Method Details

append(iConstraint)

Appends a Constraint to the constraint manager.

Parameters:

iConstraint (Constraint) - The constraint to append.

Returns: None

at(iIndex)

Retrieves the Constraint at the specified index.

Parameters:

iIndex (int) - The index of the contraint to retrieve.

Returns: Constraint

check(iConstraint)

Checks to see if adding the provided constraint will result in an overdefined system.

Parameters:

iConstraint (Constraint) - The constraint to check.

Returns: bool

insert(iIndex, iConstraint)

Inserts a Constraint.

Parameters:

iIndex (int) - The position to insert the constraint.
iConstraint (Constraint) - The constraint to insert.

Returns: None

remove(iIndex)

Removes a Constraint.

Parameters:

iIndex (int) - The position of the constraint to remove.

Returns: None

removeOrphanedConstraints()

This method cycles through all defined constraints and determines if they are referencing geometry that is no longer present. Any that meet this condition are removed.

Returns: None
