Member Function Documentation

constexpr int Mdt::ItemModel::Range::count ( ) const

inlineprotectednoexcept

Get count.

Returns count of element in this range if it is valid, otherwise 0.

See also: isValid()

Definition at line 127 of file Range.h.

constexpr int Mdt::ItemModel::Range::first ( ) const

inlineprotectednoexcept

Get first.

Warning: first is returned as it was set. The validity of this range should be checked before using the returned value.

See also: isValid()

Definition at line 86 of file Range.h.

constexpr bool Mdt::ItemModel::Range::isNull ( ) const

inlinenoexcept

Check if range is null.

This is the same as isEmpty()

See also: isEmpty()

Definition at line 64 of file Range.h.

constexpr bool Mdt::ItemModel::Range::isValid ( ) const

inlinenoexcept

Check if range is valid.

This range is valid if:

Both first and last are >= 0
Last is >= first

Definition at line 46 of file Range.h.

constexpr int Mdt::ItemModel::Range::last ( ) const

inlineprotectednoexcept

Get last.

Warning: last is returned as it was set. The validity of this range should be checked before using the returned value.

See also: isValid()

Definition at line 106 of file Range.h.

constexpr void Mdt::ItemModel::Range::setCount ( int count )

inlineprotectednoexcept

Set count.

Note: This method must be called after setFirst()

Definition at line 115 of file Range.h.
