Method Detail

protected abstract boolean matches()

Creates a NativePlatform. This is only called if matches() was previously called and returned true.

Returns:

a new NativePlatform.

getMajorVersion

protected abstract int getMajorVersion()

Queries the major version number supported by this NativePlatformFactory.

Returns:

the major version supported

protected abstract int getMinorVersion()

Queries the minor version number supported by this NativePlatformFactory.

getNativePlatform

public static NativePlatform getNativePlatform()

Obtains a NativePlatform that matches the platform on which we are running. The system property monocle.platform defines a series of cascading fallbacks for what NativePlatform types to attempt to create. monocle .platform can be overridden to select a specific platform. For example, running with -Dmonocle.platform=Dispman, Linux selects the NativePlatform that works with the dispmanx libraries on the Raspberry Pi, but falls back to a generic software-rendered Linux framebuffer implementation if we are not running on a device with dispmanx libraries.

Returns:

a new NativePlatform
