Constructor & Destructor Documentation

net_instaweb::Hasher::Hasher ( int  max_chars )

explicit

The passed in max_chars will be used to limit the length of Hash() and HashSizeInChars()

Member Function Documentation

GoogleString net_instaweb::Hasher::Hash

(

const StringPiece &

content

)

const

Computes a web64-encoded hash of a single string. This operation is thread-safe.

This is implemented in terms of RawHash, and honors the length limit passed in to the constructor.

int net_instaweb::Hasher::HashSizeInChars

(

)

const

Return string length of hashes produced by this hasher's Hash method.

This is implemented in terms of RawHashSizeInBytes() and the length limit passed in to the constructor.

virtual GoogleString net_instaweb::Hasher::RawHash ( const StringPiece &  content ) const

pure virtual

Computes a binary hash of the given content. The returned value is not printable as it is the direct binary encoding of the hash. This operation is thread-safe.

Implemented in net_instaweb::MockHasher, and net_instaweb::MD5Hasher.
