precomputed
public final CharMatcher precomputed()
Description copied from class:CharMatcher
Returns achar
matcher functionally equivalent to this one, but which may be faster to query than the original; your mileage may vary. Precomputation takes time and is likely to be worthwhile only if the precomputed matcher is queried many thousands of times.This method has no effect (returns
this
) when called in GWT: it's unclear whether a precomputed matcher is faster, but it certainly consumes more memory, which doesn't seem like a worthwhile tradeoff in a browser.- Overrides:
