Method Details

asType

TypeMirror asType()

Returns a pseudo-type for this module.

Specified by:

asType in interface Element

Returns:

a pseudo-type for this module

NoType, TypeKind.MODULE

getQualifiedName

Name getQualifiedName()

Returns the fully qualified name of this module. For an unnamed module, an empty name is returned.

Specified by:

getQualifiedName in interface QualifiedNameable

API Note:

If the module name consists of one identifier, then this method returns that identifier, which is deemed to be module's fully qualified name despite not being in qualified form. If the module name consists of more than one identifier, then this method returns the entire name.

Returns:

the fully qualified name of this module, or an empty name if this is an unnamed module

See Java Language Specification:

6.2 Names and Identifiers

getSimpleName

Name getSimpleName()

Returns the simple name of this module. For an unnamed module, an empty name is returned.

Specified by:

getSimpleName in interface Element

API Note:

If the module name consists of one identifier, then this method returns that identifier. If the module name consists of more than one identifier, then this method returns the rightmost such identifier, which is deemed to be the module's simple name.

Returns:

the simple name of this module or an empty name if this is an unnamed module
