Method Detail

formatAsStackTraceElement

public static java.lang.String formatAsStackTraceElement(InjectionPoint ij,
                                                         ResourceLoader resourceLoader)

getLineNumber

public static int getLineNumber(java.lang.reflect.Member member,
                                ResourceLoader resourceLoader)

Try to get the line number associated with the given member. The reflection API does not expose such an info and so we need to analyse the bytecode. Unfortunately, it seems there is no way to get this kind of information for fields. Moreover, the LineNumberTable attribute is just optional, i.e. the compiler is not required to store this information at all. See also Java Virtual Machine Specification Implementation note: it wouldn't be appropriate to add a bytecode scanning dependency just for this functionality, therefore Apache BCEL included in Oracle JDK 1.5+ and OpenJDK 1.6+ is used. Other JVMs should not crash as we only use it if it's on the classpath and by means of reflection calls.

Parameters:

member -

resourceLoader -

Returns:

the line number or 0 if it's not possible to find it
