Class IloTextureParam

Parameters are used to change the default behavior and characteristics of activities and resources. An instance of IloTextureParam modifies the existence and type of texture measurement that is created on a resource. By default, no texture measurement is created.

Texture measurements are measurements of some aspect of the search state and can be used to guide heuristics. See Texture Measurements.

For more information, see Texture Measurements.

This constructor creates a new instance of IloTextureParam, with the default value that no texture measurement will be created.

This member function adds an interval list to the list of intervals that are ignored by the texture measurement. The new intervals are merged with existing intervals that they overlap, if any.

This member function adds an interval to the list of intervals that are ignored by the texture measurement. The ignored interval is [start, end). The new interval is merged with existing intervals that it overlaps, if any.

This member function adds an interval to the list of intervals that are ignored by the texture measurement. The ignored interval is [start, start+duration). The new interval is merged with existing intervals that it overlaps, if any.

This member function adds a set of intervals to the list of intervals that are ignored by the texture measurement. For every i >= 0 such that start + i * period < end, an interval of [start + i * period, start + duration + i * period) is added. Adding a new interval that overlaps with an already existing interval results in the merging of the intervals.

This member function removes all the intervals from the ignored intervals of the invoking parameter.

This member function returns a list of intervals that will be ignored by the texture measurements. No texture calculations will take place on these intervals and the criticality value for all time points within the intervals is 0.

This member function removes all intervals ignored by the texture measurement during the intervals in the interval list.

This member function removes all intervals ignored by the texture measurement between start and end. If start is inside an existing interval [start1, end1), that is, start1 < start < end1, this results in an ignored interval [start1, start). If end is inside an interval [start2, end2) this results in an ignored interval [end, end2).

This member function removes all ignored intervals on the invoking parameter between start and start+duration.

This member function removes ignored intervals from the invoking parameter. More precisely, for every i >= 0 such that start + i * period < end, this function removes all intervals between start + i * period and start + duration + i * period.

This member function sets the texture criticality calculator object given as argument as the criticality calculator of the invoking texture parameter.

This member function sets the beta value to be used with the random number generator. If no random number generator is used, this function does nothing. For details on the use of the beta argument, see IlcResourceTexture::setRandomGenerator.

This member function sets the random number generator to be used in choosing the critical time point on the texture measurement. By default, no random number generator is used.

This member function sets the texture factory object given as argument as the texture factory of the invoking texture parameter.

This member function removes the random number generator, meaning that no random numbers will be used in choosing the critical time point on the texture measurement.
