Java Meta Type

array()#

array(name, init) - Return a new Java array of given Java type (type name or type object) and initializer (array length or sequence). Possible primitive types are ‘boolean’, ‘byte’, ‘char’, ‘short’, ‘int’, ‘long’, ‘float’, and ‘double’.

create_jvm()#

create_jvm(options) - Create the Java VM from the given list of options.

destroy_jvm()#

destroy_jvm() - Destroy the current Java VM.

get_type()#

get_type(name, resolve=True) - Return the Java class with the given name, e.g. ‘java.io.File’. Loads the Java class from the JVM if not already done. Optionally avoids resolving the class’ methods.

has_jvm()#

has_jvm() - Check if the JVM is available.
