Method Detail

resolver

public Resolver resolver()

Description copied from interface: Package

A resolver to access member packages and classes of the package.

Specified by:

resolver in interface Package

copy

public java.lang.Object copy()

Specified by:

copy in interface Copy

Overrides:

copy in class TypeObject_c

declaration

public Declaration declaration()

Description copied from interface: Declaration

Get the original declaration.

Specified by:

declaration in interface Declaration

setDeclaration

public void setDeclaration(Declaration decl)

Description copied from interface: Declaration

Set the original declaration.

Specified by:

setDeclaration in interface Declaration

equalsImpl

public boolean equalsImpl(TypeObject o)

Description copied from class: TypeObject_c

Default implementation is pointer equality.

Specified by:

equalsImpl in interface TypeObject

Overrides:

equalsImpl in class TypeObject_c

See Also:

TypeObject_c.equalsImpl(TypeObject), Object.hashCode()

packageEquals

public final boolean packageEquals(Package p)

Description copied from interface: Package

Return true if this package is equivalent to p.

Specified by:

packageEquals in interface Package

packageEqualsImpl

public boolean packageEqualsImpl(Package p)

Description copied from interface: Package

Return true if this package is equivalent to p.

Specified by:

packageEqualsImpl in interface Package

isType

public boolean isType()

Description copied from interface: Qualifier

Return true if the qualifier is a type.

Specified by:

isType in interface Qualifier

isPackage

public boolean isPackage()

Description copied from interface: Qualifier

Return true if the qualifier is a package.

Specified by:

isPackage in interface Qualifier

toType

public Type toType()

Description copied from interface: Qualifier

Cast the qualifier to a type, or return null. This method will probably be deprecated.

Specified by:

toType in interface Qualifier

toPackage

public Package toPackage()

Description copied from interface: Qualifier

Cast the qualifier to a package, or return null. This method will probably be deprecated.

Specified by:

toPackage in interface Qualifier

prefix

public Package prefix()

Description copied from interface: Package

The package's outer package.

Specified by:

prefix in interface Package

name

public java.lang.String name()

Description copied from interface: Named

Simple name of the type object. Anonymous classes do not have names.

Specified by:

name in interface Named

translate

public java.lang.String translate(Resolver c)

Description copied from interface: Package

Return a string that is the translation of this package.

Specified by:

translate in interface Package

Parameters:

c - A resolver in which to look up the package.

fullName

public java.lang.String fullName()

Description copied from interface: Named

Full dotted-name of the type object. For a package, top level class, top level interface, or primitive type, this is the fully qualified name. For a member class or interface that is directly enclosed in a class or interface with a fully qualified name, then this is the fully qualified name of the member class or interface. For local and anonymous classes, this method returns a string that is not the fully qualified name (as these classes do not have fully qualified names), but that may be suitable for debugging or error messages.

Specified by:

fullName in interface Named

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

print

public void print(CodeWriter w)

Description copied from interface: Package

Pretty-print this package name to w.

Specified by:

print in interface Package

hashCode

public int hashCode()

Overrides:

hashCode in class TypeObject_c

isCanonical

public boolean isCanonical()

Description copied from interface: TypeObject

Return true if the type object contains no unknown/ambiguous types.

Specified by:

isCanonical in interface TypeObject
