BloombergLP::bslh::hashAppend

Combine the specified input into the state of the specified hashAlg.

Synopsis

Declared in <bslh_hash.h>

template<
    class HASH_ALGORITHM,
    class TYPE>
void
hashAppend(
    HASH_ALGORITHM& hashAlg,
    TYPE input)
requires bsl::is_same<TYPE, bool>::value;

Description

Passes the specified input into the specified hashAlg to be combined into the internal state of the algorithm which is used to produce the resulting hash value. Note that the enable_if meta‐function is used to enable this hashAppend function for only bool, because bool`s can have multiple `true representations and need to be normalized before they can be hashed as a continuous sequence of bytes.

Parameters

Name

Description

hashAlg

hashing algorithm to update

input

value to incorporate into the hash
