Method Detail

findElementEnd

public final boolean findElementEnd(ByteBuffer input)
                             throws EncodingException

Continue scanning input starting from offset_ to find the element end. If the end of the element which started at offset 0 is found, this returns true and getOffset() is the length of the element. Otherwise, this returns false which means you should read more into input and call again.

Parameters:

input - The input buffer. This reads starting from index 0 (not index.position()) to input.limit(). This does not update its position(). You have to pass in input each time because the buffer could be reallocated.

Returns:

true if found the element end, false if not.

Throws:

EncodingException

getOffset

public final int getOffset()

Get the current offset into the input buffer.

Returns:

The offset.

seek

public final void seek(int offset)

Set the offset into the input, used for the next read.

Parameters:

offset - The new offset.
