Subject: all decoders: introduce a reset() method
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=10aeb8ea8b183394cebc0033f048f49f4262b57d;p=libsigrokdecode.git

all decoders: introduce a reset() method

Move initialization code of protocol decoders from the constructor to a
new reset() helper method. The libsigrokdecode backend could run this
method several times to clear the decoder's internal state, before new
data from another acquisition gets fed to decode() calls.
