Class semper.transfer.Security

java.lang.Object
   |
   +----semper.transfer.Security

public class Security

extends Object

implements Streamable

This class provides a wrapper for the security attributes of containers. The attributes are kept in a boolean array and the class provides different methods to get and set the elements of this array.

In the moment there are 6 different security attributes with indexes as follows:

• MESSAGE_CONFIDENTIALITY: 0
• MESSAGE_INTEGRITY: 1
• MESSAGE_AUTHENTICATION: 2
• ANONYMITY_BY_ALIAS: 3
• NON_REPUDIATON_OF_DELIVERY: 4
• NON_REPUDIATION_OF_RECEIPT: 5

ANONYMITY_BY_ALIAS

MESSAGE_AUTHENTICATION

MESSAGE_CONFIDENTIALITY

MESSAGE_INTEGRITY

NON_REPUDIATION_OF_RECEIPT

NON_REPUDIATON_OF_DELIVERY

SEC_ATTR_MAX

Security()

Simple default Constructor.

Security(boolean[])

Constructor with boolean array.

convert()

Converts this object into a SecurityOptions Vector of the payment block.

copy()

Clones a security object.

get(int)

Test the specified attribute.

getAll()

Gets an array with the boolean values of the attributes.

myStreamSize()

Gets the streamsize of the object.

readObject(StreamInputInterface)

Reads a security object from an input stream.

reset(int)

Resets the specified attribute (sets them to false).

resetAll()

Resets all security attributes (sets all to false).

set(int)

Sets the specified attribute.

setAll()

Sets all security attributes to true.

setMask(boolean[])

Sets the security attributes like the given boolean array.

writeObject(StreamOutputInterface)

Writes the object to an output stream.

  public Security()

Simple default Constructor. If this constructor is invoked all attributes are set to false.

  public Security(boolean SecAttributes[])

Constructor with boolean array. The corresponding attributes of array and object are set. If there are less than SEC_ATTR_MAX array elements only the first security attributes are set.

Parameters:

SecAttributes[] - describes the security attributes or features which are used

  public boolean[] getAll()

Gets an array with the boolean values of the attributes. In the returned array the indexes given by the class constants are set or not corresponding to the attributes in the security object.

Returns:

an array describing the security attributes or features which are used

  public boolean get(int i)

Test the specified attribute. If the specified index is higher than SEC_ATTR_MAX false is returned

Returns:

the boolean value of a security attributes or features (true if it's set).

  public void setMask(boolean SecAttributes[])

Sets the security attributes like the given boolean array. If there are less elements then security attributes, only the first security attributes are concerned

Parameters:

SecAttributes[] - describes the security attributes or features which are used

  public void setAll()

Sets all security attributes to true.

  public void set(int i)

Sets the specified attribute.

Parameters:

i - the index of the attribute to be set

  public void resetAll()

Resets all security attributes (sets all to false).

  public void reset(int i)

Resets the specified attribute (sets them to false).

  public void writeObject(StreamOutputInterface stream) throws StreamIOException

Writes the object to an output stream. This method writes the data content of the object into a stream which can later be read by the read method.

Parameters:

stream - the stream of data the object state is recorded in

Throws: StreamIOException

If a subobject does not implement the Streamable interface.

See Also:

StreamOutputInterface, TargetStream

  public void readObject(StreamInputInterface stream) throws StreamIOException

Reads a security object from an input stream. Parameter StreamInputInterface

Parameters:

stream - the stream of data the object state is retrieved from

Throws: StreamIOException

If a class is not present or the input data is corrupt

See Also:

StreamInputInterface, SourceStream

  public int myStreamSize()

Gets the streamsize of the object.

Returns:

the size of the stream

  public Security copy()

Clones a security object.

Returns:

a identical Object of the Class Security

  public Vector convert()

Converts this object into a SecurityOptions Vector of the payment block. The Options of the payment block do not fully correspondend with the security attributes.

Returns:

a Vector with the Options of the payment block
