android - Call extension function inside java class as any RX operator -


i created extension function,

fun <t> observable<t>.subscribewitherrorhandling(onnext: (t) -> unit ,onerror: ((throwable: throwable) -> unit)? = null): subscription { //doing stuff }

in kotlin class, able use no problem in way

observable.subscribewitherrorhandling(...)

now, want use function in java class well. see can call statically :

myextensionfile.subscribewitherrorhandling

but in case, need else since it's middle of rx flow. , part i'm stuck with. possible? or no way java code?

simple answer. no.

explanation - believe that's not possible since mean you're extending observableclass abstract. kotlin extensions add same functionality moving out of inheritance tree , in java in you're pretty stuck inheritance.

so option left extend base observable class , create own implementation of same think unwanted in case. simple solution create new method java can take observable , required logic. or create custom class observable instance instance member , write required methods inside (the standard oops way). code used kotlin java.

edit: believe know still point question.

how use roscolor() ignore value (like empty cell) ? color row if value upper 5 when there nothing in cell, want ignore roscolor() apply, how? public sub roscolor() integer = 0 quotedatagridview1.rows.count() - 1 step +1 dim val integer val = quotedatagridview1.rows(i).cells(3).value if val = vbempty quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.white elseif val < 5 quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.red elseif val > 5 , val < 10 quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.lightyellow end if next end sub you can check empty value following public sub roscolor() integer = 0 quotedatagridview1.rows.count() - 1 step +1 dim val = quotedatagridview1.rows(i).cells(3).value if isdbnull(val) or val nothing quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.white ...

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
