• Curly brackets indicate selection of clause that is delimited by ”| ”.

• Italic type indicates a variable character string.

Class class-name/interface-name

Specification format

Class

class-name/interface-name

[ =

constructor/method/field-specifying-

option

]

Specification contents

Specify the Java class name or interface name that generates an adapter class.

Also specify constructor/method/field specifying options when

constructor/method/fields are generated as an adapter class, for that

class-

name/interface-name

.

Meaning of the parameter

•

class-name/interface-name

Specifies a class name or interface name that is qualified by the package name.

When specifying an internal class name as the parameter type, specify dollar ($)

instead of period (.) of the internal class.

•

constructor/method/field-specifying-option

Specify a constructor/method/field using the format of -gc option, -gm option

and -gf option of the java2cob command.

The

constructor/method/field-specifying-option

is valid when the "Option

GenOnlyUsed" parameter specifies YES.

If

constructor/method/field-specifying-option

is not specified even though the

"Option GenOnlyUsed" parameter specifies YES, an adapter class without

constructor/method/field is generated.

Option ClassPath

Specification format

Option ClassPath =

class-path

Specification contents

Specify a search path of the Java class/interface. When specifying two or more

folders, delimit the folders using semi-colon (;).

When a blank is included in the class path, enclose the entire class path with double

quotation (").

When this option is specified, the environment variable CLASSPATH is ignored.
