This will help determine if you get any added benefits from inlining. The best approach would be to hold off inlining until you finish profiling your program. This is a cost to build and development time. As correctly declaring these statements critically depends on the logical conditional, let us first take a closer look at working with logical expressions in R. The problem with practical coupling is that when the inlined callee changes, you have to recompile the caller.

Inlining increases practical coupling by making the caller potentially rely on the inlined code's internal implementation details.

However, if the function is not called frequently, it will not have visible runtime improvement.

In most cases, inlining could improve execution time by avoiding the call overhead, and possible see-through by the optimizer (making it a non-opaque function) for more optimizing opportunities.

But in some cases, when the function size is smaller than the function call code size, inlining could reduce program size. In most cases, inlining increase program size.Using the 'inline' specifier is only a suggestion to the compiler that an inline expansion can be performed the compiler is free to ignore the suggestion. This eliminates call-linkage overhead and can expose significant optimization opportunities. Because 1 equals 1, the string Equal is returned from the else clause of the second inline if statement.An inline function is one for which the compiler copies the code from the function definition directly into the code of the calling function rather than creating a separate set of instructions in memory. If 1 evaluates as less than 1, the string Less Than is returned.

In this case, if 1 does not equal 1, the second inline if statement is evaluated as part of the else clause of the first inline if statement. If you want to nest inline if statements, (that is, use one inline if statement as an expression for another inline if statement), enclose the nested inline if statements in parentheses: (1 != 1 ? 'Not Equal' : (1 < 1 ? 'Less Than': 'Equal') ) If isMember does not equal the string Yes, Not a Member is returned. In this case, if isMember equals the string Yes, Member is returned. You can also use the comparison operator: ((isMember = 'Yes' ) ? 'Member' : 'Not a member') IMHO, the inline operator is far more readable than the if block- plus in the inline case it is far more obvious that you are doing a simple conditional string assignment. If isMember is false, Not a Member is returned. In this case, if isMember is true, Member is returned. (condition?2:10)įor example, to display one message if a variable is true and another message if the variable is false, you can use this statement: ( isMember ? 'Member' : 'Not a member') You can safely eliminate the condition parentheses, but omitting the quotes can cause problems.
