Class ImportsTracker

java.lang.Object

org.jibx.schema.codegen.ImportsTracker

public class ImportsTracker
extends Object

Organizer for imports to a source file. This is a state-based organizer, which allows tentative imports to be overridden up until the point where the map from fully-qualified class names to unqualified names is constructed by calling getNameMap(), then further non-conflicting imports are allowed until the final import list is constructed by calling freeze(String).

Constructor Detail

ImportsTracker

public ImportsTracker(String pkgname)

Constructor.

Parameters:

pkgname - containing package name

Method Detail

addLocalType

public void addLocalType(String name,
                String fqname)

Add local definition name to those visible in class. If the name conflicts with an import, the import is removed to force fully-qualified references.

Parameters:

name - simple class name

fqname - fully qualified class name

addImport

protected boolean addImport(String fqname,
                boolean force)

Add import for class. If the requested import doesn't conflict with the current set it's added.

Parameters:

fqname - fully qualified class name

force - force replacement of current import

Returns:

true if added as import

isQualified

public boolean isQualified(String fqname)

Check if type needs qualified references.

Parameters:

fqname - fully qualified class name

Returns:

true if needs qualification

getNameMap

public Map getNameMap()

Get map from imported fully-qualified class names to short names. Once this method is called, overrides of existing imports are blocked (since the existing imports may have been used), though added non-conflicting imports can still be added.

Returns:

map

getName

public String getName(String type)

Get the name to be used for a type. If the type has been imported this returns the short form of the name; otherwise it just returns the fully-qualified name. This method forces a call to getNameMap(), which in turn blocks removing any imports later.

Parameters:

type - fully-qualified type name

Returns:

name

freeze

public List freeze(String cname)

Freeze imports and return a list of imports.

Parameters:

cname - simple name of class (used to identify inner class references)

Returns:

list
