Invokes an instance method on a Java object from a static Java method.

Category:	Method reference
Applies to:	Java object

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.

See: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: 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

Use the CALLSTATICtypeMETHOD method for static Java methods. If the Java method is not static, use the CALLtypeMETHOD method.

Example: Setting and Retrieving Static Fields

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