preSample

The preSample hook runs just before your pattern is sampled.

Signature

null hook(Pattern pattern)

Example

pattern.on('preSample', pattern => {
  // Mutate the pattern object here
}

Notes

The preSample hook is rarely used, but it's there if you need it.

It is triggered just before the start of either:

• the Pattern.sampleOption() method
• the Pattern.sampleMeasurement() method
• the Pattern.sampleModels() method
