evaluateSampler()

function evaluateSampler<T>(sampler: Sampler<T>, ctx: SamplerContext): T;

Resolves a Sampler to a value, by calling it if it is a function, or returning it unchanged if it is a fixed value.

This can be useful when writing your own samplers that build on other samplers.

Type Parameters

T

Parameters

samplerSampler<T>

The sampler to resolve.

ctxSamplerContext

The context to pass on if the sampler is a function.

Returns

T

The sampled value.

Example

const doubled =
    (base: Sampler<number>): SamplerFn<number> =>
    (ctx) =>
        2 * evaluateSampler(base, ctx);
