Struct opencv::core::FileNodeIterator

pub struct FileNodeIterator { /* fields omitted */ }

used to iterate through sequences and mappings.

A standard STL notation, with node.begin(), node.end() denoting the beginning and the end of a sequence, stored in node. See the data reading sample in the beginning of the section.

Methods

impl FileNodeIterator

pub fn as_raw_FileNodeIterator(&self) -> *mut c_void

pub unsafe fn from_raw_ptr(ptr: *mut c_void) -> Self

impl FileNodeIterator

pub fn read_raw(
    &mut self,
    fmt: &str,
    vec: &mut u8,
    len: size_t
) -> Result<FileNodeIterator>

Reads node elements to the buffer with the specified format.

Usually it is more convenient to use operator >> instead of this method.

Parameters

• fmt: Specification of each array element. See @ref format_spec "format specification"
• vec: Pointer to the destination array.
• len: Number of bytes to read (buffer size limit). If it is greater than number of remaining elements then all of them will be read.

C++ default parameters

• len: (size_t)INT_MAX
