drainback to summary
public byte[] drain()

Overrides org.wildfly.common.iteration.ByteIterator.drain.

Doc from org.wildfly.common.iteration.ByteIterator.drain.

Drain all the remaining bytes in this iterator.

Returns:byte[]

the remaining bytes as a single array

drainback to summary
public int drain(final byte[] dst, final int offs, final int dlen)

Overrides org.wildfly.common.iteration.ByteIterator.drain.

Doc from org.wildfly.common.iteration.ByteIterator.drain.

Drains up to len bytes from this iterator into the given dst array. An attempt is made to drain as many as len bytes, but a smaller number may be drained.

The number of bytes actually drained is returned as an integer. Unlike InputStream#read(byte[], int, int), this method never returns a negative result.

Parameters
dst:byte[]

the buffer into which the data is drained

offs:int

the start offset in array dst at which the data is written.

dlen:int

the maximum number of bytes to drain

Returns:int

the total number of bytes drained into dst, always greater or equal to 0

public ByteArrayOutputStream drainTo(final ByteArrayOutputStream stream)

Overrides org.wildfly.common.iteration.ByteIterator.drainTo.

Doc from org.wildfly.common.iteration.ByteIterator.drainTo.

Drain all the remaining bytes in this iterator to the given stream.

Parameters
stream:ByteArrayOutputStream

the stream

Returns:ByteArrayOutputStream

the same stream

Overrides org.wildfly.common.iteration.ByteIterator.drainToLatin1.

Doc from org.wildfly.common.iteration.ByteIterator.drainToLatin1.

Convenience method to directly drain a certain number of bytes to a Latin-1 string. If fewer than count bytes are available, only the available bytes will be used to construct the string.

Parameters
count:int

the maximum number of bytes to consume

Returns:String

the Latin-1 string
