References all the subattributes of a group that have the same name.
Library: ilvproto
IlvGroupUserAccessor
is used to change and/or query a value for all the nodes in a group. It defines a global value that is dispatched to all the nodes in the group. In a programming language, this accessor would be similar to a pointer to a collection of attributes of the same name.
IlvGroupUserAccessor::IlvGroupUserAccessor | ( | const char * | name, |
IlvValueTypeClass * | type | ||
) |
Initializes a new group accessor.
When the value specified by name is changed for a group, the same value change will be forwarded to all the nodes of the group. When the value is queried for a group, it will be queried from all the nodes of the group, and the last value will be returned.

Compares the values in ref and object and returns the differing values.
Compares the objects object and ref for the values specified by the values array of length count.
The default implementation simply calls the IlvAccessible::compareValues(const IlvAccessible*, IlvValue*, IlUShort, IlvValueArray&) const
method, which will query the values for the two objects and compare them one by one. Subclasses may compare values more cleverly by grouping differences: for example, the IlvGroupAccessor
subclass detects when all nodes of a group differ homogeneously and reports only one difference for the whole group.
object | The object to compare. |
ref | The reference to compare to. |
values | The values to be compared. |
count | The number of elements in the array values. |
diffs | Where the differences are stored. |
Reimplemented from IlvUserAccessor.
