# GetQuadView Method

Get a quadratic read-only view on this expression. If this expression can be treated as a quadratic expression then the function returns a readonly view on the quadratic terms (including the constant term and linear terms if there are any). If the expression cannot be treated as a linear expression then an exception is raised. In order to test this expression can be treated as quadratic, use function [!:.GetMaxDegree()] and check whether it returns 0, 1, or 2. In the returned System.Collections.Generic.KeyValuePair instances the constant term is indicated with a key with two NULL_VARIABLEs. Linear terms are represented by a QPair with NULL_VARIABLE as second variable. Note that depending on the actual expression class and its implementation, the terms may not be presented in the same order in which you added them. There may also be multiple elements with the same key (again depending on the implementation of the actual object).
