public final class SourcePosition extends Object
Information about a source position for code, which includes both a line number and original bytecode address.

Fields Summary
public static final SourcePosition
NO_INFO
non-null; convenient "no information known" instance
private final com.android.dx.rop.cst.CstUtf8
sourceFile
null-ok; name of the file of origin or null if unknown
private final int
address
>= -1; the bytecode address, or -1 if that information is unknown
private final int
line
>= -1; the line number, or -1 if that information is unknown
Constructors Summary
public SourcePosition(com.android.dx.rop.cst.CstUtf8 sourceFile, int address, int line)
Constructs an instance.

param
sourceFile null-ok; name of the file of origin or null if unknown

address >= -1; original bytecode address or -1 if unknown
param
line >= -1; original line number or -1 if unknown

public intgetAddress()
Gets the original bytecode address.

return

public intgetLine()
Gets the original line number.

return
>= -1; the original line number or -1 if unknown

        return line;
public com.android.dx.rop.cst.CstUtf8getSourceFile()
Gets the source file, if known.
