utility routine
Học thuậtThân thiện
Definition
Noun: A utility routine is a self-contained piece of computer code designed to perform a specific, common, and practical task. It is a general-purpose subroutine or function that is not part of the core logic of a program but is available to be called ("used as needed") to handle standard operations, such as sorting data, managing files, or performing mathematical calculations.
Usage
This term is used in the context of computer programming and software engineering. It describes a reusable code module that provides a helpful service. * Programmers write utility routines to avoid duplicating code for common tasks. * A utility routine is often stored in a library so it can be easily accessed by different parts of a program or by different programs.
Examples
- "The software library includes a utility routine for converting dates between different formats."
- "Instead of writing new code, the developer called an existing utility routine to sort the array."
- "Common utility routines include functions for input/output operations, string manipulation, and memory management."
Advanced Usage
- Distinction from Core Logic: A utility routine is typically separate from the main application's business logic. It handles ancillary but necessary tasks that support the primary function.
- System Utility: At the operating system level, a utility routine might refer to a low-level function that performs a fundamental service, like allocating memory or handling an interrupt.
Variants and Related Words
- Utility Function: A very close synonym, often used interchangeably, though "function" can imply a specific return value.
- Service Routine: Another synonym emphasizing the routine's role in providing a service to other parts of the program.
- Library Routine: A routine stored in a code library, which is often a utility routine.
- Helper Function / Method: A more informal term for a utility routine that assists other functions.
Synonyms
- Service routine
- Helper function
- Common function
- Tool routine
Related Phrases
- Utility Software: This is a related but distinct concept. It refers to an entire application (e.g., a disk defragmenter, antivirus scanner) designed for system maintenance, not a single routine within a program.
- Call a utility routine: The standard phrase for using it.
- Example: "The main program calls a utility routine to log error messages."
Noun
- a routine that can be used as needed
