Method Detail

checkForSameDefinition

protected final boolean checkForSameDefinition(DefinitionalObject other)

Checks to determine if another instance has the same definition as this instance and returns true if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Specified by:

checkForSameDefinition in class DefinitionalObject

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

checkForSameDefinition

protected abstract boolean checkForSameDefinition(SegmentPropagatorConstraint other)

Checks to determine if another instance has the same definition as this instance and returns true if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

computeCurrentDefinitionHashCode

protected int computeCurrentDefinitionHashCode()

Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the SegmentPropagatorConstraint.checkForSameDefinition(agi.foundation.infrastructure.DefinitionalObject) method.

Overrides:

computeCurrentDefinitionHashCode in class DefinitionalObject

Returns:

The computed hash code.

enumerateDependencies

public void enumerateDependencies(DependencyEnumerator enumerator)

Enumerates the dependencies of this object by calling DependencyEnumerator#enumerate(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class.

Specified by:

enumerateDependencies in interface IEnumerateDependencies

Overrides:

enumerateDependencies in class DefinitionalObject

Parameters:

enumerator - The enumerator that is informed of the dependencies of this object.

freezeAggregatedObjects

protected void freezeAggregatedObjects()

Called by DefinitionalObject.freeze() to also freeze any objects that are considered to be a part of this object. Derived classes which contain additional aggregated objects MUST override this method, call the base implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be frozen in this method are frequently created in this object's constructor and are not settable via properties.

Overrides:

freezeAggregatedObjects in class DefinitionalObject

getDesiredValue

public final ValueDefinition<Double> getDesiredValue()

Gets the threshold that the evaluated value will be compared to when solving for a particular trajectory. This value must not vary in time; consider using a ParameterizedValueDefinition if you want to change this value at propagation time.

setDesiredValue

public final void setDesiredValue(ValueDefinition<Double> value)

Sets the threshold that the evaluated value will be compared to when solving for a particular trajectory. This value must not vary in time; consider using a ParameterizedValueDefinition if you want to change this value at propagation time.

getSettings

public final SolverConstraintSettings getSettings()

Gets the settings for the MultivariableFunctionSolver or ParameterOptimizer associated with this constraint.

setSettings

public final void setSettings(SolverConstraintSettings value)

Sets the settings for the MultivariableFunctionSolver or ParameterOptimizer associated with this constraint.

getName

public final String getName()

Gets an optional name to identify this constraint.

setName

public final void setName(String value)

Sets an optional name to identify this constraint.

getEvaluator

@Nonnull
public abstract SegmentPropagatorConstraintEvaluator getEvaluator(@Nonnull
                                                                            EvaluatorGroup group)

Creates and returns the SegmentPropagatorConstraintEvaluator.

Derived classes should call SegmentPropagatorConstraint.validateProperties() to check properties owned by this base class, as well as validate their own properties.

Parameters:

group - The EvaluatorGroup to use to create any necessary evaluators for this constraint.

Returns:

The fully configured constraint evaluator.

validateProperties

protected void validateProperties()

Validates that required properties are configured correctly in order to get an evaluator for this instance. Derived classes should call this method when implementing SegmentPropagatorConstraint.getEvaluator(agi.foundation.EvaluatorGroup), as well as validate their own properties.

Throws:

PropertyInvalidException - Thrown when Settings (get / set) or DesiredValue (get / set) is null, or Scaling (get / set) is null, or Tolerance (get / set) is not greater than zero.
