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

Category:	Method reference
Applies to:	Java object

Syntax

object.CALLtypeMETHOD ("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 non-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 non-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 non-static Java method through method calls on the Java object by using the CALLtypeMETHOD 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 CALLtypeMETHOD method for non-static Java methods. If the Java method is static, use the CALLSTATICtypeMETHOD method.

Example: Setting and Retrieving Field Values

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 set and retrieved using the CALLtypeFIELD method.

/* Java code */
import java.util.*;
import java.lang.*;
public class ttest
{
   public int i;
   public double d;
   public string s;
   public int im()
   {
      return i;
   }
   public String sm()
   {
       return s;
   }
   public double dm()
   {
      return d;
   }
}

/*  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.callIntMethod("im", val);
   put val=;
   j.callDoubleMethod("dm", val);
   put val=;
   j.callStringMethod("sm", str);
   put str=;
run;

The following lines are written to the SAS log:

val=100
val=3.14159
str=abc
