removeJavaConverter: Removes a converter for R and Java objects in the R-Java...

Description Usage Arguments Value Author(s) References See Also Examples

Description

This manipulates the internal list of object converters that control how objects are transferred from R to Java and from Java to R. It allows the R user to remove entries and control how objects are converted.

Usage

1
removeJavaConverter(id, fromJava=TRUE)

Arguments

id

the index or position of the converter to be removed in the specified converter list.

fromJava

logical value indicating which set of converters on which we are operating: from Java to R (TRUE) or from R to Java (FALSE). The latter is currently not implemented and awaits the next version which will use C++.

Value

Returns a integer identifying the position in the list in which the converter was located. This is a named vector and the name is the description of the converter. This allows one to ensure that you got the correct one.
