P2WPKHInput class

An input for a Pay-to-Witness-Public-Key-Hash output (P2WPKH). This contains the public key that should match the hash in the associated output. It is either signed or unsigned and the addSignature method can be used to add a signature. Signature and public key data is stored in the witness data.

Methods

addSignature(InputSignature insig) → P2WPKHInput

Returns a new P2WPKHInput with the InputSignature added. Any existing signature is replaced.

override

filterSignatures(bool predicate(InputSignature insig)) → P2WPKHInput

Removes signatures that the predicate returns false for. This is used to remove invalidated signatures.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toBytes() → Uint8List

Obtains a cached Uint8List with data serialized for this object

inherited

toHex() → String

inherited

toString() → String

A string representation of this object.

inherited

write(Writer writer) → void

Override to write data into writer

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

match(RawInput raw, List<Uint8List> witness) → P2WPKHInput?

Checks if the raw input and witness data match the expected format for a P2WPKHInput, with or without a signature. If it does it returns a P2WPKHInput for the input or else it returns null.
