# leveldb-wrapper Leveldb-wrapper is a simple library that supporing leveldb and provides an interface for key-value based database. ## KeyValueDB Interface ``` type KeyValueDB interface{ //OpenDB Open() //CloseDB Close() //Get Value by Key Get(key []byte) ([]byte, error) Put(key []byte, value []byte, sync bool) error Delete(key []byte, sync bool) error WriteBatch(KVs map[string][]byte, sync bool) error GetIteratorWithPrefix(prefix []byte) KeyValueDBIterator GetIterator(startKey []byte, endKey []byte) KeyValueDBIterator Snapshot() (map[string][]byte, error) } type KeyValueDBIterator interface { // It returns whether such pair exist. First() bool // Last moves the iterator to the last key/value pair. If the iterator // only contains one key/value pair then First and Last would moves // to the same key/value pair. // It returns whether such pair exist. Last() bool // Seek moves the iterator to the first key/value pair whose key is greater // than or equal to the given key. // It returns whether such pair exist. // // It is safe to modify the contents of the argument after Seek returns. Seek(key []byte) bool // Next moves the iterator to the next key/value pair. // It returns whether the iterator is exhausted. Next() bool // Prev moves the iterator to the previous key/value pair. // It returns whether the iterator is exhausted. Prev() bool // util.Releaser is the interface that wraps basic Release method. // When called Release will releases any resources associated with the // iterator. Release() //todo invaild when SetReleaser() // util.ReleaseSetter is the interface that wraps the basic SetReleaser // method. //SetReleaser(asd MyReleaser) // TODO: Remove this when ready. Valid() bool // Error returns any accumulated error. Exhausting all the key/value pairs // is not considered to be an error. Error() error // Key returns the key of the current key/value pair, or nil if done. // The caller should not modify the contents of the returned slice, and // its contents may change on the next call to any 'seeks method'. Key() []byte // Value returns the value of the current key/value pair, or nil if done. // The caller should not modify the contents of the returned slice, and // its contents may change on the next call to any 'seeks method'. Value() []byte } ``` ## Getting Started with leveldb-wrapper ### Installation ``` go get -u github.com/DE-labtory/leveldb-wrapper ``` ### Usage ```Go package main import ( "github.com/DE-labtory/leveldb-wrapper" "fmt" "os" ) func main(){ path := "./leveldb" dbProvider := leveldbwrapper.CreateNewDBProvider(path) defer os.RemoveAll(path) studentDB := dbProvider.GetDBHandle("Student") studentDB.Put([]byte("20164403"),[]byte("JUN"),true) name, _ := studentDB.Get([]byte("20164403")) fmt.Printf("%s",name) } ``` ## Lincese Heimdall source code files are made available under the Apache License, Version 2.0 (Apache-2.0), located in the [LICENSE](LICENSE) file.
