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

Chunker.Chunk next()

Public constructors

Chunker

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

Parameters
blob InputStream

size long

chunkSize int

Public methods

hasNext

public boolean hasNext ()

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

Returns
boolean

next

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
