Method Detail

item
public Bln item(QueryContext qc, InputInfo ii) throws QueryException
Description copied from class:Expr
Evaluates the expression and returns the resulting item, orEmpty.VALUE
if the expression yields an empty sequence. If this method is not implemented,Expr.value(QueryContext)
must be implemented instead.- Overrides:
item
in classParseExpr
- Parameters:
qc
- query contextii
- input info (only required bySeq
instances, which have no input info)- Returns:
- item or
Empty.VALUE
- Throws:
QueryException
- query exception
-
indexAccessible
public boolean indexAccessible(IndexInfo ii) throws QueryException
Description copied from class:Expr
Checks if an expression can be rewritten to an index access. If so, the index expression will be bound toIndexInfo.expr
. This method will be called by thePath
expression.- Overrides:
indexAccessible
in classExpr
- Parameters:
ii
- index info- Returns:
- true if an index can be used
- Throws:
QueryException
- query exception
