Member Function Documentation

size()

int CppCrate::Record::size

(

)

const

value() [1/2]

Value CppCrate::Record::value

(

int

pos

)

const

Returns the value at position pos or an empty value if pos is invalid.

value() [2/2]

Value CppCrate::Record::value

(

const std::string &

name

)

const

Returns the value with the name name or an empty value if name does not exists.

Note

This value is slower than the index based variant. So if you know the value's position you might want to use value() with the index.
