I will say “all of them”, whichever works for you is the best. But personally, my “best solution” is a combination of glob and iterator – This is very flexible, capable of restricting by the file types, and also easily do pagination with it.LINKS & REFERENCESScandir – PHPReaddir – PHPGlob – PHPDirectory Iterator – PHPGet Files By Extensions, Prefix, Suffix, Date – Code BoxxTHE ENDThank you for reading, and we have come to the end.

Class FileIterator Stay organized with collections Save and categorize content based on your preferences. An iterator that allows scripts to iterate over a potentially large collection of files. Fileiterators can be accessed from DriveApp or a Folder.// Log the name of every file in the user's Drive.const files = DriveApp.getFiles();while (files.hasNext()) { const file = files.next(); Logger.log(file.getName());}MethodsMethodReturn typeBrief descriptiongetContinuationToken()StringGets a token that can be used to resume this iteration at a later time.hasNext()BooleanDetermines whether calling next() will return an item.next()FileGets the next item in the collection of files or folders.Detailed documentationgetContinuationToken()Gets a token that can be used to resume this iteration at a later time. This method is usefulif processing an iterator in one execution would exceed the maximum execution time.Continuation tokens are generally valid for one week.ReturnString — a continuation token that can be used to resume this iteration with the items that remained in the iterator when the token was generatedhasNext()Determines whether calling next() will return an item.ReturnBoolean — true if next() will return an item; false if notnext()Gets the next item in the collection of files or folders.

Iterator of batches instead of a single input batch as input.Returns an iterator of output batches instead of a single output batch.The length of the entire output in the iterator should be the same as the length of the entire input.The wrapped pandas UDF takes a single Spark column as an input.You should specify the Python type hint asIterator[pandas.Series] -> Iterator[pandas.Series].This pandas UDF is useful when the UDF execution requires initializing some state, for example,loading a machine learning model file to apply inference to every input batch.The following example shows how to create a pandas UDF with iterator support.Pythonimport pandas as pdfrom typing import Iteratorfrom pyspark.sql.functions import col, pandas_udf, structpdf = pd.DataFrame([1, 2, 3], columns=["x"])df = spark.createDataFrame(pdf)# When the UDF is called with the column,# the input to the underlying function is an iterator of pd.Series.@pandas_udf("long")def plus_one(batch_iter: Iterator[pd.Series]) -> Iterator[pd.Series]: for x in batch_iter: yield x + 1df.select(plus_one(col("x"))).show()# +-----------+# |plus_one(x)|# +-----------+# | 2|# | 3|# | 4|# +-----------+# In the UDF, you can initialize some state before processing batches.# Wrap your code with try/finally or use context managers to ensure# the release of resources at the end.y_bc = spark.sparkContext.broadcast(1)@pandas_udf("long")def plus_y(batch_iter: Iterator[pd.Series]) -> Iterator[pd.Series]: y = y_bc.value # initialize states try: for x in batch_iter: yield x + y finally: pass # release resources here, if anydf.select(plus_y(col("x"))).show()# +---------+# |plus_y(x)|# +---------+# | 2|# | 3|# | 4|# +---------+Iterator of multiple Series to Iterator of Series UDF​An Iterator of multiple Series to Iterator of Series UDF has similar characteristics andrestrictions as Iterator of Series to Iterator of Series UDF. The specified function takes an iterator of batches andoutputs an iterator of batches. It is also useful when the UDF execution requires initializing somestate.The differences are:The underlying Python function takes an iterator of a tuple of pandas Series.The wrapped pandas UDF takes multiple Spark

Presentation on theme: "Interator and Iterable"— Presentation transcript: 1 Interator and IterableTwo commonly used interfaces in Java. And: for-each loop. >"> 2 >Iterator Problem: how can we access all members of a collection without knowing the structure of the collection? Solution: each collection (List, Set, Stack, ...) provides an Iterator we can use. > Iterator hasNext( ): boolean next( ): T (Object) remove(): void list ="> 3 How to Use Iterator List list =new ArrayList( ); list.add("apple"); list.add( ); // add stuff Iterator iter = list.iterator(); while ( iter.hasNext() ) { String s = iter.next( ); // do something with s } create a new Iterator for the collection. 4 Iterator Reduces DependencySuppose we have a Purse that contains Coins and a method getContents to show what is in the purse: // Suppose a purse has a collection of coins List coins = purse.getContents(); for(int k=0; k Coin c = coins.get(k); //TODO process this coin } Now the Purse must always create a List for us, even if the coins are stored is some other kind of collection, or a database. 5 Iterator Reduces Dependency (2)If getContents instead just returns an Iterator, then: // Suppose a purse has a collection of coins Iterator coins = purse.getContents(); while( coins.hasNext() ) { Coin c = coins.next(); //TODO process this coin } The purse is free to internally use any collection it wants, and does not need to create a List for us. >"> 6 >Iterable Problem: how can we get an Iterator? Forces: (1) the collection should create the iterator itself since only the collection knows its own elements. (2) every collection should provide same interface for getting an Iterator (for polymorphism). Solution: define an interface for creating iterators. Make each collection implement this interface. > Iterable iterator( ): Iterator list ="> 7 How to Use Iterable List list =new ArrayList( ); list.add( ... ); Iterator iter = list.iterator(); iterator() creates a new Iterator each time. 8 Iterable is a Factory MethodYou can eliminate direct dependency between classes by creating an interface for required behavior. the factory... the product... abstract: the factory method concrete: 9 Factory Method The Pattern Factory Interface Iterable Factory Methoditerator( ) Product Iterator Concrete Factory any collection list ="> 10 for-each loop List list =new ArrayList( ); list.add( ); // add things to list // print the list for( String s: list ) { System.out.println(s); } "for each
