Method Detail

doit

public static boolean doit(SpdStaticStreamGraph SSG,
                           FlatNode node)

See if we can generate input communication channel code without using a buffer. If true, then we can, and we have already generated the code. This assumes that bottomPeek == remaining == 0

Parameters:

SSG -

node -

Returns:

True if we can generate buffer-less code and we just did, or false we cannot, so we have to generate a code using a buffer in Buffered*Communication.java
