Method Detail

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

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.

len:int

the maximum number of bytes to drain

Returns:int

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

getIndexback to summary
public long getIndex()

Implements abstract org.wildfly.common.iteration.ByteIterator.getIndex.

Implements org.wildfly.common.iteration.IndexIterator.getIndex.

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

Get the current offset, in bytes.

Returns:long

the byte offset

hasNextback to summary
public boolean hasNext()

Implements abstract org.wildfly.common.iteration.ByteIterator.hasNext.

Implements org.wildfly.common.iteration.BiDirIntIterator.hasNext.

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

Determine if there are more bytes after the current byte.

Returns:boolean

true if there are more bytes, false otherwise

hasPreviousback to summary
public boolean hasPrevious()

Implements abstract org.wildfly.common.iteration.ByteIterator.hasPrevious.

Implements org.wildfly.common.iteration.BiDirIntIterator.hasPrevious.

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

Determine if there are more bytes before the current byte.

Returns:boolean

true if there are more bytes, false otherwise

public int next()

Implements abstract org.wildfly.common.iteration.ByteIterator.next.

Implements org.wildfly.common.iteration.BiDirIntIterator.next.

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

Get the next byte.

Returns:int

the next byte

Implements org.wildfly.common.iteration.BiDirIntIterator.peekPrevious.

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

Peek at the previous byte without moving backwards.

Returns:int
