public class Destination

extends java.io.File

This class represents the destination of the output of one of the tools included in the project. If a destination is specified on the command line and the input belongs to a package then the output should be written to the concatenation of the destination directory and the package names. If no destination is specified then the output should be written to the same directory as the input. The destination parameter from the command line is used to construct an instance of this. That instance provides File objects (via the ...target() methods) for writing particular output files.

Field Summary
private  boolean	unspecified           Indicates whether the destination directory was unspecified on the command line.

Field Detail

unspecified

private boolean unspecified

Indicates whether the destination directory was unspecified on the command line.

Destination

private Destination(java.lang.String destination,
                    boolean unspecified)

check

public static Destination check(java.lang.String dest)

Establish a new destination based on the command line argument. If the argument is null then the destination is unspecified and will be the current working directory.

textTarget

public java.io.File textTarget(java.lang.String filename)

Returns the target for a text file, which is simply filename appended to the destination directory.

classFileTargetDirectory

public java.io.File classFileTargetDirectory(java.lang.String packageName,
                                             java.io.File sourceFile)

Returns the target directory for writing a class file of the given package and source file.

 ensures unspecified && sourceFile != null ==> \result == sourceFile;
 ensures unspecified && sourceFile == null ==> \result == this;
 ensures !unspecified ==> \result.equals( new File( this, packageName ));
