Class DataTypeInstance

java.lang.Object

ghidra.program.model.data.DataTypeInstance

public class DataTypeInstance
extends java.lang.Object

An instance of a DataType that is applicable for a given context. Most dataTypes are not context sensitive and are suitable for use anywhere. Others like dynamic structures need to create an instance that wraps the data type. It helps for situations where a data type must have a length.
