Constructor Detail

MetaClassReference

public MetaClassReference()

Meta class reference.

MetaClassReference

public MetaClassReference(TypeReference reference)

Meta class reference.

Parameters:

reference - a type reference.

MetaClassReference

protected MetaClassReference(MetaClassReference proto)

Meta class reference.

Parameters:

proto - a meta class reference.

Method Detail

deepClone

public MetaClassReference deepClone()

Deep clone.

Specified by:

deepClone in interface Expression

Specified by:

deepClone in interface SourceElement

Returns:

the object.

makeParentRoleValid

public void makeParentRoleValid()

Make parent role valid.

Specified by:

makeParentRoleValid in interface NonTerminalProgramElement

Overrides:

makeParentRoleValid in class JavaNonTerminalProgramElement

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)

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.

getReferenceSuffix

public ReferenceSuffix getReferenceSuffix()

Get reference suffix.

Specified by:

getReferenceSuffix in interface ReferencePrefix

Returns:

the reference suffix.

setReferenceSuffix

public void setReferenceSuffix(ReferenceSuffix path)

Set reference suffix.

Specified by:

setReferenceSuffix in interface ReferencePrefix

Parameters:

path - a reference suffix.

getReferencePrefix

public ReferencePrefix getReferencePrefix()

Get reference prefix.

Specified by:

getReferencePrefix in interface ReferenceSuffix

Returns:

the reference prefix.

setReferencePrefix

public void setReferencePrefix(ReferencePrefix accessPath)

Set reference prefix.

Parameters:

accessPath - a reference prefix.

getExpressionContainer

public ExpressionContainer getExpressionContainer()

Get expression container.

Specified by:

getExpressionContainer in interface Expression

Returns:

the expression container.

setExpressionContainer

public void setExpressionContainer(ExpressionContainer c)

Set expression container.

Specified by:

setExpressionContainer in interface Expression

Parameters:

c - an expression container.

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()

Get type reference.

Returns:

the type reference.

setTypeReference

public void setTypeReference(TypeReference ref)

Set type reference.

Parameters:

ref - a type reference.

getFirstElement

public SourceElement getFirstElement()

Description copied from class: JavaSourceElement

Finds the source element that occurs first 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:

getFirstElement in interface SourceElement

Overrides:

getFirstElement in class JavaSourceElement

Returns:

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

JavaSourceElement.toSource(), JavaSourceElement.getStartPosition()

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.
