Field Detail

columns

public Parameter columns

The columns to write. This is an array of strings specifying the column names to write, and the order in which they are written. It defaults to ALL, which indicates that all fields should be written. In this case, the columns are organized alphabetically.

records

public Parameter records

Parameter to store the array of records read at the input. This is an array of records that is by default empty.

Constructor Detail

ArrayOfRecordsExporter

public ArrayOfRecordsExporter(CompositeEntity container,
                              java.lang.String name)
                       throws NameDuplicationException,
                              IllegalActionException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the entity cannot be contained by the proposed container.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

_setInputConstraints

protected void _setInputConstraints()
                             throws IllegalActionException

Set the type constraints and multiport property of the input port. This is done here so that derived classes can override it.

Overrides:

_setInputConstraints in class LineWriter

Throws:

IllegalActionException - If making the port a multiport is not allowed.

_writeToken

protected void _writeToken(Token token)
                    throws IllegalActionException

Write the specified token to the current writer. This is protected so that derived classes can modify the format in which the token is written.

Overrides:

_writeToken in class LineWriter

Parameters:

token - The token to write.

Throws:

IllegalActionException - If the input token cannot be read.
