//! This class supports the following properties:
|
|
//!
|
|
//! .endpoint - the ZMQ endpoint to be connected to
|
|
//! .vlen - vector length of the input items (default 1, one item)
|
|
//! this must match the size of the publisher!
|
|
//! .pass_tags - boolean flag if tags should be propagated (default false)
|
|
//! .timeout_ms - receive timeout, in milliseconds (default 100)
|
|
//! .hwm - ZMQ high water mark (default -1, ZMQ default)
|
|
//!
|
|
//! .item_type - data type of the samples (default "gr_complex")
|
|
//!
|
|
//! (probably should be abstracted to the base class)
|
|
//!
|
|
//! .dump - whether to archive input data
|
|
//! .dump_filename - if dumping, path to file for output
|
|
