HitFlags¶

class vallenae.io.HitFlags(value)[source]¶

Hit record flags.

Methods

`conjugate`	Returns self, the complex conjugate of any int.
`bit_length`()	Number of bits necessary to represent self in binary.
`bit_count`()	Number of ones in the binary representation of the absolute value of self.
`to_bytes`([length, byteorder, signed])	Return an array of bytes representing an integer.
`from_bytes`(bytes[, byteorder, signed])	Return the integer represented by the given array of bytes.
`as_integer_ratio`()	Return integer ratio.
`__init__`(args, *kwds)

Attributes

`real`	the real part of a complex number
`imag`	the imaginary part of a complex number
`numerator`	the numerator of a rational number in lowest terms
`denominator`	the denominator of a rational number in lowest terms
`TIMEOUT`	Timeout aborted signal, indicates a very long hit (> 100 ms)
`AFTER_TIMEOUT`	After timeout signal, indicates an artificially started hit after hit timeout
`DDT_TOO_SHORT`	DDT too short, indicates that channel(s) switched into "long duration mode" because the buffer has run half full
`SATURATION`	Saturation, indicates that the signal exceeds 95% of the input range
`PULSE_SENT`	Pulse (sent), indicates that the signal was generated by the test pulse (sending channel)
`PULSE_RECEIVED`	Pulse (received), indicates that the signal was generated by the test pulse (receiving channel)
`TR_TRIGGER`	TR trigger, indicates if transient data record belongs to a hit (only used in tradb)

AFTER_TIMEOUT = 256¶: After timeout signal, indicates an artificially started hit after hit timeout

DDT_TOO_SHORT = 512¶: DDT too short, indicates that channel(s) switched into “long duration mode” because the buffer has run half full

SATURATION = 16¶: Saturation, indicates that the signal exceeds 95% of the input range

PULSE_SENT = 2048¶: Pulse (sent), indicates that the signal was generated by the test pulse (sending channel)

PULSE_RECEIVED = 64¶: Pulse (received), indicates that the signal was generated by the test pulse (receiving channel)

TR_TRIGGER = 32768¶: TR trigger, indicates if transient data record belongs to a hit (only used in tradb)

bit_length()¶

Number of bits necessary to represent self in binary.

>>> bin(37)
'0b100101'
>>> (37).bit_length()
6

bit_count()¶

Number of ones in the binary representation of the absolute value of self.

Also known as the population count.

>>> bin(13)
'0b1101'
>>> (13).bit_count()
3

as_integer_ratio()¶

Return integer ratio.

Return a pair of integers, whose ratio is exactly equal to the original int and with a positive denominator.

>>> (10).as_integer_ratio()
(10, 1)
>>> (-10).as_integer_ratio()
(-10, 1)
>>> (0).as_integer_ratio()
(0, 1)
