Method Detail

readObject

public abstract <T> T readObject(scala.reflect.ClassTag<T> evidence$8)

The most general-purpose method to read an object.

readKey

public <T> T readKey(scala.reflect.ClassTag<T> evidence$9)

Reads the object representing the key of a key-value pair.

readValue

public <T> T readValue(scala.reflect.ClassTag<T> evidence$10)

Reads the object representing the value of a key-value pair.

close

public abstract void close()

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface AutoCloseable

asIterator

public scala.collection.Iterator<Object> asIterator()

Read the elements of this stream through an iterator. This can only be called once, as reading each element will consume data from the input source.

Returns:

(undocumented)

asKeyValueIterator

public scala.collection.Iterator<scala.Tuple2<Object,Object>> asKeyValueIterator()

Read the elements of this stream through an iterator over key-value pairs. This can only be called once, as reading each element will consume data from the input source.

Returns:

(undocumented)
