fileName - The name of the file to which this JCompUnit will be written.

JCompUnit

public JCompUnit(JClass jClass)

Creates a new JCompUnit with the given JClass (which must have been created with either a full class name or package/local name) as the public class. Package and file name are taken from jClass.

Parameters:

jClass - The public class for this JCompUnit.

JCompUnit

public JCompUnit(JInterface jInterface)

Creates a new JCompUnit with the given JInterface as public interface. Package and file name are taken from jInterface.

Parameters:

jInterface - The public interface for this JCompUnit.

Method Detail

setHeader

public void setHeader(JComment comment)

Sets the header comment for this JCompUnit.

Parameters:

comment - The comment to display at the top of the source file when printed.

addStructure

public void addStructure(JStructure jStructure)

Adds the given JStructure (either a JInterface or a JClass) to this JCompUnit.

Parameters:

jStructure - The JStructure to add.

addClass

public void addClass(JClass jClass)

Adds a JClass to be printed in this file.

Parameters:

jClass - The JClass to be printed in this file.

addInterface

public void addInterface(JInterface jInterface)

Adds a JInterface to be printed in this file.

Parameters:

jInterface - The JInterface to be printed in this file.

getImports

public SortedSet<String> getImports()

Returns a array of String containing all imported classes/packages, also imports within the same package of this object.

Returns:

A array of String containing all import classes/packages, also imports within the same package of this object.

getFilename

public String getFilename(String destDir)

Returns the name of the file that this JCompUnit would be printed to, given a call to print(String, String), or if destDir is null, a call to print().

Parameters:

destDir - The destination directory. This may be null.

Returns:

The name of the file that this JCompUnit would be printed to.
