Method Detail

from

public static LikeDimFilter.LikeMatcher from(String likePattern,
                                             @Nullable
                                             Character escapeChar)

matches

public boolean matches(@Nullable
                       String s)

matchesSuffixOnly

public boolean matchesSuffixOnly(Indexed<String> strings,
                                 int i)

Checks if the suffix of strings.get(i) matches the suffix of this matcher. The first prefix.length characters of s are ignored. This method is useful if you've already independently verified the prefix. This method evalutes strings.get(i) lazily to save time when it isn't necessary to actually look at the string.

predicateFactory

public DruidPredicateFactory predicateFactory(ExtractionFn extractionFn)

getPrefix

public String getPrefix()

getSuffixMatch

public LikeDimFilter.LikeMatcher.SuffixMatch getSuffixMatch()
