Class SplitPositionBufProcessor

java.lang.Object

com.couchbase.client.core.endpoint.util.AbstractStringAwareBufProcessor

com.couchbase.client.core.endpoint.util.SplitPositionBufProcessor

All Implemented Interfaces:

ByteBufProcessor

public class SplitPositionBufProcessor
extends AbstractStringAwareBufProcessor
implements ByteBufProcessor

A ByteBufProcessor to find the position of a single character usable as a split pivot. Applying this to a buffer will output the position of the closing of the section, relative to that buffer’s readerIndex, or -1 if the end of the section couldn’t be found.

Note that this processor is typically used to find split positions in a JSON array inside a streaming JSON response (in which case the constructor variant that detects JSON strings should be used).

It is invoked on a ByteBuf by calling ByteBuf.forEachByte(ByteBufProcessor) methods.
