Class: HashCache

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:11

A class representing a cache for transaction hash buffers. Provides methods for serialization/deserialization between Buffer, JSON, and hex formats.

Constructors

new HashCache()

new HashCache(prevoutsHashBuf, sequenceHashBuf, outputsHashBuf): HashCache

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:43

Constructs a new hash cache instance with the provided hash buffers.

Parameters

prevoutsHashBuf

Buffer

Hash buffer for prevouts

sequenceHashBuf

Buffer

Hash buffer for sequence

outputsHashBuf

Buffer

Hash buffer for outputs

Returns

HashCache

Properties

outputsHashBuf

outputsHashBuf: Buffer

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:46

Hash buffer for transaction outputs

---

prevoutsHashBuf

prevoutsHashBuf: Buffer

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:44

Hash buffer for transaction prevouts

---

sequenceHashBuf

sequenceHashBuf: Buffer

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:45

Hash buffer for transaction sequence

Methods

toBuffer()

toBuffer(): Buffer

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:51

Converts the object to a Buffer containing its JSON string representation.

Returns

Buffer

A Buffer containing the JSON string of the object.

---

toHex()

toHex(): string

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:64

Converts the object's buffer representation to a hexadecimal string.

Returns

string

Hexadecimal string representation of the buffer.

---

toJSON()

toJSON(): any

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:59

Converts the hash cache object to a JSON representation.

Returns

any

An object containing hex string representations of the hash buffers:

              - prevoutsHashBuf: Hex string of prevouts hash buffer (if exists)
              - sequenceHashBuf: Hex string of sequence hash buffer (if exists)
              - outputsHashBuf: Hex string of outputs hash buffer (if exists)

---

fromBuffer()

static fromBuffer(buf): HashCache

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:17

Creates a HashCache instance from a buffer by parsing it as JSON.

Parameters

buf

Buffer

The input buffer containing JSON data.

Returns

HashCache

A new HashCache instance created from the parsed JSON.

---

fromHex()

static fromHex(hex): HashCache

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:36

Creates a HashCache instance from a hex string.

Parameters

hex

string

The hex string to convert to a buffer.

Returns

HashCache

A HashCache instance created from the hex string buffer.

---

fromJSON()

static fromJSON(json): HashCache

Defined in: node_modules/@opcat-labs/opcat/types/hash-cache.d.cts:26

Creates a HashCache instance from a JSON object.

Parameters

json

The JSON object containing hash buffers in hex format.

outputsHashBuf?

string

Hex string for outputs hash buffer.

prevoutsHashBuf?

string

Hex string for prevouts hash buffer.

sequenceHashBuf?

string

Hex string for sequence hash buffer.

Returns

HashCache

A new HashCache instance with converted Buffer values.
