This implies that:. SOQL defines several escape sequences that are valid in queries so that you can include special characters in your queries. Each top-level global or public class starts with an ApexDoc on the first line, containing a high level description of its purpose.
The order you choose for the members and initializers of your class can have a great effect on learnability. What is important is that each class uses some logical order , which its maintainer could explain if asked. When a class has multiple constructors, or multiple methods with the same name, these appear sequentially, with no other code in between not even private members.
Terminology Note: block-like construct refers to the body of a class, method or constructor. Note that, by Section 4. Braces are used with if , else , for , do and while statements, even when the body is empty or contains only a single statement. Apex properties may be written like:. Each time a new block or block-like construct is opened, the indent increases by two spaces. When the block ends, the indent returns to the previous indent level.
The indent level applies to both code and comments throughout the block. See the example in Section 4. Apex code has a column limit of characters. Except as noted below, any line that would exceed this limit must be line-wrapped, as explained in Section 4.
Terminology Note: When code that might otherwise legally occupy a single line is divided into multiple lines, this activity is called line-wrapping. There is no comprehensive, deterministic formula showing exactly how to line-wrap in every situation.
Very often there are several valid ways to line-wrap the same piece of code. Tip: Extracting a method or local variable may solve the problem without the need to line-wrap. The prime directive of line-wrapping is: prefer to break at a higher syntactic level. Note: The primary goal for line wrapping is to have clear code, not necessarily code that fits in the smallest number of lines.
In general, two continuation lines use the same indentation level if and only if they begin with syntactically parallel elements. Section 4. Beyond where required by the language or other style rules, and apart from literals, comments and ApexDoc, a single ASCII space also appears in the following places only. This rule is never interpreted as requiring or forbidding additional space at the start or end of a line; it addresses only interior space.
Terminology Note: Horizontal alignment is the practice of adding a variable number of additional spaces in your code with the goal of making certain tokens appear directly below certain other tokens on previous lines. This practice is permitted, but is never required by NimbleUser Style. It is not even required to maintain horizontal alignment in places where it was already used.
Tip: Alignment can aid readability, but it creates problems for future maintenance. Consider a future change that needs to touch just one line. This change may leave the formerly-pleasing formatting mangled, and that is allowed. More often it prompts the coder perhaps you to adjust whitespace on nearby lines as well, possibly triggering a cascading series of reformattings. Optional grouping parentheses are omitted only when author and reviewer agree that there is no reasonable chance the code will be misinterpreted without them, nor would they have made the code easier to read.
It is not reasonable to assume that every reader has the entire Apex operator precedence table memorized. After each comma that follows an enum constant, a line break is optional. Additional blank lines usually just one are also allowed. This is one possibility:. An enum with no documentation on its constants may optionally be formatted as if it were an list initializer see Section 4.
Local variables are not habitually declared at the start of their containing block or block-like construct. Instead, local variables are declared close to the point they are first used within reason , to minimize their scope. Local variable declarations typically have initializers, or are initialized immediately after declaration. Annotations applying to a class, method or constructor appear immediately after the documentation block, and on a line of its own.
These line breaks do not constitute line-wrapping Section 4. Exception: A single parameterless annotation may instead appear together with the first line of the signature, for example:. This section addresses implementation comments. ApexDoc is addressed separately in Section 7, ApexDoc.
Any line break may be preceded by arbitrary whitespace followed by an implementation comment. Such a comment renders the line non-blank. Block comments are indented at the same level as the surrounding code. Class and member modifiers, when present, appear in the order recommended by the Apex Language Specification:. Long -valued integer literals use an uppercase L suffix, never lowercase to avoid confusion with the digit 1. For example, L rather than l. Identifiers use only ASCII letters and digits, and, in a small number of cases noted below, underscores.
The platform reserves use of two consecutive underscores in a name double underscore. A double underscore cannot be used in a developer name.

Compares two strings lexicographically, based on the Unicode value of each character in the Strings. contains(substring) Returns true if and only if the String. Actually Apex strings do have a contains method, unlike a lot of it returns true if the sequence of characters appears in the String. feri.patrick-kinn.online › apex › apex_strings.
