btree
import "github.com/fufuok/utils/generic/btree"
Package btree provides an implementation of a B-tree. A B-tree is a logarithmic search tree that maintains key-value pairs in sorted order. It is not binary because it stores more than 2 data entries per node. The branching factor for this tree is 64.
Example
package main
import (
"fmt"
g "github.com/fufuok/utils/generic"
"github.com/fufuok/utils/generic/btree"
)
func main() {
tree := btree.New[int, string](g.Less[int])
tree.Put(42, "foo")
tree.Put(-10, "bar")
tree.Put(0, "baz")
tree.Each(func(key int, val string) {
fmt.Println(key, val)
})
}
Output
-10 bar
0 baz
42 foo

type Tree
Tree implements a B-tree.
type Tree[K, V any] struct {
// contains filtered or unexported fields
}
func New
func New[K, V any](less g.LessFn[K]) *Tree[K, V]
New returns an empty B-tree.
func (*Tree[K, V]) Each
func (t *Tree[K, V]) Each(fn func(key K, val V))
Each calls 'fn' on every node in the tree in order.
func (*Tree[K, V]) Get
func (t *Tree[K, V]) Get(key K) (V, bool)
Get returns the value associated with 'key'.
func (*Tree[K, V]) Put
func (t *Tree[K, V]) Put(key K, val V)
Put associates 'key' with 'val'.
func (*Tree[K, V]) Remove
func (t *Tree[K, V]) Remove(key K)
Remove removes the value associated with 'key'.
func (*Tree[K, V]) Size
func (t *Tree[K, V]) Size() int
Size returns the number of elements in the tree.

Overview ¶
Package btree provides an implementation of a B-tree. A B-tree is a logarithmic search tree that maintains key-value pairs in sorted order. It is not binary because it stores more than 2 data entries per node. The branching factor for this tree is 64.
Example ¶
package main
import (
"fmt"
g "github.com/fufuok/utils/generic"
"github.com/fufuok/utils/generic/btree"
)
func main() {
tree := btree.New[int, string](g.Less[int])
tree.Put(42, "foo")
tree.Put(-10, "bar")
tree.Put(0, "baz")
tree.Each(func(key int, val string) {
fmt.Println(key, val)
})
}
Output: -10 bar 0 baz 42 foo
