jvm: Auxiliary functions to get information on JVM.

In PolMine/bignlp: Fast and Memory-Efficient Annotation of Big Corpora

Description

Upon loading the bignlp package, a Java Virtual Machine (JVM) is initialized. Some auxiliary functions provide information on the configuration of the JVM and its status. Use the functions to check which Java is installed (recommended: Oracle Java), the Java version and the heap space of the JVM.

Usage

jvm_is_initialized()

jvm_name()

jvm_version()

jvm_heap_space(units = "MB")

jvm_memory_usage()

jvm_available_processors()

Arguments

units

See documentation of format.object_size, typically either "MB" or "GB".

Details

jvm_is_initialized checks whether a JVM has been initialized already. The return value is a logical value, TRUE if JVM has been initialized, FALSE if not. As a JVM is initialized upon loading bignlp, the expected value is always TRUE if your installation of Java and rJave works.

Examples

jvm_is_initialized()
jvm_name()
jvm_version()
jvm_heap_space()
jvm_memory_usage()
