Returns

string view over the name of the node

next()

GenericDataNode LLU::GenericDataNode::next ( ) const

noexcept

Get GenericDataNode wrapper over the next node.

Returns

next node wrapped in GenericDataNode

operator bool()

LLU::GenericDataNode::operator bool ( ) const

explicit

Bool conversion operator.

Returns

true iff the node is not null

operator->()

GenericDataNode* LLU::GenericDataNode::operator-> ( )

inline

Member of pointer operator, used by DataList iterators.

type()

MArgumentType LLU::GenericDataNode::type ( ) const

noexcept

Get type of the node value.

Returns

type of the node value

value()

Argument::TypedArgument LLU::GenericDataNode::value

(

)

const

Get value of the node as the variant type.

Returns

TypedArgument variant holding the value of the node
