Outcome

class Outcome(val isError: Boolean, textFn: Supplier<String>)

The result of one eval: its text plus whether it ended in error, which the MCP layer maps to tools/call isError.

text is built on first read: draining the output Capture is O(size) and that sink is unbounded, so the copy belongs on the HTTP thread already blocked on this result. The COPY only — a value is rendered eagerly, on the thread that ran the eval, because toString() is caller code and a game object's reads game state. Supplier rather than a Kotlin function type because this crosses the masking-loader seam, where only java.* has a single identity.

Constructors

Outcome

constructor(isError: Boolean, textFn: Supplier<String>)

constructor(text: String, isError: Boolean)

Constant text — nothing to defer. Also, the constructor ReplBridge calls from Java.

Properties

isError

val isError: Boolean

text

val text: String

Read once, by the one caller the result is for: every supplier behind it drains the eval's output Capture, which seals on that take and answers "" from then on.

Functions

toString

open override fun toString(): String

NOT text: that read is the one-shot drain above, so a log line or a string template that spent it would leave the caller an empty result — a silent loss, since the sink only logs a warning.
