|
// tools.
|
||
|
|
//
|

// For example, say we have a file like:

// message Foo {

|
|
// optional string foo = 1;
|
||
|
|

|
||
|
|
// [a,b) [ 4, 0, 2, 0, 4 ] The label (optional).
|
||
|
|
// [c,d) [ 4, 0, 2, 0, 5 ] The type (string).
|
||
|
|
// [e,f) [ 4, 0, 2, 0, 1 ] The name (foo).
|
||
|
|
// [g,h) [ 4, 0, 2, 0, 3 ] The number (1).
|
||
|
|
//
|
||
|
|
// Notes:
|
||
|
|
// - A location may refer to a repeated field itself (i.e. not to any
|
||
|
|
// particular index within it). This is used whenever a set of elements are
|
||
|
|
// logically enclosed in a single code segment. For example, an entire
|
||
|
|
// extend block (possibly containing multiple extension definitions) will
|
||
|
|
// have an outer location whose path refers to the "extensions" repeated
|
||
|
|
// field without an index.
|
||
|
|
// - Multiple locations may have the same path. This happens when a single
|
||
|
|
// logical declaration is spread out across multiple places. The most
|
||
|
|
// obvious example is the "extend" block again -- there may be multiple
|
||
|
|
// extend blocks in the same scope, each of which will have the same path.
|
||
|
|
// - A location's span is not always a subset of its parent's span. For
|
||
|
|
// example, the "extendee" of an extension declaration appears at the
|
||
|
|
// beginning of the "extend" block and is shared by all extensions within
|
||
|
|
// the block.
|
||
|
|
// - Just because a location's span is a subset of some other location's span
|
||
|
|
// does not mean that it is a descendant. For example, a "group" defines
|
||
|
|
// both a type and a field in a single declaration. Thus, the locations
|
||
|
|
// corresponding to the type and field and their components will overlap.
|
||
|
|
// - Code which tries to interpret locations should probably be designed to
|
||
|
|
// ignore those that it doesn't understand, as more types of locations could
|
||
|
|
// be recorded in the future.
