Syntax

object.CALLSTATICtypeMETHOD ("method-name", <method-argument-1 ..., method-argument-n>, <return value>);

Arguments

object

specifies the name of the java object.

type

specifies the result type for the static Java method. The type can be one of the following values:

BOOLEAN: specifies that the result type is BOOLEAN.
BYTE: specifies that the result type is BYTE.
CHAR: specifies that the result type is CHAR.
DOUBLE: specifies that the result type is DOUBLE.
FLOAT: specifies that the result type is FLOAT.
INT: specifies that the result type is INT.
LONG: specifies that the result type is LONG.
SHORT: specifies that the result type is SHORT.
STRING: specifies that the result type is STRING.
VOID: specifies that the result type is VOID.

Type Issues in SAS Language Reference: Concepts

method-name

specifies the name of the static Java method.

Requirement:

The method name must be enclosed in either single or double quotation marks.

method-argument

specifies the parameters to pass to the method.

return-value

specifies the return value if the method returns one.

Details

Once you instantiate a java object, you can access any static Java method through method calls on the java object by using the CALLSTATICtypeMETHOD method.

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

Use the CALLSTATICtypeMETHOD method for static Java methods. If the Java method is not static, use the CALLtypeMETHOD 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 and then retrieved by using the CALLSTATICtypeFIELD method.

/* 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.SetStaticDoubleField("d", 3.14159);
   j.callStaticDoubleMethod("dm", d);
   put d=;
run;

The following line is written to the SAS log:

d=3.14159
