Class Overview

The measurespec class encapsulates the layout requirements that are passed from the parent container to the Child view. Each measurespec object represents a width and/or height requirement, which consists of a size and a mode. The mode is as follows:

Unspecified

The parent container does not impose any constraints on the Child view. It can be any size it wants.

Exactly

The parent container determines the exact size of the Child view. Subviews are given their boundaries, regardless of the actual size of the view.

At_most

The size of a child view can be as large as the size specified by the Child view. This class provides a method to compress <size, mode> and decompress it into integers.

Constants
Int	At_most	Measurement specification mode: The child view can be as large as the size specified by it.
Int	Exactly	Measurement specification mode: the parent container determines the precise size of the Child view.
Int	Unspecified	Measurement specification mode: the parent container does not forcibly restrict the size of the Child view.

Public Methods
static int	getmode (INT measurespec) extract measurement modes from the provided measurement specifications. parameter measurespec: Measure specifications to extract measurement modes return value unspecified, at_most or exactly
static int	getsize (INT measurespec) extract dimensions from provided measurement specifications parameter measurespec to extract measurement specifications for measurement dimensions return value dimensions defined in pixels in the provided measurement specifications.
static int	makemeasurespec (INT size, int Mode) creates a measurement specification based on the specified size and mode. The mode must be one of the following values: unspecified exactly at_most parameter siz E measurement specification size mode: standard mode return value A measurement specification based on the specified size and mode.
Static string	Tostring (INT measurespec) Returns the string representation of the specified measurement specification. Parameters Measure specification for converting measurespec to a string Return Value A string in the format of "measurespec: mode size.
