LLVM: llvm::OnDiskIterableChainedHashTable< Info > Class Template Reference (original) (raw)

template<typename Info>
class llvm::OnDiskIterableChainedHashTable< Info >

Provides lookup and iteration over an on disk hash table.

This needs an Info that handles reading values from the hash table's payload and computes the hash for a given key. This should provide the following interface:

class ExampleLookupInfo {

public:

typedef ExampleData data_type;

typedef ExampleInternalKey internal_key_type;

typedef ExampleKey external_key_type;

typedef uint32_t hash_value_type;

typedef uint32_t offset_type;

static bool EqualKey(internal_key_type &Key1, internal_key_type &Key2);

static const internal_key_type &GetInternalKey(external_key_type &EKey);

static std::pair<offset_type, offset_type>

ReadKeyDataLength(const unsigned char *&Buffer);

const internal_key_type &ReadKey(const unsigned char *Buffer,

offset_type KeyLen);

data_type ReadData(StringRef Key, const unsigned char *Buffer,

offset_type DataLen);

};

uint64_t ComputeHash(const FunctionSummary *FS, unsigned I)

typename base_type::hash_value_type hash_value_type

typename base_type::data_type data_type

typename base_type::internal_key_type internal_key_type

typename base_type::offset_type offset_type

typename base_type::external_key_type external_key_type

StringRef - Represent a constant reference to a string, i.e.
