org.apache.commons.jexl3.internal.Debugger

All Implemented Interfaces:: JexlInfo.Detail

Direct Known Subclasses:: TemplateDebugger

public class Debugger extends ParserVisitor implements JexlInfo.Detail

Helps pinpoint the cause of problems in expressions that fail during evaluation.

It rebuilds an expression string from the tree and the start/end offsets of the cause in that string. This implies that exceptions during evaluation do always carry the node that's causing the error.

Since:: 2.0
