Interpreter

The interpreter: the one Evaluator this engine has. It runs the icode CodeGenerator emits, one call frame per script function, with the frames linked so an exception or a yield can unwind them without touching the host stack.

Upstream keeps a table of one object per opcode; this port dispatches with a when over the same opcodes, which is what older Rhino did. The cases are the same code (D-30).

Continuations (NativeContinuation, captureContinuation) are not ported (D-31).

Functions

captureStackInfo

open override fun captureStackInfo(ex: RhinoException)

Records where in the script ex was thrown.

compile

open override fun compile(compilerEnv: CompilerEnvirons, tree: ScriptNode, rawSource: String, returnFunction: Boolean): Any

Compiles tree into a runnable form.

createFunctionObject

open override fun createFunctionObject(cx: Context, scope: Scriptable, bytecode: Any, staticSecurityDomain: Any?): Function

Wraps compiled bytecode as a callable function living in scope.

createScriptObject

open override fun createScriptObject(bytecode: Any, staticSecurityDomain: Any?): Script

Wraps compiled bytecode as a runnable script.

getPatchedStack

open override fun getPatchedStack(ex: RhinoException, nativeStackTrace: String): String

There is no host stack trace to patch off the JVM, so the trace comes back as given.

getScriptStack

open override fun getScriptStack(ex: RhinoException): List<String>

The script-level stack for ex, one entry per frame.

getSourcePositionFromStack

open override fun getSourcePositionFromStack(cx: Context, linep: IntArray): String?

Reads the current source position off the interpreter stack. The line number is written to linep[0]; the return value is the source name.

setEvalScriptFlag

open override fun setEvalScriptFlag(script: Script)

Marks script as having come from eval or the Function constructor.
