class webpack.sources.PrefixSource extends Source
new PrefixSource(prefix, source): PrefixSource

Returns:PrefixSource

clearCache(options?, visited?): void
Attributes
options:ClearCacheOptions
visited:WeakSet<Source>
Returns:void

Release cached data held by this source. clearCache is a memory hint: it never affects correctness or output, only how expensive the next read is. Subclasses override; the base is a no-op so every Source supports the call. Composite sources always recurse into wrapped sources. When the same child is reachable via several parents (e.g. modules shared across webpack chunks), pass a shared visited WeakSet so each subtree is walked at most once. Not safe to call concurrently with source/map/sourceAndMap/ streamChunks/updateHash on the same instance.
