The IsEmpty property of the NodeQuery struct in the Editor.NodeEditor namespace indicates whether the node query is empty. This property returns a boolean value, where true signifies that the node query does not contain any elements, and false indicates that it does contain elements.
Use the IsEmpty property to quickly check if a NodeQuery instance has any elements. This can be useful for conditional logic where operations should only be performed on non-empty queries.
// Example of using the IsEmpty property
// Assume nodeQuery is an instance of NodeQuery
NodeQuery nodeQuery = new NodeQuery();
// Check if the node query is empty
if (nodeQuery.IsEmpty)
{
// Handle the case where the node query is empty
// For example, log a message or skip processing
}
else
{
// Proceed with operations on the non-empty node query
}
