/*! @class HFTextRepresenter
|
|
@brief An HFRepresenter that draws text (e.g. the hex or ASCII view).
|
|
|
|
HFTextRepresenter is an abstract subclass of HFRepresenter that is responsible for displaying text. There are two concrete subclass, HFHexTextRepresenter and HFStringEncodingTextRepresenter.
|
|
|
|
Most of the functionality of HFTextRepresenter is private, and there is not yet enough exposed to allow creating new representers based on it. However, there is a small amount of configurability.

/*! Given a rect edge, return an NSRect representing the maximum edge in that direction, in the coordinate system of the receiver's view. The dimension in the direction of the edge is 0 (so if edge is NSMaxXEdge, the resulting width is 0). The returned rect is in the coordinate space of the receiver's view. If the byte range is not displayed, returns NSZeroRect.
|
|
|
|
If range is entirely above the visible region, returns an NSRect whose width and height are 0, and whose origin is -CGFLOAT_MAX (the most negative CGFloat). If range is entirely below the visible region, returns the same except with CGFLOAT_MAX (positive).
|
|
|
|
This raises an exception if range is empty.

If the character is not displayed because it would be above the displayed range, returns {0, -CGFLOAT_MAX}. If it is not displayed because it is below the displayed range, returns {0, CGFLOAT_MAX}. As a special affordance, you may pass a byte index one greater than the contents length of the controller, and it will return the result as if the byte existed.
