Constructor Details

TarXzCompressedBinaryManager

public TarXzCompressedBinaryManager(@NonNull
 NativeBinaryLocator nativeBinaryLocator)

Creates a new binary manager for tar-xz compressed archives.

The implementation of NativeBinaryLocator to locate the stream that gets unpacked must satisfy the following criteria:

• It must override Object.equals(Object) and Object.hashCode().
• It should implement Object.toString() to return meaningful information about the locator.
• It must allow multiple calls to NativeBinaryLocator.getInputStream() which all return the same, byte-identical contents. The operation should be cheap as it may be called multiple times.

Parameters:

nativeBinaryLocator - An implementation of NativeBinaryLocator that satisfies the conditions above. Must not be null.

Method Details

setInstallationBaseDirectory

public void setInstallationBaseDirectory(File installationBaseDirectory)

Description copied from interface: NativeBinaryManager

Sets the installation directory. This method must be called before the first call to NativeBinaryManager.getLocation().

Implementing this method is optional if no local installation directory is required.

Specified by:

setInstallationBaseDirectory in interface NativeBinaryManager

Parameters:

installationBaseDirectory - Base directory in which the binary distribution is unpacked. Must not be null.

setLockFileName

public void setLockFileName(String lockFileName)

Sets the lock file name. This method must be called before the first call to getLocation().

Parameters:

lockFileName - Name of a file to use as file lock when unpacking the distribution.

getLocation

@NonNull
public File getLocation()
                 throws IOException

Description copied from interface: NativeBinaryManager

Returns the location (installation directory) for the installed binary.

Specified by:

getLocation in interface NativeBinaryManager

Returns:

Installation directory with the native binary installed.

Throws:

IOException - If the binary could not be located or installed.
