Example

Syntax

object.GETtypeFIELD("field-name", value);

Arguments

object: specifies the name of a Java object.

type

specifies the type for the Java field. The type can be one of the following values:

BOOLEAN: specifies that the field type is BOOLEAN.

BYTE: specifies that the field type is BYTE.

CHAR: specifies that the field type is CHAR.

DOUBLE: specifies that the field type is DOUBLE.

FLOAT: specifies that the field type is FLOAT.

INT: specifies that the field type is INT.

LONG: specifies that the field type is LONG.

SHORT: specifies that the field type is SHORT.

STRING: specifies that the field type is STRING.

See:Type Issues in SAS Language Reference: Concepts

field-name: specifies the Java field name.

Requirement:The field name must be enclosed in either single or double quotation marks.

value: specifies the name of the variable that receives the returned field value.

Details

Once you instantiate a Java object, you can access and modify its public fields through method calls on the Java object. The GETtypeFIELD method enables you to access non-static fields.

Note: The type argument represents a Java data type. For more information about how Java data types relate to SAS data types, see Type Issues in SAS Language Reference: Concepts.

Comparisons

The GETtypeFIELD method returns the value of a non-static field for a Java object. To return the value of a static field, use the GETSTATICtypeFIELD method.

Example: Retrieving the Value of a Non-Static Field

The following example creates a simple class that contains three non-static fields. The Java object j is instantiated, and then the field values are modified and retrieved using the GETtypeFIELD method.

/* Java code */
import java.util.*;
import java.lang.*;
public class ttest
{
   public int i;
   public double d;
   public string s;
}
}

/*  DATA step code */
data _null_;
   dcl javaobj j("ttest");
   length val 8;
   length str $20;
   j.setIntField("i", 100);
   j.setDoubleField("d", 3.14159);
   j.setStringField("s", "abc");
   j.getIntField("i", val);
   put val=;
   j.getDoubleField("d", val);
   put val=;
   j.getStringField("s", str);
   put str=;
run;

The following lines are written to the SAS log:

val=100
val=3.14159
str=abc
