## Functions

template<typename PointDataTreeT>
void | appendAttribute (PointDataTreeT &tree, const Name &name, const NamePair &type, const Index strideOrTotalSize=1, const bool constantStride=true, const Metadata *defaultValue=nullptr, const bool hidden=false, const bool transient=false)
| Appends a new attribute to the VDB tree (this method does not require a templated AttributeType)
template<typename ValueType, typename CodecType = NullCodec, typename PointDataTreeT>
void | appendAttribute (PointDataTreeT &tree, const std::string &name, const ValueType &uniformValue=point_attribute_internal::Default< ValueType >::value(), const Index strideOrTotalSize=1, const bool constantStride=true, const TypedMetadata< ValueType > *defaultValue=nullptr, const bool hidden=false, const bool transient=false)
| Appends a new attribute to the VDB tree.
template<typename ValueType, typename PointDataTreeT>
void | collapseAttribute (PointDataTreeT &tree, const Name &name, const ValueType &uniformValue=point_attribute_internal::Default< ValueType >::value())
| Collapse the attribute into a uniform value.

| Drops attributes from the VDB tree.
template<typename PointDataTreeT>
void | dropAttributes (PointDataTreeT &tree, const std::vector< Name > &names)
| Drops attributes from the VDB tree.
template<typename PointDataTreeT>
void | dropAttribute (PointDataTreeT &tree, const size_t &index)
| Drop one attribute from the VDB tree (convenience method).
template<typename PointDataTreeT>
void | dropAttribute (PointDataTreeT &tree, const Name &name)
| Drop one attribute from the VDB tree (convenience method).
template<typename PointDataTreeT>
void | renameAttributes (PointDataTreeT &tree, const std::vector< Name > &oldNames, const std::vector< Name > &newNames)
| Rename attributes in a VDB tree.
template<typename PointDataTreeT>
void | renameAttribute (PointDataTreeT &tree, const Name &oldName, const Name &newName)
| Rename an attribute in a VDB tree.
