flushTrue

FlushTrue is a term used in some programming contexts to describe a boolean flag or parameter that requests an immediate flush of a buffered data path, such as an I/O buffer, a log buffer, or a transactional cache. The name itself is a combination of flush and True, and it typically appears in code where a descriptive, explicit option is preferred over a generic flush control. There is no standardized specification for a feature universally called flushTrue; its exact syntax and location vary between languages and libraries.

Because the concept of flushing is common across software systems—emptying a buffer to push data to its destination—flushTrue or similarly named options are often discussed in relation to output streams, logging frameworks, database clients, and graphics pipelines. In practice, developers may encounter internal flags, keyword arguments, or configuration settings that enable immediate flushing when set to true. While similar in spirit to typical autoflush or flush options, flushTrue is not a universal keyword and should be interpreted according to the surrounding API documentation.

Usage considerations include the trade-off between immediacy and performance. Forcing a flush on every write can reduce buffering benefits and increase I/O overhead, potentially affecting throughput. Therefore, flushTrue-style flags are usually employed selectively, in situations requiring low-latency visibility or strong durability guarantees.

In summary, flushTrue is a descriptively named flag used in some codebases to indicate an explicit, immediate flush, but it is not a standardized term and its exact behavior depends on the specific API.
