Get the reader.

rasterFile

public java.io.File rasterFile()

Get the file.

getType

public Type getType()

Description copied from class: Token

Return the type of this token.

Overrides:

getType in class Token

Returns:

BaseType.GENERAL

isEqualTo

public final BooleanToken isEqualTo(Token rightArgument)
                             throws IllegalActionException

Test for equality of the values of this Token and the argument Token. If the value of this token or the value of the rightArgument token is null, then we return False.

Overrides:

isEqualTo in class Token

Parameters:

rightArgument - The Token to test against.

Returns:

A boolean token that contains the value true if the dates are the same.

Throws:

IllegalActionException - Not thrown in this base class.

toString

public java.lang.String toString()

Return a String representation of the DateToken. The string is surrounded by double-quotes; without them, the Ptolemy expression parser fails to parse it.

Overrides:

toString in class Token

Returns:

A String representation of the DateToken.
