Detailed Description

Class representing a link to an object within an HDF5 file. In order to store links in a container they have to be default constructable. A default constructed link has the type LinkType::ERROR. Instead of a node type only the handle to the parent is stored. Thus, the parent can also be a File which would identify the link as the link to the root group.

Constructor & Destructor Documentation

◆ Link() [1/3]

hdf5::node::Link::Link	(	const file::File &	file,
		const Path &	parent_path,
		const std::string &	link_name
	)

Parameters

file	reference to the file via which the link was accessed
parent_path	the object path to the links parent

◆ Link() [2/3]

hdf5::node::Link::Link ( )

default

Leaves a link of type LinkType::ERROR.

◆ Link() [3/3]

hdf5::node::Link::Link ( const Link & )

default

Member Function Documentation

◆ exists()

bool hdf5::node::Link::exists ( ) const

◆ file()

const file::File& hdf5::node::Link::file ( ) const

◆ is_resolvable()

bool hdf5::node::Link::is_resolvable ( ) const

◆ operator*()

Node hdf5::node::Link::operator* ( ) const

Return an instance to the node referenced by this particular link.

all intermediate links exist and the final link must be resolvable.

◆ parent()

Group hdf5::node::Link::parent ( ) const

Return a const reference to the parent group of the link.

◆ path()

Path hdf5::node::Link::path ( ) const

Return the actual path of the link in the file. This is basically the path of the parent group with the name of the link as a top element.

◆ target()

LinkTarget hdf5::node::Link::target ( const property::LinkAccessList & lapl = property::LinkAccessList() ) const

Return the path to the object which is reference by this link.

◆ type()

LinkType hdf5::node::Link::type ( const property::LinkAccessList & lapl = property::LinkAccessList() ) const
