Constructor Detail

XTCEDatabase

public XTCEDatabase(URL dbLocation,
                    boolean validateOnLoad,
                    boolean applyXIncludes,
                    boolean readOnly)
             throws XTCEDatabaseException

Constructor for use with an XTCE database file on the filesystem. Successfully constructing this object means that the XTCE database file was successfully loaded and methods can be called on the contents.

Parameters:

dbLocation - URL object containing the location of the XTCE document to load.

validateOnLoad - boolean indicating if the XSD validation should be performed during the loading.

applyXIncludes - boolean indicating if the XInclude processing for the loaded file should be applied or ignored.

readOnly - boolean indicating if the document should be opened in a read-only context, which is faster because only the JAXB structure is created, avoiding the need to build the Document Object Model that is needed for round trip processing.

Throws:

XTCEDatabaseException - in the event that the file could not be successfully loaded in a valid state. This can be partly bypassed by not enabling the XSD validation, which is not recommended because it may de-stabilize the application using this data file.

Throws:

XTCEDatabaseException - in the event that the file could not be successfully loaded in a valid state. This can be partly bypassed by not enabling the XSD validation, which is not recommended because it may de-stabilize the application using this data file.

                                               throws XTCEDatabaseException

Function to decompose an XTCETelecommand object into a simple array of entries that an application can iterate over without the need to resolve XTCE data model references, included additional containers, base containers, and conditional processing. This function is intended to accept the byte array that is read from a ByteArrayOutputStream.toByteArray() that is easily obtained when reading a binary file using a Java FileInputStream.

Parameters:

telecommand - XTCETelecommand object containing the telecommand that the caller wishes to decompose.

bytes - byte[] containing the container binary encoded data so that the output object contains entries with actual values from a real binary image.

Returns:

XTCETelecommandContentModel representing this XTCETelecommand.

Throws:

XTCEDatabaseException - thrown in the event that it is not possible to decompose the container completely due to bad references in the XTCE document.

processTelecommand

public XTCETelecommandContentModel processTelecommand(XTCETelecommand telecommand,
                                                      InputStream stream)
                                               throws XTCEDatabaseException

Function to decompose an XTCETelecommand object into a simple array of entries that an application can iterate over without the need to resolve XTCE data model references, included additional containers, base containers, and conditional processing. This function is intended to accept a Java InputStream containing the bytes to use for the binary portion of the container.

Parameters:

telecommand - XTCETelecommand object containing the telecommand that the caller wishes to decompose.

stream - InputStream containing the container binary encoded data so that the output object contains entries with actual values from a real binary image.

Returns:

XTCETelecommandContentModel representing this XTCETelecommand.

Throws:

XTCEDatabaseException - thrown in the event that it is not possible to decompose the container completely due to bad references in the XTCE document, or if the stream throws an IOException.

findContainers

public List<XTCETMContainer> findContainers(XTCEParameter parameter)

Retrieve the containers in the XTCE document that directly reference an entry in their manifest that includes the provided Parameter.

Parameters:

parameter - XTCEParameter object to find in the containers defined in this XTCE database document.

Returns:

List of XTCETMContainer objects found, or an empty list if the no container references the parameter.

getParameterTypeReference

public org.omg.space.xtce.NameDescriptionType getParameterTypeReference(String typePath)

Retrieve the type reference from the JAXB generated objects for a particular TM Parameter fully qualified type object path in the XTCE data model.

Parameters:

typePath - String containing the UNIX style fully qualified path to the TM Parameter type object.

Returns:

NameDescriptionType base class for the type object found, or a null object reference in the event that it is not found.

getArgumentTypeReference

public org.omg.space.xtce.NameDescriptionType getArgumentTypeReference(String typePath)

Retrieve the type reference from the JAXB generated objects for a particular TC Argument fully qualified type object path in the XTCE data model.

Parameters:

typePath - String containing the UNIX style fully qualified path to the TC Argument type object.

Returns:

NameDescriptionType base class for the type object found, or a null object reference in the event that it is not found.
