Struct opencv::core::FileNodeIterator

pub struct FileNodeIterator { /* private fields */ }

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.

Implementations

impl FileNodeIterator

pub fn default() -> Result<FileNodeIterator>

The constructors.

These constructors are used to create a default iterator, set it to specific element in a file node or construct it from another iterator.

pub fn new( node: &impl FileNodeTraitConst, seek_end: bool ) -> Result<FileNodeIterator>

The constructors.

These constructors are used to create a default iterator, set it to specific element in a file node or construct it from another iterator.

Overloaded parameters

Parameters

• node: File node - the collection to iterate over; it can be a scalar (equivalent to 1-element collection) or “none” (equivalent to empty collection).
• seekEnd: - true if iterator needs to be set after the last element of the node; that is: * node.begin() => FileNodeIterator(node, false) * node.end() => FileNodeIterator(node, true)

pub fn copy(it: &impl FileNodeIteratorTraitConst) -> Result<FileNodeIterator>

The constructors.

These constructors are used to create a default iterator, set it to specific element in a file node or construct it from another iterator.

Overloaded parameters

Parameters

• it: Iterator to be used as initialization for the created iterator.
