Constructor Detail

COMFile

public COMFile(String versionLDS,
               String updateLevelLDS,
               String majorVersionUnicode,
               String minorVersionUnicode,
               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:

IllegalArgumentException - if the input is not well-formed

COMFile

public COMFile(String ldsVer,
               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(InputStream in)
        throws 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:

IOException - if the input could not be decoded

Method Detail

readContent

protected void readContent(InputStream in)
                    throws IOException

Description copied from class: AbstractTaggedLDSFile

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 AbstractTaggedLDSFile

Parameters:

in - the input stream to read from

Throws:

IOException - on error reading from input stream

getLDSVersion

public String getLDSVersion()

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

Returns:

a string of the form "a.b"

getUnicodeVersion

public String getUnicodeVersion()

Returns 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()

Returns the ICAO datagroup tags as a list of bytes.

Returns:

a list of bytes

insertTag

public void insertTag(Integer tag)

Inserts a tag in a proper place if not already present.

Parameters:

tag - the tag to insert

writeContent

protected void writeContent(OutputStream out)
                     throws IOException

Description copied from class: AbstractTaggedLDSFile

Writes the contents of the data group to an output stream. Client code implementing this method should only write the contents to the output stream, not the tag or length of the data group.

Specified by:

writeContent in class AbstractTaggedLDSFile

Parameters:

out - the output stream to write to

Throws:

IOException - on error writing to output stream

toString

Overrides:

toString in class AbstractTaggedLDSFile

Returns:

a textual representation of this file

equals

public boolean equals(Object other)

Whether other is equal to this file.

Overrides:

equals in class Object

Returns:

a boolean

hashCode

public int hashCode()

Overrides:

hashCode in class Object
