Methods

extractStep

extractStep(
    input: Uint8Array,
    cursor: number,
    endCursor: number,
): undefined | [Uint8Array, number]
Parse a step hex value out to a binary value with the number of bits.
Parameters
- input: Uint8Array
  The input buffer to match against.
- cursor: number
  The cursor to test the match against.
- endCursor: number
  The end point to look at in the buffer.
Returns undefined | [Uint8Array, number]
The extracted value or undefined.

get

get(value: number, state: number): number
Get the value of a given state for a given value.

Useful for using this for mappings. Will cause an exception if out of bounds.
Parameters
- value: number
  The byte value to lookup.
- state: number
  The state to get the value for.
Returns number
Inherited from default.get

prefixed

prefixed(
    input: Uint8Array,
    cursor: number,
    endCursor: number,

Match hex data, with a C style prefix of 0x or 0X.
Parameters
- input: Uint8Array
  The input buffer to match against.
- cursor: number
  The cursor to test the match against.
- endCursor: number
  The end point to look at in the buffer.
Returns undefined | number
The end of the match or undefined if none found.

step

step(input: Uint8Array, cursor: number, endCursor: number): undefined | number
Match hex data, with a STEP style
Parameters
- input: Uint8Array
  The input buffer to match against.
- cursor: number
  The cursor to test the match against.
- endCursor: number
  The end point to look at in the buffer.
Returns undefined | number
The end of the match or undefined if none found.

unprefixed

unprefixed(
    input: Uint8Array,
    cursor: number,
    endCursor: number,
): undefined | number
Match unprefixed hex data.
Parameters
- input: Uint8Array
  The input buffer to match against.
