Implementations

impl NDPluginFileBase

pub fn new() -> Self

pub fn create_file_name(&self) -> String

Construct the full file path from template/path/name/number.

Mimics C epicsSnprintf(buf, ..., template, filePath, fileName, fileNumber). Template uses printf-style: first %s → filePath, second %s → fileName, %d (with optional width/precision like %3.3d) → fileNumber.

pub fn temp_file_path(&self) -> Option<PathBuf>

Get the temp file path (if temp_suffix is set).

pub fn last_written_name(&self) -> &str

Return the full file name that was last written.

pub fn ensure_directory(&self) -> ADResult<()>

Create directory if needed. C ADCore behavior: createDir != 0 → create directories. Positive or negative values both trigger creation (negative = depth hint in C, but in practice create_dir_all handles any depth).

pub fn process_array( &mut self, array: Arc<NDArray>, writer: &mut dyn NDFileWriter, ) -> ADResult<()>

Process an incoming array according to the current file mode.

pub fn flush_capture(&mut self, writer: &mut dyn NDFileWriter) -> ADResult<()>

Flush capture buffer: open file, write all buffered arrays, close.

pub fn close_stream(&mut self, writer: &mut dyn NDFileWriter) -> ADResult<()>

Close stream mode.

pub fn is_open(&self) -> bool

pub fn set_mode(&mut self, mode: NDFileMode)

pub fn set_num_capture(&mut self, n: usize)

pub fn num_captured(&self) -> usize

pub fn mode(&self) -> NDFileMode

pub fn num_capture_target(&self) -> usize

pub fn capture_array(&mut self, array: Arc<NDArray>)

pub fn clear_capture(&mut self)
