-
analyze
public void analyze(AnalyzeContextInfo contextInfo)
throws XPathException
- Description copied from interface:
Expression
- Statically analyze the expression and its subexpressions.
During the static analysis phase, the query engine can detect
unknown variables and some type errors.
- Specified by:
analyze
in interface Expression
- Overrides:
analyze
in class Function
- Throws:
XPathException
eval
