Scala Iterator toBuffer() method with example
The toBuffer() method belongs to the concrete value members of the Class AbstractIterator. It is defined in the classes TraversableOnce and GenTraversableOnce. It employs the contents of the stated traversable or iterator to produce a new mutable buffer. It won’t end for infinite-sized collections.
Method Definition: def toBuffer: Buffer[B]
Return Type: It returns a buffer from the stated iterator’s elements.
Example:
// Scala program of toBuffer() // method // Creating object object GfG { // Main method def main(args : Array[String]) { // Declaring an iterator val iter = Iterator( 3 , 2 , 5 , 9 ) // Applying toBuffer method val result = iter.toBuffer // Displays output println(result) } } |
Output:
ArrayBuffer(3, 2, 5, 9)
Here, an Array Buffer is returned from the Iterator elements.
Example:
// Scala program of toBuffer() // method // Creating object object GfG { // Main method def main(args : Array[String]) { // Declaring an empty-iterator val iter = Iterator() // Applying toBuffer method val result = iter.toBuffer // Displays output println(result) } } |
Output:
ArrayBuffer()
Here, an empty-Array Buffer is returned from an empty Iterator.
