jnew {rJava}R Documentation

Create a Java object

Description

.jnew create a new Java object

Usage

.jnew(class, ..., check=TRUE, silent=!check)

Arguments

class fully qualified class name in JNI notation (e.g. "java/lang/String").
... Any parametes that will be passed to the corresponding constructor. The parameter types are determined automatically and/or taken from the jobjRef object. For details see .jcall. Note that all named parameters are discarded.
check If set to TRUE then .jcheck is invoked before and after the call to the constructor to clear any pending Java exceptions.
silent If set to FALSE then .jnew will fail with an error if the object cannot be created, otherwise a null-reference is returned instead. In addition, this flag is also passed to final .jcheck if check above is set to TRUE. Note that the error handling also clears exceptions, so check=FALSE, silent=FALSE is usually not a meaningful combination.

Value

Returns the reference (jobjRef) to the newly created object or null-reference (see .jnull) if something went wrong.
