Name
import_jar — Creates SQL wrapper types of selected Java classes
Synopsis
void import_jar ( |
in files any , |
in classes any , | |
in security_mode integer
) ; |
Description
This function calls the jvm_ref_import()
function to produce the XML,
then transforms it to a set of CREATE TYPE statements and executes
them. The SQL names of the types are generated by retrieving the
fully qualified name of the Java class and substituting the . with
_ (e.g.: java.lang.System becomes java_lang_System). The names of
the static members observer functions are composed by prepending
the name of the static member with 'get' so the static Java member
stat_m is mapped to a SQL static method getstat_m(). As a result it
creates SQL type wrappers for the specified Java classes.
Parameters
files
Null, string or vector of strings. This can contain one or many Java .class files, .zip or .jar files to pick classes from. Null means only the classes specified in the classes argument regardless of their physical location.
classes
Wildcard string or a vector of strings specifying which classes to describe in the resulting XML.
security_mode
This optional parameter defines the access mode as follows:
0 - restricted (default if unspecified) |
1 - unrestricted |
