               java.lang.String majorVersionUnicode,
               java.lang.String minorVersionUnicode,
               java.lang.String releaseLevelUnicode,
               int[] tagList)

Constructs a new COM file.

Parameters:

versionLDS - a numerical string of length 2

updateLevelLDS - a numerical string of length 2

majorVersionUnicode - a numerical string of length 2

minorVersionUnicode - a numerical string of length 2

releaseLevelUnicode - a numerical string of length 2

tagList - a list of ICAO data group tags

Throws:

java.lang.IllegalArgumentException - if the input is not well-formed

COMFile

public COMFile(java.lang.String ldsVer,
               java.lang.String unicodeVer,
               int[] tagList)

Constructs a new COM file.

Parameters:

ldsVer - a "x.y" version number

unicodeVer - a "x.y.z" version number

tagList - list of tags

COMFile

public COMFile(java.io.InputStream in)
        throws java.io.IOException

Constructs a new EF_COM file based on the encoded value in in.

Parameters:

in - should contain a TLV object with appropriate tag and contents

Throws:

java.io.IOException - if the input could not be decoded

Method Detail

readContent

protected void readContent(java.io.InputStream in)
                    throws java.io.IOException

Description copied from class: DataGroup

Reads the contents of the data group from an input stream. Client code implementing this method should only read the contents from the input stream, not the tag or length of the data group.

Specified by:

readContent in class DataGroup

Parameters:

in - the input stream to read from

Throws:

java.io.IOException - on error reading from input stream

getLDSVersion

public java.lang.String getLDSVersion()

Gets the LDS version as a dot seperated string containing version and update level.

Returns:

a string of the form "a.b"

getUnicodeVersion

public java.lang.String getUnicodeVersion()

Gets the unicode version as a dot seperated string containing major version, minor version, and release level.

Returns:

a string of the form "aa.bb.cc"

getTagList

public int[] getTagList()

Gets the ICAO datagroup tags as a list of bytes.

Returns:

a list of bytes
