Class Documentation

class SawtoothSequence : public ska::pst::common::ByteSequence

Generates a sawtooth pattern of floating point values.

Public Functions

virtual void configure(const ska::pst::common::AsciiHeader &config) override

Configure the Sawtooth Sequence using AsciiHeader parameters.

Parameters

config – configuration including all of the following parameters

  • SAWTOOTH_NSAMP number of samples per sawtooth (period)

  • SAWTOOTH_FIRST amplitude of first sample in sawtooth

  • SAWTOOTH_LAST amplitude of last sample in sawtooth

virtual void generate(char *buffer, uint64_t bufsz) override

Generate a sequence of floating point sawtooth samples.

Parameters

  • buffer – pointer to memory to which the sequence will be written

  • bufsz – number of bytes to write to the buffer

virtual void reset() override

Reset the internal state of the sequence The next call to generate or validate will behave as per the first call to these functions.

virtual bool validate(char *buffer, uint64_t bufsz) override

Compare contents of buffer to expected sawtooth sequence.

Parameters

  • buffer – pointer to memory containing bytes to be validated

  • bufsz – number of bytes to validate in the buffer

Returns

true if all bytes are valid
