| canContainChildren | | public boolean canContainChildren(Object o)(Code) | | |
| canResolve | | public boolean canResolve(Object o)(Code) | | Determines if the passed in Object is an instance of an object for which

o - true if this class can act as a surrogate for the passed in object. |
| getAspects | | public Object[] getAspects(Object o)(Code) | | Returns the aspects of the passed in object. This method is only called
hasAspects() returns true. Aspects act like children but do not include a
line from them to the parent-to-child branch and can be exposed without
expanding the parent to show the children. Unlike children, aspects can

| hasAspects | | public boolean hasAspects(Object o)(Code) | | Indicates if this object has aspects. Aspects act like children
but do not include a line from them to the parent-to-child branch and
