsValid(), DefCharEncodingLogicalToDisplay(), DefCharEncodingLogicalToOdbc(), DefCharEncodingNormalize(), DefCharEncodingSet()
property Done as %Boolean [ Calculated , ReadOnly ];
Property methods: DoneDisplayToLogical(), DoneGet(), DoneIsValid(), DoneLogicalToDisplay(), DoneNormalize()

Property methods: ReadTimeoutDisplayToLogical(), ReadTimeoutGet(), ReadTimeoutIsValid(), ReadTimeoutLogicalToDisplay(), ReadTimeoutNormalize(), ReadTimeoutSet()
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 methods: RememberFlexDisplayToLogical(), RememberFlexGet(), RememberFlexIsValid(), RememberFlexLogicalToDisplay(), RememberFlexNormalize(), RememberFlexSet()
property StartTimeout as %Numeric (MINVAL = -1) [ InitialExpression = 5 ];

Methods (Including Private)

private method %OnNew(initvalue As %CacheString) as %Status
Inherited description: This callback method is invoked by the %New() method to provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:

Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.

method DoneGet() as %Boolean
method ParseFramedIOStream(pIOStream As %IO.I.CharacterStream, ByRef pMsg As EnsLib.HL7.Message, pInbound As %Boolean = 0, ByRef pIOLogEntry As Ens.Util.IOLog = $$$NULLOREF) as %Status
Read an HL7 Message from the given IO Stream Returned %Status codes are not logged, except for Exceptions
method ParseIOStream(pIOStream As %IO.I.CharacterStream, ByRef pMsg As EnsLib.HL7.Message, pInbound As %Boolean = 0, pFramed As %Boolean = 0) as %Status
Parse a complete document from the stream, including any nested documents inside it
method Reset()
method ResetPosition()
classmethod applyFraming(pFraming As %String, pFlexDefault As %String = "xxf") as %String
classmethod split(pPrev As %String, ByRef pBuf As %String, pDelims As %String) as %String
merge prev buf with current buf, return new trailing overflow buf. Split on delimiter boundary if possible return next subscript for the extra remnant
