Class GoogleSecuritySafebrowsingV5RiceDeltaEncoded32Bit
The Rice-Golomb encoded data. Used for either hashes or removal indices. It is guaranteed that every hash or
index here has the same length, and this length is exactly 32 bits. Generally speaking, if we sort all the
entries lexicographically, we will find that the higher order bits tend not to change as frequently as lower
order bits. This means that if we also take the adjacent difference between entries, the higher order bits have
a high probability of being zero. This exploits this high probability of zero by essentially choosing a certain
number of bits; all bits more significant than this are likely to be zero so we use unary encoding. See the
rice_parameter
field. Historical note: the Rice-delta encoding was first used in V4 of this API. In V5, two
significant improvements were made: firstly, the Rice-delta encoding is now available with hash prefixes longer
than 4 bytes; secondly, the encoded data are now treated as big-endian so as to avoid a costly sorting step.

Syntax
public class GoogleSecuritySafebrowsingV5RiceDeltaEncoded32Bit : IDirectResponseSchema
Properties
ETag
The ETag of the item.
Declaration
public virtual string ETag { get; set; }
Property Value
Type | Description |
---|---|
string |
EncodedData
The encoded deltas that are encoded using the Golomb-Rice coder.
Declaration
[JsonProperty("encodedData")]
public virtual string EncodedData { get; set; }
Property Value
Type | Description |
---|---|
string |
EntriesCount
The number of entries that are delta encoded in the encoded data. If only a single integer was encoded, this
will be zero and the single value will be stored in first_value
.
Declaration
[JsonProperty("entriesCount")]
public virtual int? EntriesCount { get; set; }
Property Value
Type | Description |
---|---|
int? |
FirstValue
The first entry in the encoded data (hashes or indices), or, if only a single hash prefix or index was encoded, that entry's value. If the field is empty, the entry is zero.
Declaration
[JsonProperty("firstValue")]
public virtual long? FirstValue { get; set; }
Property Value
Type | Description |
---|---|
long? |
RiceParameter
The Golomb-Rice parameter. This parameter is guaranteed to be between 3 and 30, inclusive.
Declaration
[JsonProperty("riceParameter")]
public virtual int? RiceParameter { get; set; }
