Constructor Detail

LTMTopicMapWriter

public LTMTopicMapWriter(java.io.OutputStream stream)
                  throws java.io.IOException

PUBLIC: Create an LTMTopicMapWriter that writes to a given OutputStream in UTF-8. Warning: Use of this method is discouraged, as it is very easy to get character encoding errors with this method.

Parameters:

stream - Where the output should be written.

Throws:

java.io.IOException

LTMTopicMapWriter

public LTMTopicMapWriter(java.io.OutputStream stream,
                         java.lang.String encoding)
                  throws java.io.IOException

PUBLIC: Create an LTMTopicMapWriter that writes to a given OutputStream in the given encoding.

Parameters:

stream - Where the output should be written.

encoding - The desired character encoding.

Throws:

java.io.IOException

LTMTopicMapWriter

public LTMTopicMapWriter(java.io.Writer out)

Deprecated.

PUBLIC: Create an LTMTopicMapWriter that writes to a given Writer.

Parameters:

out - Where the output should be written.

LTMTopicMapWriter

public LTMTopicMapWriter(java.io.Writer out,
                         java.lang.String encoding)

PUBLIC: Create an LTMTopicMapWriter that writes to a given Writer.

Parameters:

out - Where the output should be written.

encoding - The encoding used by the writer. This is the encoding that will be declared on the first line of the LTM file. It must be reported, because there is no way for the LTMTopicMapWriter to know what encoding the writer uses.

Since:

4.0

Method Detail

setPreserveIds

public void setPreserveIds(boolean preserveIds)

PUBLIC: Set whether IDs should be preserved or generated.

Parameters:

preserveIds - Should be set to true if IDs should be preserved.

setFilter

public void setFilter(DeciderIF filter)

PUBLIC: Sets the filter that decides which topic map constructs are accepted in the exprted ltm. Uses 'filter' to identify individual topic constructs as allowed or disallowed. TM constructs that depend on the disallowed topics are also disallowed.

Parameters:

filter - Places constraints on individual topicmap constructs.

write

public void write(TopicMapIF tm)
           throws java.io.IOException

PUBLIC: Writes out the given topic map.

Specified by:

write in interface TopicMapWriterIF

Parameters:

tm - The topic map to be exported/written; an object implementing TopicMapIF

Throws:

java.io.IOException - Thrown if writing the topic map fails.
