Types ¶

type BitmapIndex ¶

type BitmapIndex struct {
	// contains filtered or unexported fields
}

func NewBitmapIndex ¶

func NewBitmapIndex(b []byte) (*BitmapIndex, error)

func NewBitmapIndexFromXDR ¶

func NewBitmapIndexFromXDR(index xdr.BitmapIndex) *BitmapIndex

func (*BitmapIndex) Buffer ¶

func (i *BitmapIndex) Buffer() *bytes.Buffer

func (*BitmapIndex) DebugCompare ¶

func (i *BitmapIndex) DebugCompare(j *BitmapIndex) string

DebugCompare returns a string that compares this bitmap to another bitmap byte-by-byte in binary form as two columns.

func (*BitmapIndex) Flush ¶

func (i *BitmapIndex) Flush() []byte

Flush flushes the index data to byte slice in index format.

func (*BitmapIndex) Merge ¶

func (i *BitmapIndex) Merge(other *BitmapIndex) error

func (*BitmapIndex) NextActiveBit ¶

func (i *BitmapIndex) NextActiveBit(position uint32) (uint32, error)

NextActiveBit returns the next bit position (inclusive) where this index is active. "Inclusive" means that if it's already active at `position`, this returns `position`.

func (*BitmapIndex) SetActive ¶

func (i *BitmapIndex) SetActive(index uint32) error

func (*BitmapIndex) SetInactive ¶

func (i *BitmapIndex) SetInactive(index uint32) error

func (*BitmapIndex) Size ¶

func (i *BitmapIndex) Size() int

func (*BitmapIndex) ToXDR ¶

func (i *BitmapIndex) ToXDR() xdr.BitmapIndex

type NamedIndices ¶

type NamedIndices map[string]*BitmapIndex

type TrieIndex ¶

type TrieIndex struct {
	sync.RWMutex
	Root *trieNode `json:"root"`
}

func NewTrieIndexFromBytes ¶

func NewTrieIndexFromBytes(r io.Reader) (*TrieIndex, error)

func (*TrieIndex) Get ¶

func (index *TrieIndex) Get(key []byte) ([]byte, bool)

func (*TrieIndex) Iterate ¶

func (index *TrieIndex) Iterate(f func(key, value []byte))

func (*TrieIndex) MarshalBinary ¶

func (i *TrieIndex) MarshalBinary() ([]byte, error)

func (*TrieIndex) Merge ¶

func (i *TrieIndex) Merge(other *TrieIndex) error

TODO: For now this ignores duplicates. should it error?

func (*TrieIndex) ReadFrom ¶

func (i *TrieIndex) ReadFrom(r io.Reader) (int64, error)

func (*TrieIndex) UnmarshalBinary ¶

func (i *TrieIndex) UnmarshalBinary(bytes []byte) error

func (*TrieIndex) Upsert ¶

func (index *TrieIndex) Upsert(key, value []byte) ([]byte, bool)

func (*TrieIndex) WriteTo ¶

func (i *TrieIndex) WriteTo(w io.Writer) (int64, error)
