Example 36 with Omit_Value

use of org.eclipse.titan.designer.AST.TTCN3.values.Omit_Value in project titan.EclipsePlug-ins by eclipse.

the class Integer_Type method checkThisValueLimit.

/**
 * Checks if a given value is a valid integer limit.
 * <p>
 * The special float values infinity and -infinity are valid integer range limits too.
 *
 * @param timestamp the time stamp of the actual semantic check cycle.
 * @param value the value to be checked
 * @param expectedValue the kind of the value to be expected
 * @param incompleteAllowed true if an incomplete value can be accepted at the given location, false otherwise
 * @param omitAllowed true if the omit value can be accepted at the given location, false otherwise
 * @param subCheck true if the subtypes should also be checked.
 * @param implicitOmit true if the implicit omit optional attribute was set for the value, false otherwise
