| Wrapper minervax is used to extend MINERVA with external classes
and their methods.
External classes can be used by MINERVA just like built-in predicates.
External classes can be from some vendor's Java system, e.g. for
networking, imaging, multimedia etc, third party class libraries,
or written by yourself.
External classes can be added to MINERVA statically at boot time
or dynamically ("on demand") when first used during run time.
A java compiler is required to use minervax.
minervax is invoked as
minervax [-gui] [-c InterfaceClass] [-f MinervaFrame] [-p PackageName] DescriptionName
Parameters are:
- -gui
Indicates that the extension should include gui support
i.e. the new MinervaFrame will replace
com.ifcomputer.minerva.Gui
- -c InterfaceClass
Name of the interface class. Defaults to DescriptionName
- -f MinervaFrame
Name of the new top level class to be invoked by the script 'minerva'
Used if the extensions are added statically.
This class is then used to replace
com.ifcomputer.minerva.Application or
com.ifcomputer.minerva.Gui which are called by minerva resp.
minervagui.
- -p PackageName
Name for a Java package that shall contains the new predicates.
- DescriptionName
The file DescriptionName.mxt holds the interface specification
that maps methods to MINERVA predicates.
Defaults to 'MinervaExtension'.
The file names must not include the extension.
Minervax will append the extension
- .mpk to the package declaration file
- .java to the frame and interface files
- .mxt to the interface description file
Please refer to the Example Programs for usage example.
Note that the reflection package provides an alternative way
to extend MINERVA with existing Java-based software components.
