+ * - mappings: A string of base64 VLQs which contain the actual mappings.
+ * - file: Optional. The generated file this source map is associated with.
+ *
+ * Here is an example source map, taken from the source map spec[0]:

+ * An IndexedSourceMapConsumer instance represents a parsed source map which

+ * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
+ * input.
+ *
+ * The first parameter is a raw source map (either as a JSON string, or already
+ * parsed to an object). According to the spec for indexed source maps, they
+ * have the following attributes:
+ *
+ * - version: Which version of the source map spec this map is following.
+ * - file: Optional. The generated file this source map is associated with.
+ * - sections: A list of section definitions.
+ *
+ * Each value under the "sections" field has two fields:
+ * - offset: The offset into the original specified at which this section
+ * begins to apply, defined as an object with a "line" and "column"
+ * field.
+ * - map: A source map definition. This source map could also be indexed,
+ * but doesn't have to be.
+ *
+ * Instead of the "map" field, it's also possible to have a "url" field
+ * specifying a URL to retrieve a source map from, but that's currently
+ * unsupported.
+ *
+ * Here's an example source map, taken from the source map spec[0], but
+ * modified to omit a section which uses the "url" field.
+ *
+ * {
+ * version : 3,
+ * file: "app.js",
+ * sections: [{
+ * offset: {line:100, column:10},
+ * map: {
+ * version : 3,
+ * file: "section.js",
+ * sources: ["foo.js", "bar.js"],
+ * names: ["src", "maps", "are", "fun"],
+ * mappings: "AAAA,E;;ABCDE;"
+ * }
+ * }],
+ * }
+ *
+ * The second parameter, if given, is a string whose value is the URL
+ * at which the source map was found. This URL is used to compute the
+ * sources array.
+ *

-// a transform stream is a readable/writable stream where you do
-// something with the data. Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored. (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation. For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes. When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up. When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer. When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks. If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk. However,
-// a pathological inflate type of transform can cause excessive buffering
-// here. For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output. In this case, you could write a very small
-// amount of input, and end up with a very large amount of output. In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform. A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

+// a transform stream is a readable/writable stream where you do
+// something with the data. Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored. (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation. For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes. When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up. When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer. When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks. If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk. However,
+// a pathological inflate type of transform can cause excessive buffering
+// here. For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output. In this case, you could write a very small
+// amount of input, and end up with a very large amount of output. In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform. A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

-/**
- * A BasicSourceMapConsumer instance represents a parsed source map which we can

- * position in the generated source.
- *
- * The first parameter is the raw source map (either as a JSON string, or
- * already parsed to an object). According to the spec, source maps have the
- * following attributes:
- *
- * - version: Which version of the source map spec this map is following.
- * - sources: An array of URLs to the original source files.
- * - names: An array of identifiers which can be referrenced by individual mappings.
- * - sourceRoot: Optional. The URL root from which all sources are relative.
- * - sourcesContent: Optional. An array of contents of the original source files.
- * - mappings: A string of base64 VLQs which contain the actual mappings.
- * - file: Optional. The generated file this source map is associated with.
- *
- * Here is an example source map, taken from the source map spec[0]:
- *
- * {
- * version : 3,
- * file: "out.js",
- * sourceRoot : "",
- * sources: ["foo.js", "bar.js"],
- * names: ["src", "maps", "are", "fun"],
- * mappings: "AA,AB;;ABCDE;"
- * }
- *
- * The second parameter, if given, is a string whose value is the URL
- * at which the source map was found. This URL is used to compute the
- * sources array.

- * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
- * input.
- *
- * The first parameter is a raw source map (either as a JSON string, or already
- * parsed to an object). According to the spec for indexed source maps, they
- * have the following attributes:
- *
- * - version: Which version of the source map spec this map is following.
- * - file: Optional. The generated file this source map is associated with.
- * - sections: A list of section definitions.
- *
- * Each value under the "sections" field has two fields:
- * - offset: The offset into the original specified at which this section
- * begins to apply, defined as an object with a "line" and "column"
- * field.
- * - map: A source map definition. This source map could also be indexed,
- * but doesn't have to be.
- *
- * Instead of the "map" field, it's also possible to have a "url" field
- * specifying a URL to retrieve a source map from, but that's currently
- * unsupported.
- *
- * Here's an example source map, taken from the source map spec[0], but
- * modified to omit a section which uses the "url" field.
- *
- * {
- * version : 3,
- * file: "app.js",
- * sections: [{
- * offset: {line:100, column:10},
- * map: {
- * version : 3,
- * file: "section.js",
- * sources: ["foo.js", "bar.js"],
- * names: ["src", "maps", "are", "fun"],
- * mappings: "AAAA,E;;ABCDE;"
- * }
- * }],
- * }
- *
- * The second parameter, if given, is a string whose value is the URL
- * at which the source map was found. This URL is used to compute the
- * sources array.
