public Import(ExtList children,
              boolean isMultiImport)

children may contain: TypeReference (for import), a Comment

Parameters:

isMultiImport - indicates whether the import contains multiple imports

Import

public Import()

Import.

Import

public Import(TypeReference t,
              boolean multi)

Import.

Parameters:

t - a type reference.

Method Detail

getLastElement

public SourceElement getLastElement()

Description copied from class: JavaSourceElement

Finds the source element that occurs last in the source. The default implementation returns this element, which is correct for all terminal program elements, and many non terminals such as statements and prefixed operators.

Specified by:

getLastElement in interface SourceElement

Overrides:

getLastElement in class JavaSourceElement

Returns:

the last source element in the syntactical representation of this element, may be equals to this element.

See Also:

JavaSourceElement.toSource(), JavaSourceElement.getEndPosition()

isMultiImport

public boolean isMultiImport()

Checks if this import is a multi type import, also known as type-on-demand import.

Returns:

the kind of this import.

getChildCount

public int getChildCount()

Returns the number of children of this node.

Specified by:

getChildCount in interface NonTerminalProgramElement

Returns:

an int giving the number of children of this node

getChildAt

public ProgramElement getChildAt(int index)

Returns the child at the specified index in this node's "virtual" child array

Specified by:

getChildAt in interface NonTerminalProgramElement

Parameters:

index - an index into this node's "virtual" child array

Returns:

the program element at the given position

Throws:

java.lang.ArrayIndexOutOfBoundsException - if index is out of bounds

getTypeReferenceCount

public int getTypeReferenceCount()

Get the number of type references in this container.

Specified by:

getTypeReferenceCount in interface TypeReferenceContainer

Returns:

the number of type references.

getTypeReferenceAt

public TypeReference getTypeReferenceAt(int index)

Specified by:

getTypeReferenceAt in interface TypeReferenceContainer

getTypeReference

public TypeReference getTypeReference()

Returns the type reference of this import, if there is one.

Returns:

the reference of this import statement.

getPackageReference

public PackageReference getPackageReference()

Returns the package reference of this import, if there is one.

Specified by:

getPackageReference in interface PackageReferenceContainer

Returns:

the reference of this import statement.

getReference

public TypeReferenceInfix getReference()

Returns the reference of this import, either a type or a package reference.

Returns:

the reference of this import statement.

visit

public void visit(Visitor v)

calls the corresponding method of a visitor in order to perform some action/transformation on this element

Specified by:

visit in interface SourceElement

Parameters:

v - the Visitor

prettyPrint

public void prettyPrint(PrettyPrinter p)
                 throws java.io.IOException

Description copied from class: JavaSourceElement

Pretty printing the source element.

Specified by:

prettyPrint in interface SourceElement

Overrides:

prettyPrint in class JavaProgramElement

Parameters:

p - a pretty printer.

Throws:

java.io.IOException - occasionally thrown.
