Class TypeName

java.lang.Object
  com.ibm.wala.types.TypeName

All Implemented Interfaces:

java.io.Serializable

public final class TypeName
extends java.lang.Object
implements java.io.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

public static TypeName findOrCreate(java.lang.String name)
                             throws java.lang.IllegalArgumentException

Throws:

java.lang.IllegalArgumentException

findOrCreateClass

public static TypeName findOrCreateClass(Atom packageName,
                                         Atom className)

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toUnicodeString

public java.lang.String toUnicodeString()

string2TypeName

public static TypeName string2TypeName(java.lang.String s)
                                throws java.lang.IllegalArgumentException

Parameters:

s - a String like Ljava/lang/Object

Returns:

the corresponding TypeName

Throws:

java.lang.IllegalArgumentException - if s is null

findOrCreateClassName

public static TypeName findOrCreateClassName(java.lang.String packageName,
                                             java.lang.String className)

parseForArrayElementName

public TypeName parseForArrayElementName()

Returns:

the name of the array element type for an array

getArrayTypeForElementType

public TypeName getArrayTypeForElementType()

Returns:

a type name that represents an array of this element type

getDimensionality

public final int getDimensionality()

Returns:

the dimensionality of the type. By convention, class types have dimensionality 0, primitves -1, and arrays the number of [ in their descriptor.

isArrayType

public final boolean isArrayType()

Does 'this' refer to an array?

isPrimitiveType

public final boolean isPrimitiveType()

Does 'this' refer to a primitive type

getInnermostElementType

public final TypeName getInnermostElementType()

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)
