Method Detail

filter

public java.lang.Iterable<InputFile> filter(java.lang.Iterable<InputFile> target)

Description copied from interface: OptimizedFilePredicate

Filter provided files to keep only the ones that are valid for this predicate

Specified by:

filter in interface OptimizedFilePredicate

get

public java.lang.Iterable<InputFile> get(FileSystem.Index index)

Description copied from interface: OptimizedFilePredicate

Get all files that are valid for this predicate.

Specified by:

get in interface OptimizedFilePredicate

priority

public int priority()

Description copied from interface: OptimizedFilePredicate

For optimization. FilePredicates will be applied in priority order. For example when doing p.and(p1, p2, p3) then p1, p2 and p3 will be applied according to their priority value. Higher priority value are applied first. Assign a high priority when the predicate will likely highly reduce the set of InputFiles to filter. Also RelativePathPredicate and AbsolutePathPredicate have a high priority since they are using cache index.

Specified by:

priority in interface OptimizedFilePredicate

compareTo

public final int compareTo(OptimizedFilePredicate o)

Specified by:

compareTo in interface java.lang.Comparable<OptimizedFilePredicate>
