Methods

- (Single) ContentSizeForBoxSize(FlexItem, Axis, Single)

Parameters
FlexItem element
Axis axis
Single boxLength
Returns
Single

- (Single) ConvertBorderLengthToOuterLength(FlexItem, Axis, Single, Nullable)

Parameters
FlexItem element
Axis axis
Single borderSize
Nullable<Single> effectiveContainerInnerSize
Returns
Single

- (ContentLength) ConvertBoxLengthToInnerLength(FlexItem, Axis, BoxLength, Func<>>)

Parameters
FlexItem element
Axis axis
BoxLength boxSize
Func<Nullable<Single>> effectiveContainerInnerSize
Returns
ContentLength

- (ContentLength) ConvertBoxLengthToInnerLength(RootFlexContainer, BoxLength)

RFC's aren't allowed FlexItem's, so all their Box/Content/Outer/Inner/Padding/Margins values are - by definition - the same

Parameters
RootFlexContainer rfc
BoxLength boxSize
Returns
ContentLength

- (Single) ConvertBoxLengthToOuterLength(FlexItem, Axis, Single, ContentLength, Boolean)

Spec: https://www.w3.org/TR/css-sizing-3/#outer-size

Outer Size === "content_box + padding + border + margins" -- i.e. the outermost variant of a CSS Box

Note: Requires that the size passed in is the 'box' size, which depends on the element's boxmode (CONTENT_BOX vs BORDER_BOX etc)

Parameters
FlexItem element
Axis axis
Single boxSize
ContentLength effectiveContainerInnerSize
Boolean debug
Returns
Single

- (ContentLength) ConvertOuterLengthToInnerLength(FlexItem, Axis, Single, ContentLength)

Note: "inner" length is the same as "content" length by definition, Note: "outer" length is the same as "margin-box" length by definition

i.e. this ALWAYS subtracts BOTH the padding AND the margins

Parameters
FlexItem item
Axis axis
Single outerLength
ContentLength effectiveContainerInnerSize
Returns
ContentLength
