Return a version tag for CachedData for the current V8 version & flags.
This value is meant only for determining whether a previously generated CachedData instance is still valid; the tag has no other meaing.
Background: The data carried by CachedData may depend on the exact V8 version number or currently compiler flags. This means when persisting CachedData, the embedder must take care to not pass in data from another V8 version, or the same version with different features enabled.
The easiest way to do so is to clear the embedder's cache on any such change.
Alternatively, this tag can be stored alongside the cached data and compared when it is being used.

Returns a task which streams script data into V8, or NULL if the script cannot be streamed. The user is responsible for running the task on a background thread and deleting it. When ran, the task starts parsing the script, and it will request data from the StreamedSource as needed. When ScriptStreamingTask::Run exits, all data has been streamed and the script can be compiled (see Compile below).
This API allows to start the streaming with as little data as possible, and the remaining data (for example, the ScriptOrigin) is passed to Compile.

Compile a function for a given context. This is equivalent to running
with (obj) { return function(args) { ... } }
It is possible to specify multiple context extensions (obj in the above example).

static |
Compiles the specified script (bound to current context).
source | Script source code. |
pre_data | Pre-parsing data, as obtained by ScriptData::PreCompile() using pre_data speeds compilation if it's done multiple times. Owned by caller, no references are kept when this function returns. |
|
static |
Compiles a streamed script (bound to current context).
This can only be called after the streaming has finished (ScriptStreamingTask has been run). V8 doesn't construct the source string during streaming, so the embedder needs to pass the full source here.
|
static |
Compile an ES6 module.
This is an experimental feature.
TODO(adamk): Script is likely the wrong return value for this; should return some new Module type.
|
static |
Compiles the specified script (context-independent). Cached data as part of the source object can be optionally produced to be consumed later to speed up compilation of identical source scripts.
Note that when producing cached data, the source must point to NULL for cached data. When consuming cached data, the cached data must have been produced by the same version of V8.
