ImagePointer getAddress() throws CorruptDataException
null may be returned, particularly for methods with no bytecode or compiled sections (e.g. some native methods)
Although an offset into the method may be calculated using this pointer, caution should be exercised in attempting to map this offset to an offset within the original class file. Various transformations may have been applied to the bytecodes by the VM or other agents which may make the offset difficult to interpret.
For native methods, the address may be meaningless.
CorruptDataException
int getLineNumber() throws DataUnavailable, CorruptDataException
DataUnavailable
- if the line number data is not available for this location
CorruptDataException
java.lang.String getFilename() throws DataUnavailable, CorruptDataException
DataUnavailable
- if the source file name is unavailable in the core
CorruptDataException
int getCompilationLevel() throws CorruptDataException
For native methods, a non-zero compilation level indicates that some level of JIT compilation has been applied to the native call (e.g. a custom native call stub). To determine if the method is native, use getMethod().getModifiers().
