Deciphering object oriented programming concepts in Java -



Deciphering object oriented programming concepts in Java -

i've been reading object oriented concepts, , i'm getting lost. conceptually, understand method "does" , class "blueprint". i've read analogies, thing makes sense me far is: loops,if then, variable assignments, primitive info types, , basic syntax.

to me, programme program program. type in instructions, , computer executes. guess don't see big picture.

the biggest part of oop sky view, organization , code reuse. want organize 'objects' particular thing , want able reuse other applications well. thought makes easier maintain doing , info , how working together. broad allow me know not understanding.

bundling code individual software objects provides number of benefits, including:

modularity: source code object can written , maintained independently of source code other objects. 1 time created, object can passed around within system. information-hiding: interacting object's methods, details of internal implementation remain hidden outside world. code re-use: if object exists (perhaps written software developer), can utilize object in program. allows specialists implement/test/debug complex, task-specific objects, can trust run in own code. pluggability , debugging ease: if particular object turns out problematic, can remove application , plug in different object replacement. analogous fixing mechanical problems in real world. if bolt breaks, replace it, not entire machine.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...
