Field Detail

typeMap

private static java.util.Map<java.lang.String,java.lang.Integer> typeMap

Member used to map string values returned by the `: type [varname]' extended macro function to integer values used in the .dta specification to represent the data types.

typeClassMap

private static java.util.Map<java.lang.String,java.lang.String> typeClassMap

Member used to store the class types of the data so the values can be recast using reflection methods

Constructor Detail

StataTypes

StataTypes()

Class constructor for the StataTypes class. The class calls the setMap() method to build the typeMap object and nothing else.

Method Detail

getType

public static java.lang.Integer getType(java.lang.String type)

Method to translate a value from `: type [varname]' into an integer value corresponding to the data type based on the .dta file specification.

Parameters:

type - A string returned from the `: type ' extended macro function (e.g., byte, int, long, float, double, str#, strL)

Returns:

An integer corresponding to the variable type mapping listed in the .dta file specification.

getClassType

public static java.lang.String getClassType(java.lang.String type)

Like the getType method of this class, this method is used to look up variable type definitions for a valued retrieved from `: type [varnm]' . The difference between the methods is that this method returns the class name string of the Java type that would represent the data correctly.

Parameters:

type - A string returned from the `: type ' extended macro function (e.g., byte, int, long, float, double, str#, strL)

Returns:

A fully specified Java class name (e.g., java.lang.String) that can be used to dynamically case the data using reflections.

setMaps

private static void setMaps()

Method used to construct the Map object used to look up values and return the appropriate type integer
