string
Description copied from class:ItemReturns a string representation of the value.- Specified by:
stringin classItem- Parameters:
ii- input info (can benull)- Returns:
- string value
- Throws:
QueryException- if the item cannot be atomized (caused by function or streaming items)
-
bool
Description copied from class:ItemReturns a boolean representation of the value. -
eq
Description copied from class:ItemCompares the items for equality.- Specified by:
eqin classItem- Parameters:
item- item to be comparedcoll- collation (can benull)sc- static context; required for comparing items of type xs:QName (can benull)ii- input info (can benull)- Returns:
- result of check
- Throws:
QueryException- query exception
-
sameKey
Description copied from class:ItemCompares the items for equality. -
diff
Description copied from class:ItemReturns the difference between the current and the specified item. This function is overwritten by the corresponding implementations.- Overrides:
diffin classItem- Parameters:
item- item to be comparedcoll- collation (can benull)ii- input info (can benull)- Returns:
- difference
- Throws:
QueryException- query exception
-
toJava
Description copied from class:ValueReturns a Java representation of the value. -
equals
Description copied from class:ExprThis function is e.g. called by:If.optimize(CompileContext),Switch.optimize(CompileContext),Typeswitch.optimize(CompileContext), in order to discard identical expressions.CmpR.mergeEbv(Expr, boolean, CompileContext)orCmpSR.mergeEbv(Expr, boolean, CompileContext), in order to merge expressions with identical input.CmpG.optimize(CompileContext)orCmpV.optimize(CompileContext), in order to pre-evaluate equality tests.CmpG.optimize(CompileContext)orPos.get(Expr, CmpV.OpV, InputInfo, CompileContext), in order to compare the start and end value.PathCache, in order to find identical root values at runtime.

plan
Description copied from class:ExprInfoCreates a query string.
