property ErrorHandler as %XML.XSLT.ErrorHandler [ InitialExpression = $$$NULLOREF ];
Instance of the XSLT error handler

property Filenames as %String [ Private , MultiDimensional ];
Map of XSL locations to filenames Format : ..Filenames()= Example: ..Filenames("/sda/ccd-to-sda.xsl")="C:\Healthshare\CSP\xslt\SDA\CCD-to-SDA.xsl"
Property methods: FilenamesDisplayToLogical(), FilenamesGet(), FilenamesIsValid(), FilenamesLogicalToDisplay(), FilenamesLogicalToOdbc(), FilenamesNormalize(), FilenamesSet()
property Initialized as %Boolean [ Private , InitialExpression = 0 , Transient ];
Internal flag indicating if the class needs initialization (which is automatic)
Property methods: InitializedDisplayToLogical(), InitializedGet(), InitializedIsValid(), InitializedLogicalToDisplay(), InitializedNormalize(), InitializedSet()
property InternalTransformer as %RegisteredObject [ Private , Transient ];
The transformer object used as either XSLT1 or XSLT2 transformer
Property methods: InternalTransformerGet(), InternalTransformerGetSwizzled(), InternalTransformerIsValid(), InternalTransformerNewObject(), InternalTransformerSet()
property Timestamps as %String [ Private , MultiDimensional ];
Map of filenames to last-modified timestamps (as a UTC integer value) Format : ..Timestamps()= Example: ..Timestamps("c:\healthshare\csp\xslt\sda\ccd-to-sda.xsl")=5334833340
Property methods: TimestampsDisplayToLogical(), TimestampsGet(), TimestampsIsValid(), TimestampsLogicalToDisplay(), TimestampsLogicalToOdbc(), TimestampsNormalize(), TimestampsSet()
property UseXSLT2 as %Boolean [ InitialExpression = 0 ];
The boolean to indicate whether XSLT2.0 engine is used (1 = XSLT 2.0; 0 = XSLT 1.0)
Property methods: UseXSLT2DisplayToLogical(), UseXSLT2Get(), UseXSLT2IsValid(), UseXSLT2LogicalToDisplay(), UseXSLT2Normalize(), UseXSLT2Set()
property XSLTCacheMode as %String (DISPLAYLIST = ",Always,Timestamp,Never", VALUELIST = ",A,T,N") [ InitialExpression = "T" ];
How stylesheets should be cached
  • Always - The stylesheet is loaded and compiled once
  • Timestamp - The stylesheet is loaded if file modification time is after the load time
  • Never - The stylesheet is never cached (desirable during development) NOTE: Currently, timestamps are checked only for file transforms, not XData or URLs
    Property methods: XSLTCacheModeDisplayToLogical(), XSLTCacheModeGet(), XSLTCacheModeIsValid(), XSLTCacheModeLogicalToDisplay(), XSLTCacheModeLogicalToOdbc(), XSLTCacheModeNormalize(), XSLTCacheModeSet()

    property XSLTDirectory as Ens.DataType.Directory;
    Location for file transforms (defaults to %install dir%/csp/xslt)
    Property methods: XSLTDirectoryDisplayToLogical(), XSLTDirectoryGet(), XSLTDirectoryIsValid(), XSLTDirectoryLogicalToDisplay(), XSLTDirectoryLogicalToOdbc(), XSLTDirectoryNormalize(), XSLTDirectorySet()
    property XSLTErrorHandlerClass as Ens.DataType.Class;
