Method Details

getCompilationLevel

public int getCompilationLevel()
                        throws CorruptDataException

Description copied from interface: JavaLocation

Get the compilation level for this location. This is an implementation defined number indicating the level at which the current location was compiled. 0 indicates interpreted. Any positive number indicates some level of JIT compilation. Typically, higher numbers indicate more aggressive compilation strategies

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().

Specified by:

getCompilationLevel in interface JavaLocation

Returns:

the compilation level

Throws:

CorruptDataException

getFilename

public String getFilename()
                   throws DataUnavailable,
CorruptDataException

Description copied from interface: JavaLocation

Get the source file name.

Specified by:

getFilename in interface JavaLocation

Returns:

the name of the source file, if available, or throws DataUnavailable if it is not available

Description copied from interface: JavaLocation

Get the line number.

Specified by:

getLineNumber in interface JavaLocation

Returns:

the line number, if available, or throws DataUnavailable if it is not available Line numbers are counted from 1
