FieldInfo

Runtime reflection utility for extracting field type information from classes.

This class provides a way to retrieve type information about fields at runtime, which is normally lost due to Haxe's type erasure. It works with Entity subclasses marked with @fieldInfo or @autoFieldInfo metadata, or any class processed by the FieldInfoMacro build macro.

The field information is extracted from a special _fieldInfo static field that is generated at compile time by the FieldInfoMacro. This allows for runtime introspection of field types, which is useful for serialization, binding systems, and dynamic property manipulation.

Static Members #

Retrieves a map of field names to their type information for a given class.

This method extracts field type information that was generated at compile time by the FieldInfoMacro. The information is cached after the first retrieval for performance.

Example:

var types = FieldInfo.types("myapp.Player");
trace(types.get("health")); // "Float"
trace(types.get("name")); // "String"

Gets the type information for a specific field of a class.

This is a convenience method that retrieves the type of a single field without having to access the full types map.

Example:

var healthType = FieldInfo.typeOf("myapp.Player", "health");
trace(healthType); // "Float"
