doParseTrieToBuilderback to summary
private static int doParseTrieToBuilder(Deque<CharSequence> stack, CharSequence encoded, int start, ImmutableMap.Builder<String, PublicSuffixType> builder)

Parses a trie node and returns the number of characters consumed.

Parameters
stack:Deque<CharSequence>

The prefixes that precede the characters represented by this node. Each entry of the stack is in reverse order.

encoded:CharSequence

The serialized trie.

start:int

An index in the encoded serialized trie to begin reading characters from.

builder:ImmutableMap.Builder<String, PublicSuffixType>

A map builder to which all entries will be added.

Returns:int

The number of characters consumed from encoded.

parseTrieback to summary
pack-priv static ImmutableMap<String, PublicSuffixType> parseTrie(CharSequence... encodedChunks)

Parses a serialized trie representation of a map of reversed public suffixes into an immutable map of public suffixes. The encoded trie string may be broken into multiple chunks to avoid the 64k limit on string literal size. In-memory strings can be much larger (2G).
