Method Detail

create

public static SingleRangeMatcher create(boolean invert,
                                        char lo,
                                        char hi)

getLo

public char getLo()

Returns:

inclusive lower bound of range to match.

getHi

public char getHi()

Returns:

inclusive upper bound of range to match.

estimatedCost

public int estimatedCost()

Description copied from class: CharMatcher

Conservatively estimate the equivalent number of integer comparisons of calling CharMatcher.execute(char, boolean).

Specified by:

estimatedCost in class CharMatcher

Returns:

the number of integer comparisons one call to CharMatcher.execute(char, boolean) is roughly equivalent to. Array loads are treated as two comparisons.

toString

public String toString()

Overrides:
