drools - Event sequencing -



drools - Event sequencing -

i'm new in drools , cep. i'm trying solve issue events processing - derive complex events sequences of atomic events.

for example, sequence of a, b , c atomic events d complex event.

how can solve issue drools rule engine , drools fusion axtention? may be, there other tools or java frameworks (math methods or algorithms) solve kind of issues?

a rule test 3 events in sequence:

rule abc when $a: a() $b: b( after $a ) $c: c( after $b ) // ... end

there many details clarified - in reality may not simple that, question doesn't provide information.

see drools manual - section on event processing has similar (and more complex) examples.

drools cep drools-fusion

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
