The target can be either a directory in which the header files will be written, or a header file name which will contain all of the definitions. The source can be the names of <filename>.class</filename> files, the names of <filename>.java</filename> files to be compiled into <filename>.class</filename> files by calling the &b-link-Java; builder method, or the objects returned from the &b-Java; builder method. If the construction variable &cv-link-JAVACLASSDIR; is set, either in the environment or in the call to the &b-JavaH; builder method itself, then the value of the variable will be stripped from the beginning of any <filename>.class</filename> file names. Examples: <example> # builds java_native.h classes = env.Java(target = 'classdir', source = 'src') env.JavaH(target = 'java_native.h', source = classes) # builds include/package_foo.h and include/package_bar.h env.JavaH(target = 'include', source = ['package/foo.class', 'package/bar.class']) # builds export/foo.h and export/bar.h env.JavaH(target = 'export', source = ['classes/foo.class', 'classes/bar.class'], JAVACLASSDIR = 'classes') </example> </summary> </builder> <cvar name="JAVAH"> <summary> The Java generator for C header and stub files. </summary> </cvar> <cvar name="JAVAHCOM"> <summary> The command line used to generate C header and stub files from Java classes. Any options specified in the &cv-link-JAVAHFLAGS; construction variable are included on this command line. </summary> </cvar> <cvar name="JAVAHCOMSTR"> <summary> The string displayed when C header and stub files are generated from Java classes. If this is not set, then &cv-link-JAVAHCOM; (the command line) is displayed. <example> env = Environment(JAVAHCOMSTR = "Generating header/stub file(s) $TARGETS from $SOURCES") </example> </summary> </cvar> <cvar name="JAVAHFLAGS"> <summary> General options passed to the C header and stub file generator for Java classes. </summary> </cvar>
