Package com.ibm.wala.types

Class TypeName

java.lang.Object

com.ibm.wala.types.TypeName

All Implemented Interfaces:

Serializable

public final class TypeName
extends Object
implements Serializable

We've introduced this class to canonicalize Atoms that represent package names.

NB: All package names should use '/' and not '.' as a separator. eg. Ljava/lang/Class

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

string2TypeName

public static TypeName string2TypeName(String s)
                                throws IllegalArgumentException

Parameters:

s - a String like Ljava/lang/Object

Returns:

the corresponding TypeName

Throws:

IllegalArgumentException - if s is null

findOrCreateClassName

public static TypeName findOrCreateClassName(String packageName,
 String className)

parseForArrayElementName

public TypeName parseForArrayElementName()

Returns:

the name of the array element type for an array

getArrayTypeForElementType

Return the innermost element type reference for an array

getPackage

public Atom getPackage()

Returns:

the Atom naming the package for this type.

getClassName

public Atom getClassName()

Returns:

the Atom naming the class for this type (without package)
