Method Detail

fromDirectory

@NonNull
public static java.util.Set<RelativeFile> fromDirectory(@NonNull
                                                                 java.io.File directory)

Loads all files in a directory recursively.

Parameters:

directory - the directory, must exist and be a readable directory

Returns:

all files in the directory, sub-directories included

fromDirectory

@NonNull
public static java.util.Set<RelativeFile> fromDirectory(@NonNull
                                                                 java.io.File directory,
                                                                 @NonNull

Loads all files in a directory recursively, filtering the results with a predicate. Filtering is only done at the end so, even if a directory is excluded from the filter, its files will be included if they are accepted by the filter.

Parameters:

directory - the directory, must exist and be a readable directory

filter - a predicate to filter which files should be included in the result; only files to whom the filter application results in true are included in the result

Returns:

all files in the directory, sub-directories included

fromPathPredicate

@NonNull
public static java.util.function.Predicate<RelativeFile> fromPathPredicate(@NonNull
                                                                                    java.util.function.Predicate<java.lang.String> predicate)

Constructs a predicate over relative files from a predicate over paths, applying it to the normalized relative path contained in the relative file.

Parameters:

predicate - the file predicate

Returns:

the relative file predicate built upon predicate

fromZip

@NonNull
public static java.util.Set<RelativeFile> fromZip(@NonNull
                                                           com.android.builder.files.ZipCentralDirectory zip)
                                                    throws java.io.IOException

Reads a zip file and adds all files in the file in a new relative set.

Parameters:

zip - the zip file to read, must be a valid, existing zip file

Returns:

the file set

Throws:

java.io.IOException - failed to read the zip file
