This templated class abstractly represents the external environment under which a top-level graph object executes. It provides a mechanism to source/sink input/output data that is consumed/produced during graph execution.
Constructor
simulation::platform<#in,#out> (IOAttr* in_0,..., IOAttr* out_0,...);This platform constructor is provided for software simulation purposes. The template parameters #in and #out are non-negative integers specifying the number of input and output ports supported by this abstract platform object. The constructor takes as many I/O attribute specification arguments as the sum of input and output ports: first all output attributes, then all input attributes. Output platform attributes feed external data to graph inputs, and input platform attributes receive graph output data for external consumption.
An I/O attribute specification is either FileIO, GMIO, or PLIO objects, and is declared separately. A direct
std::string argument can also be used to
represent a FileIO attribute object.
Member Variables
std::vector<port<output>> src;This variable provides access to the output attributes of a platform in the form of an output port, allowing connections between platform outputs and graph inputs to be specified. The i'th index selects the i'th output port (window, stream, or RTP) declared in the platform constructor arguments.
std::vector<port<input>> sink;This variable provides access to the input attributes of a platform in the form of an input port, allowing connections between graph outputs and platform inputs for be specified. The i'th index selects the i'th input port (window, stream, or RTP) declared in the platform constructor arguments.
