Rick Hillegas updated DERBY-4415:
---------------------------------
Attachment: derby-4415-01-aa-customASTprinters.diff
Attaching derby-4415-01-aa-customASTprinters. This makes it possible to plug
custom AST printers into the compiler. I am running regression tests now.
Touches the following files:
M java/engine/org/apache/derby/iapi/sql/conn/LanguageConnectionContext.java
M
java/engine/org/apache/derby/impl/sql/conn/GenericLanguageConnectionContext.java
Add accessor methods for storing a custom AST printer in the session's compiler
state.
M java/engine/org/apache/derby/iapi/sql/compile/Visitor.java
Add methods to mark the beginning and end of a printing session.
M java/engine/org/apache/derby/impl/sql/GenericStatement.java
If the custom AST printer is set, then use it after each transformation of the
AST: 1) after parsing, 2) after binding, and 3) after optimization.
M
java/engine/org/apache/derby/impl/sql/compile/HasVariantValueNodeVisitor.java
M
java/engine/org/apache/derby/impl/sql/compile/VerifyAggregateExpressionsVisitor.java
M
java/engine/org/apache/derby/impl/sql/compile/ReplaceAggregatesWithCRVisitor.java
M
java/engine/org/apache/derby/impl/sql/compile/HasCorrelatedCRsVisitor.java
M java/engine/org/apache/derby/impl/sql/compile/VTIDeferModPolicy.java
M java/engine/org/apache/derby/impl/sql/compile/CollectNodesVisitor.java
M
java/engine/org/apache/derby/impl/sql/compile/SubstituteExpressionVisitor.java
M java/engine/org/apache/derby/impl/sql/compile/HasNodeVisitor.java

M
java/engine/org/apache/derby/impl/sql/compile/ReferencedTablesVisitor.java
M java/engine/org/apache/derby/impl/sql/compile/RemapCRsVisitor.java
Add vacuous implementations of the new begin() and end() brackets to our
existing Visitors.

> It would be nice to be able to tell the compiler to use user-written
> formatters for pretty-printing Derby's abstract syntax trees. For instance,
> it would be nice to be able to plug in the AST printers attached to
> DERBY-791, including the Eclipse-based tree grapher written by Kay Röpke.
