Constructor Detail

Import

public Import()

Import.

Import

public Import(TypeReference t,
              boolean multi)

Creates a non-static (default) Import. Same as new Import(t, multi, false)

Parameters:

t - a type reference.

multi - indicates the wildcard.

Import

public Import(TypeReference t,
              Identifier id)

Creates a static Import.

Parameters:

t -

multi -

isStatic -

Import

public Import(TypeReference t,
              boolean multi,
              boolean isStatic)

Import

public Import(PackageReference t)

Import.

Parameters:

t - a package reference.

Import

protected Import(Import proto)

Import.

Parameters:

proto - an import.

Method Detail

makeParentRoleValid

public void makeParentRoleValid()

Make parent role valid.

Specified by:

makeParentRoleValid in interface NonTerminalProgramElement

Overrides:

makeParentRoleValid in class JavaNonTerminalProgramElement

deepClone

public Import deepClone()

Deep clone.

Specified by:

deepClone in interface SourceElement

Returns:

the object.

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.

isStaticImport

public boolean isStaticImport()

Checks if this import is a static import (Java 5).

Returns:

wether or not the import is a static import

setMultiImport

public void setMultiImport(boolean multi)

Sets this import to be a multi type import.

Parameters:

multi - denotes the wildcard for this import.

Throws:

java.lang.IllegalArgumentException - if the reference is a package and multi is false .

setStaticImport

public void setStaticImport(boolean isStatic)

setStaticIdentifier

public void setStaticIdentifier(Identifier id)

getStaticIdentifier

public Identifier getStaticIdentifier()

getASTParent

public NonTerminalProgramElement getASTParent()

Get AST parent.

Specified by:

getASTParent in interface ProgramElement

Returns:

the non terminal program element.

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

getChildPositionCode

public int getChildPositionCode(ProgramElement child)

Description copied from interface: NonTerminalProgramElement

Returns the positional code of the given child, or -1 if there is no such child. The result contains an encoding of the relative position of the child as well as the role it has been playing in this parent element. This information is required internally for proper undo of transformations and is to be delivered to the detached method of the ChangeHistory.

Specified by:

getChildPositionCode in interface NonTerminalProgramElement

Parameters:

child - the exact child to look for.

Returns:

the positional code of the given child, or -1.

See Also:

ChangeHistory.detached(recoder.java.ProgramElement, recoder.java.NonTerminalProgramElement, int)

getParent

public CompilationUnit getParent()

Get parent.

Returns:

the compilation unit.

setParent

public void setParent(CompilationUnit u)

Set parent.

Parameters:

u - a compilation unit.

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. Note that if reference is a URQ, this method will return null, although this URQ may denote a Package.

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.

setReference

public void setReference(TypeReferenceInfix t)

Set reference.

Parameters:

t - a type reference infix.

replaceChild

public boolean replaceChild(ProgramElement p,
                            ProgramElement q)

Replace a single child in the current node. The child to replace is matched by identity and hence must be known exactly. The replacement element can be null - in that case, the child is effectively removed. The parent role of the new child is validated, while the parent link of the replaced child is left untouched.

Specified by:

replaceChild in interface NonTerminalProgramElement

Parameters:

p - the old child.

p - the new child.

Returns:

true if a replacement has occured, false otherwise.

Throws:

java.lang.ClassCastException - if the new child cannot take over the role of the old one.

accept

public void accept(SourceVisitor v)

Description copied from interface: SourceElement

Receive a visitor, for instance a pretty printer.

Specified by:

accept in interface SourceElement

Parameters:

v - a source visitor.
