Description
Class Summary | |
---|---|
AdjacentTextNodeMergerAdjunct | Compile an AdjacentTextNodeMerger expression to Java source code Needed only for streaming - this class is not used in XQuery |
AdjunctClassMapper | For each class of expression found on the expression tree, deliver a corresponding instance of the helper class used to generate streaming code for the expression |
ApplyImportsAdjunct | Compile an xsl:apply-imports expression/instruction to Java source code. |

AtomicSequenceConverterAdjunct | Compile a AtomicSequenceConverter expression to streaming code. |
AtomizerAdjunct | Watch factory class for an atomizer |
AverageAdjunct | Generate streaming code for the avg() function. |
BlockAdjunct | Generate streaming code for a Block, that is a sequence of expressions or instructions |
CardinalityCheckerAdjunct | Generate streaming code for a cardinality checker |
ChooseAdjunct | Streaming code to implement a conditional ("if/choose") expression |
CopyAdjunct | Compile an xsl:copy expression/instruction to streaming code. |
CopyOfAdjunct | |
CountAdjunct | Generate streaming code for the count() function. |

ElementInstrAdjunct | Generate streaming code for an xsl:element instruction |
EmptyAdjunct | Generate Java code for an empty() function call |
EmptyTextNodeRemoverAdjunct | Compile an AdjacentTextNodeMerger expression to Java source code Needed only for streaming - this class is not used in XQuery |
ExistsAdjunct | Generate streaming code for an exists() function call |
FilterExpressionAdjunct | Generate streaming code for a filter expression (when not part of a Watch). |
ForEachAdjunct | Compile an xsl:for-each instruction to streaming code. |
ForkAdjunct | Streaming code to implement an xsl:fork expression |
GeneralComparisonAdjunct | Watch factory class for a general comparison |
ItemCheckerAdjunct | Generate streaming code for an item checker |
IterateAdjunct | Compile an xsl:iterate instruction to streaming code. |
LetExpressionAdjunct | Compiles streaming code to implement a Let expression |
MinimaxAdjunct | Generate streaming code for the min() and max() functions. |
NextIterationAdjunct | Compile a xsl:next-intruction instruction to streaming code. |
NextMatchAdjunct | Compile an xsl:next-match expression/instruction to streaming code. |
ResultDocumentAdjunct | Handle an xsl:result-document expression/instruction for XSLT streaming capability. |
SimpleNodeConstructorAdjunct | Generate streaming code for an xsl:value-of, xsl:comment, xsl:processing-instruction instruction, etc |
SingletonAtomizerAdjunct | Watch factory class for a singleton atomizer |
StreamingAdjunct | This abstract class supplements an Expression with methods used at compile-time
to support streaming, by generating a Watch or Feed
that allows the expression to be evaluated in push mode. |
StringFnAdjunct | Generate Java code to implement the XPath string() function |
StringJoinAdjunct | Generate streaming code for the string-join() function. |
SumAdjunct | Generate streaming code for the avg() function. |
UnsupportedOperationAdjunct | Streaming code for an expression that does not support streaming |
WithParamAdjunct | Compile a xsl:with-param instruction to streaming code. |
This package contains classes used to support streaming. For every kind of expression that can appear in the expression tree, there is an auxiliary or adjunct class that contains the code needed to support streaming (if any).
None of these classes will be used directly by typical user applications.
The interface to these adjunct classes is defined in the abstract class
StreamingAdjunct
. The main methods
are getWatchMaker()
and getFeedMaker()
which return
a factory for respectively a Watch
and a Feed
;
a Watch is used to evaluate the expression in decomposed push mode, an event
at a time, while a Feed is used to evaluate it in composed push mode, an item
at a time.
The association between an expression class and its corresponding adjunct is
made by the AdjunctClassMapper
class.
