Detailed Description

Template specialization of the ac2lsl bridge to take care of complex numbers.

This specialization is needed because lsl does not support complex numbers. Order is [re(0), im(0), re(1), im(1), ....]

Constructor & Destructor Documentation

save_var_t()

ac2lsl::save_var_t< mha_complex_t >::save_var_t ( const std::string &  name_, const std::string &  type_, unsigned  num_channels_, const mha_real_t  rate_, const lsl::channel_format_t  format_, const std::string &  source_id_, void *  data_  )

inline

C'tor of specialization for complex types.

See generic c'tor for details.

Member Function Documentation

get_buf_address()

virtual void* ac2lsl::save_var_t< mha_complex_t >::get_buf_address ( ) const

inlineoverridevirtualnoexcept

Implements ac2lsl::save_var_base_t.

set_buf_address()

virtual void ac2lsl::save_var_t< mha_complex_t >::set_buf_address ( void *  data )

inlineoverridevirtual

Implements ac2lsl::save_var_base_t.

info()

virtual lsl::stream_info ac2lsl::save_var_t< mha_complex_t >::info ( ) const

inlineoverridevirtualnoexcept

Get buffer address as void pointer.

Returns

Adress of the data buffer

Implements ac2lsl::save_var_base_t.

data_type()

virtual unsigned ac2lsl::save_var_t< mha_complex_t >::data_type ( ) const

inlineoverridevirtualnoexcept

Cast the input pointer to the appropriate type and set the buffer address.

Parameters

data	New buffer address

Implements ac2lsl::save_var_base_t.

send_frame()

virtual void ac2lsl::save_var_t< mha_complex_t >::send_frame ( unsigned  num_entries )

inlineoverridevirtual

Send a frame of complex types.

Complex numbers are stored as alternating real and imaginary parts. An array of complex numbers in memory can be reinterpreted as a vector of real numbers that correspond to real and imaginary parts. LSL does not support complex types directly. Send one vector containing {buf[0].re,buf[0].im,buf[1].re,buf[1].im,...} instead.

Implements ac2lsl::save_var_base_t.

Interface to lsl

buf

mha_complex_t* ac2lsl::save_var_t< mha_complex_t >::buf

private
