Class DataTypeInstance
java.lang.Object
ghidra.program.model.data.DataTypeInstance
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.
