Syntax

object.SETSTATICtypeFIELD("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.

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 value.

Details

Once you instantiate a java object, you can access and modify its public fields through method calls on the java object. The SETSTATICtypeFIELD method enables you to modify static fields.

Note: type 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. [cautionend]

Comparisons

The SETSTATICtypeFIELD method modifies the value of a static field for a java object. To modify the value of a non-static field, use the SETtypeFIELD method.

Example

The following example creates a simple class that contains three static fields. The java object j is instantiated, the field values are set by using the SETSTATICtypeFIELD method and then retrieved.

/* Java code */
import java.util.*;
import java.lang.*;
public class ttestc
{
   public static double d;
   public static double dm()
   {
      return d;
   }
}

/* DATA step code */
data x;
   declare javaobj j("ttestc");
   length d 8;

   j.callSetStaticDoubleField("d", 3.14159);
   j.callStaticDoubleMethod("dm", d);
   put d=;
run;

The following line is written to the SAS log:

d=3.14159
