Evaluator

What it takes to turn an IR tree into something runnable. Upstream has two implementations, an interpreter and a bytecode compiler; this port only ever has the interpreter.

Inheritors

Interpreter

Functions

captureStackInfo

abstract fun captureStackInfo(ex: RhinoException)

Records where in the script ex was thrown.

compile

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

Compiles tree into a runnable form.

createFunctionObject

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

Wraps compiled bytecode as a callable function living in scope.

createScriptObject

abstract fun createScriptObject(bytecode: Any, staticSecurityDomain: Any?): Script

Wraps compiled bytecode as a runnable script.

getPatchedStack

abstract fun getPatchedStack(ex: RhinoException, nativeStackTrace: String): String

Rewrites a platform stack trace so it names script sources and lines.

getScriptStack

abstract fun getScriptStack(ex: RhinoException): List<String>

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

getSourcePositionFromStack

abstract 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

abstract fun setEvalScriptFlag(script: Script)

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