Constructor Detail

SerialComPlatform

public SerialComPlatform(SerialComSystemProperty mSerialComSystemProperty)

Allocates a new SerialComPlatform object.

Parameters:

mSerialComSystemProperty - instance which gives various info about system properties

Method Detail

getOSType

public final int getOSType()
                    throws SecurityException,
                           SerialComUnexpectedException

Identifies the operating system on which scm library is running.

Returns:

SerialComManager.OS_UNKNOWN if platform is unknown to scm otherwise one of the SerialComManager.OS_XXXX constant.

Throws:

SecurityException - if java system properties can not be accessed.

SerialComUnexpectedException - if the "os.name" java system property is null.

getCPUArch

public final int getCPUArch(int osType)
                     throws SecurityException,
                            SerialComUnexpectedException,
                            FileNotFoundException,
                            IOException

Identifies CPU architecture scm library is running on.

Packages that are compiled for i386 architecture are compatible with i486, i586, i686, i786, i886 and i986 architectures. Packages that are compiled for x86_64 architecture are compatible with amd64 architecture.

Returns:

SerialComManager.ARCH_UNKNOWN if platform is unknown to SCM otherwise one of the SerialComManager.ARCH_XXXX constant.

Throws:

SecurityException - if java system properties can not be accessed.

SerialComUnexpectedException - if the "os.arch" java system property is null.

FileNotFoundException - if file "/proc/cpuinfo" can not be found for Linux on ARM platform.

IOException - if file operations on "/proc/cpuinfo" fails for Linux on ARM platform.

getJAVAABIType

public final int getJAVAABIType()
                         throws SerialComUnexpectedException

Conformance to the standard ABI for the ARM architecture helps in inter-operation between re-locatable or executable files built by different tool chains.

Returns:

either ABI_ARMHF or ABI_ARMEL constant value as per identification.

Throws:

SerialComUnexpectedException - if "java.home" java system property is null.
