# Class StructureMappingInfo<T>

java.lang.Object
ghidra.app.util.bin.format.golang.structmapping.StructureMappingInfo<T>

Type Parameters:
  `T` - the class that is being mapped into a structure

public class StructureMappingInfo<T> extends Object

- ## Method Details

  - ### fromClass

    public static <T> StructureMappingInfo<T> fromClass(Class<T> targetClass, Structure structDataType, DataTypeMapperContext context)
    Returns the mapping info for a class, using annotations found in that class.
    Type Parameters:
      `T` - structure mapped class
    Parameters:
      `targetClass` - structure mapped class
      `structDataType` - Ghidra `DataType` that defines the binary layout of the mapped fields of the class, or null if this is a self-reading `StructureReader` class
      `context` - `DataTypeMapperContext`
    Returns:
      new `StructureMappingInfo` for the specified class
    Throws:
      `IllegalArgumentException` - if targetClass isn't tagged as a structure mapped class
