Interface IntStream.Builder

All Superinterfaces:
IntConsumer
Enclosing interface:
IntStream
public static interface IntStream.Builder extends IntConsumer
A mutable builder for an IntStream.

A stream builder has a lifecycle, which starts in a building phase, during which elements can be added, and then transitions to a built phase, after which elements may not be added. The built phase begins when the build() method is called, which creates an ordered stream whose elements are the elements that were added to the stream builder, in the order they were added.

    • accept

      void accept(int t)
      Adds an element to the stream being built.
      Specified by:
      accept in interface IntConsumer
      Parameters:
      t - the input argument
      Throws:
      IllegalStateException - if the builder has already transitioned to the built state

    • add

      default IntStream.Builder add(int t)
      Adds an element to the stream being built.
      Implementation Requirements:
      The default implementation behaves as if: 
      
     accept(t)
     return this;
      Parameters:
      t - the element to add
      Returns:
      this builder
      Throws:
      IllegalStateException - if the builder has already transitioned to the built state

    • build

      IntStream build()
      Builds the stream, transitioning this builder to the built state. An IllegalStateException is thrown if there are further attempts to operate on the builder after it has entered the built state.
      Returns:
      the built stream
      Throws:
      IllegalStateException - if the builder has already transitioned to the built state
