PlatformDetector

public PlatformDetector()

Method Detail

setOs

public void setOs(java.lang.String aOs)

Override the operating system name. This should only be used in test cases.

Parameters:

aOs - an OS name as could be found in the os.name system property.

getOs

public java.lang.String getOs()

Get the operating system.

Returns:

"windows", "osx", "linux" or "solaris".

setArch

public void setArch(java.lang.String aArch)

Override the architecture. This should only be used in test cases.

Parameters:

aArch - "big-endian" for PowerPC or Sparc systems or "little-endian" for x86 systems.

getArch

public java.lang.String getArch()

Get the platform architecture.

Returns:

"ppc", "x86_32", "x86_64" or {"amd64"}

setByteOrder

public void setByteOrder(java.nio.ByteOrder aByteOrder)

Set the byte order. TreeTagger models are sensitive to the byte order. This should only be used in test cases.

Parameters:

aByteOrder - the byte order.

getExecutableSuffix

public java.lang.String getExecutableSuffix()

Get the file suffix used for executable files on the currently configured platform.

Returns:

the file suffix used for executable files.

getByteOrder

public java.lang.String getByteOrder()

Get the byte order.

Returns:

the byte order.

getPlatformId

public java.lang.String getPlatformId()

Get the platform ID which is getOs() and getArch() separated by a "-" (dash).

Returns:

the platform ID.

updatePlatform

public void updatePlatform(java.lang.String aOs,
                           java.lang.String aArch,
                           java.nio.ByteOrder aByteOrder)

Updates the platform-specific settings and normalizes them.

Parameters:

aOs - the operating system string.

aArch - the architecture string.

aByteOrder - the byte-order string.

getChmodCmd

public java.lang.String[] getChmodCmd()

Get the chmod (change permissions) command for the current platform (if one is necessary).

Returns:

the name of the chmod command.
