Specified by:

setEscapeTable in interface TupleWriter

Parameters:

escapeTable - the table

getEscapeTable

public Hashtable<Character,String> getEscapeTable()

Description copied from interface: TupleWriter

This method returns the current escape table for this TupleWriter

Specified by:

getEscapeTable in interface TupleWriter

Returns:

the current escape table

getEncoding

public String getEncoding()

Description copied from interface: TupleWriter

Returns the encoding in which data shall be stored.

Specified by:

getEncoding in interface TupleWriter

Returns:

encoding in which data shall be stored

setFile

public void setFile(File out)

Description copied from interface: TupleWriter

Sets the output file to the given.

Specified by:

setFile in interface TupleWriter

getFile

public File getFile()

Description copied from interface: TupleWriter

Returns the output file.

Specified by:

getFile in interface TupleWriter

Returns:

the output file

setAttNames

public void setAttNames(Collection<String> attNames)

Description copied from interface: TupleWriter

Sets the names of attributes to which data belong.

Specified by:

setAttNames in interface TupleWriter

Parameters:

attNames - - names of attributes to which data belong

getAttNames

public Collection<String> getAttNames()

Description copied from interface: TupleWriter

Specified by:

getAttNames in interface TupleWriter

Returns:

attNames - names of attributes to which data belong

setSeperator

public void setSeperator(String seperator)

Description copied from interface: TupleWriter

Sets the seperator with which the data will be departed on stream. Default seperator is tab.

Specified by:

setSeperator in interface TupleWriter

Parameters:

seperator - with which the data will be departed on stream

getSeperator

public String getSeperator()

Description copied from interface: TupleWriter

Returns the seperator with which the data will be departed on stream.

Specified by:

getSeperator in interface TupleWriter

Returns:

seperator with which the data will be departed on stream

finalize

public void finalize()

Overrides:

finalize in class Object

isDistinct

public Boolean isDistinct()

Description copied from interface: TupleWriter

Returns true if this tuple writer stores values more than one times, if they are equal

Specified by:

isDistinct in interface TupleWriter

Returns:

true, if tuples were stored distinct, default value is false.

setDistinct

public void setDistinct(Boolean distinct)

Description copied from interface: TupleWriter

Set the distinct value for this tuple writer. If distinct= true, no duplicates will be stored for the same transaction. duplicates means two or more tuples with the same entries. To compare two tuples, the equals method of the string value is used (case sensitive). Default value is false. Attetntion: setting distinct to true makes add(...) very expensive

Specified by:

setDistinct in interface TupleWriter

Parameters:

distinct - true if values shall be stored distinct.
