Enclosing class:

GrpcHttp2HeadersUtils

abstract static class GrpcHttp2HeadersUtils.GrpcHttp2InboundHeaders
extends AbstractHttp2Headers

A Http2Headers implementation optimized for inbound/received headers.

Header names and values are stored in simple arrays, which makes insert run in O(1) and retrievial a O(n). Header name equality is not determined by the equals implementation of CharSequence type, but by comparing two names byte to byte.

All CharSequence input parameters and return values are required to be of type AsciiString.

namesAndValues

byte[][] namesAndValues()

Returns the header names and values as bytes. An even numbered index contains the byte[] representation of a header name (in insertion order), and the subsequent odd index number contains the corresponding header value.

The values of binary headers (with a -bin suffix), are already base64 decoded.

The array may contain several null values at the end. A null value an index means that all higher numbered indices also contain null values.

numHeaders

protected int numHeaders()

Returns the number of none-null headers in namesAndValues().
