CALLSTATICtypeMETHOD Method

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

Category:	Method Reference
Applies to:	Java object

Syntax

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
