Class: Block

provider.Block

This class is formatting the identifier of a block.

hex string and BigInt are detected as block hashes. identifier return { block_hash: hash }

decimal string and number are detected as block numbers. identifier return { block_number: number }

text string are detected as block tag. identifier return tag

null is detected as 'pending' block tag. identifier return 'pending'

Example

const result = new provider.Block(null).identifier;
// result = "pending"

Constructors

constructor

• new Block(_identifier): Block

Create a Block instance

Parameters

Name	Type	Description
_identifier	BlockIdentifier	hex string and BigInt are detected as block hashes. decimal string and number are detected as block numbers. text string are detected as block tag. null is considered as a 'pending' block tag.
