computeOnOrElse
inline fun <K, V, R> Map<K, V>.computeOnOrElse(key: K, defaultResult: () -> R, compute: (value: V) -> R): R
Computes the given lambda compute on value corresponding to the provided key or computes the given lambda defaultResult if the key is not present.
Return
result of compute lambda if the key is present or result of defaultResult otherwise.
Parameters
key
key which corresponding value will be used if it's present.
compute
lambda that is computed on the value corresponding to the key.
defaultResult
lambda that is computed if the key is not present.
inline fun <K, V, R> Map<K, V>.computeOnOrElse(key: K, defaultResult: R, compute: (key: K, value: V) -> R): R
Computes the given lambda compute on value corresponding to the provided key or computes the given lambda defaultResult if the key is not present.
Return
result of compute lambda if the key is present or defaultResult otherwise.
