Overview

A sequence of bits, encoded in a byte array. Each byte in the bitmap byte array stores 8 bits of the sequence. The only exception is the last byte, which may store 8 or fewer bits. The padding defines the number of bits of the last byte to be ignored as "padding". The values of these "padding" bits are unspecified and must be ignored. To retrieve the first bit, bit 0, calculate: (bitmap[0] & 0x01) != 0. To retrieve the second bit, bit 1, calculate: (bitmap[0] & 0x02) != 0. To retrieve the third bit, bit 2, calculate: (bitmap[0] & 0x04) != 0. To retrieve the fourth bit, bit 3, calculate: (bitmap[0] & 0x08) != 0. To retrieve bit n, calculate: (bitmap[n / 8] & (0x01 << (n % 8))) != 0. The "size" of a BitSequence (the number of bits it contains) is calculated by this formula: (bitmap.length * 8) - padding.

Instance Attribute Summary

• #bitmap ⇒ String

  The bytes that encode the bit sequence.

• #padding ⇒ Fixnum

  The number of bits of the last byte in bitmap to ignore as "padding".

Instance Method Summary

• #initialize(**args) ⇒ BitSequence constructor

  A new instance of BitSequence.

• #update!(**args) ⇒ Object

  Update properties of this object.

Constructor Details

#initialize(**args) ⇒ BitSequence

Returns a new instance of BitSequence.

# File 'lib/google/apis/firestore_v1beta1/classes.rb', line 364

def initialize(**args)
   update!(**args)
end

Instance Attribute Details

#bitmap ⇒ String

The bytes that encode the bit sequence. May have a length of zero. Corresponds to the JSON property bitmap NOTE: Values are automatically base64 encoded/decoded in the client library.

Returns:

• (String)

# File 'lib/google/apis/firestore_v1beta1/classes.rb', line 355

def bitmap
  @bitmap
end

#padding ⇒ Fixnum

The number of bits of the last byte in bitmap to ignore as "padding". If the length of bitmap is zero, then this value must be 0. Otherwise, this value must be between 0 and 7, inclusive. Corresponds to the JSON property padding

Returns:

• (Fixnum)

# File 'lib/google/apis/firestore_v1beta1/classes.rb', line 362

def padding
  @padding
end
