Constructor Detail

LicenseWriter

public LicenseWriter()

Creates a new instance of the LicenseWriter

Method Detail

createLicenseWriter

public static LicenseWriter createLicenseWriter()

Creates a new instance of the LicenseWriter

Returns:

a new instance of the LicenseWriter

getEncryptKeyBytes

public byte[] getEncryptKeyBytes()

Returns bytes array that specifies key used to encrypt the license.

Returns:

key bytes

setEncryptKeyBytes

public void setEncryptKeyBytes(byte[] aEncryptKeyBytes)

Specifies bytes array that represents key used to encrypt the license.

Parameters:

aEncryptKeyBytes - key bytes

getPublicKeyBytes

public byte[] getPublicKeyBytes()

Deprecated. use getEncryptKeyBytes() instead

Returns bytes array that specifies public key used to encode the license.

Returns:

public key bytes

setPublicKeyBytes

public void setPublicKeyBytes(byte[] aPublicKeyBytes)

Deprecated. use setEncryptKeyBytes(...) instead

Specifies bytes array that represents public key used to encode the license.

Parameters:

aPublicKeyBytes - public key bytes

isSkipEncryption

public boolean isSkipEncryption()

Checks whether license encryption should be skipped.

Returns:

true license encryption should be skipped, false otherwise.

setSkipEncryption

public void setSkipEncryption(boolean aSkipEncryption)

Specifies that license encryption should be skipped. Note: skipping can be useful for debugging purposes only.

Parameters:

aSkipEncryption - true if license encryption should be skipped, false otherwise.

isVerbose

public boolean isVerbose()

Checks whether writer runs in verbose mode.

Returns:

true if writer runs in verbose mode, false otherwise.

setVerbose

public void setVerbose(boolean aVerbose)

Specifies that writer should run in verbose mode. If writer run in verbose mode all thrown exceptions and stack traces will be printed out to the stderr. Otherwise there is no output generated in order to prevent the "code flow" analysis.

Parameters:

aVerbose - true if writer should run in verbose mode, false otherwise.

writeLicense

public void writeLicense(License aLicense,
                         java.io.OutputStream anOutputStream)
                  throws java.io.IOException

Encodes and writes license to the specified stream

Parameters:

aLicense - license to encode and write

anOutputStream - stream to write license to

Throws:

java.io.IOException - in case of writing error

writeLicense

public void writeLicense(License aLicense,
                         java.io.File aFile)
                  throws java.io.IOException

Encodes and writes license to the specified file

Parameters:

aLicense - license to encode and write

aFile - file to write license to

Throws:

java.io.IOException - in case of writing error

reset

public static void reset()

release

public static void release()

Releases all the static resources acquired by License Writer's

checkLicense

public static void checkLicense(boolean aForceLicenseRead)
