Detailed Description
Node is the building block for parse trees.
Each node represents an avro type. Compound types have leaf nodes that represent the types they are composed of.
The user does not use the Node object directly, they interface with Schema objects.
The Node object uses reference-counted pointers. This is so that schemas may be reused in other other schemas, without needing to worry about memory deallocation for nodes that are added to multiple schema parse trees.
Node has minimal implementation, serving as an abstract base class for different node types.
The documentation for this class was generated from the following file:
