Chunker

public final class Chunker
extends Object

java.lang.Object
↳	com.android.tradefed.cache.remote.Chunker

Splits a blob into one or more Chunks of at most chunkSize bytes.

After blob has been fully consumed, that is until hasNext() returns false, the chunker closes the underlying data source (i.e. file) itself.

Summary

Nested classes
`class`	`Chunker.Chunk` A piece of a blob.

Public constructors
`Chunker(InputStream blob, long size, int chunkSize)`

Public methods
`boolean`	`hasNext()` Returns `true` if a subsequent call to `next()` returns a `Chunk` object.
`Chunker.Chunk`	`next()` Returns the next `Chunk` or throws a `ERROR(/NoSuchElementException)` if no data is left.

public Chunker (InputStream blob, 
                long size, 
                int chunkSize)

public boolean hasNext ()

Returns true if a subsequent call to next() returns a Chunk object.

Returns
`boolean`

public Chunker.Chunk next ()

Returns the next Chunk or throws a ERROR(/NoSuchElementException) if no data is left.

Always call hasNext() before calling this method.

Zero byte inputs are treated special. Instead of throwing a ERROR(/NoSuchElementException) on the first call to next(), a Chunk with an empty ByteString is returned.

Returns
`Chunker.Chunk`
