Constructor Detail

FieldReference

public FieldReference()

Field reference.

FieldReference

public FieldReference(Identifier id)

Field reference.

Parameters:

id - an identifier.

FieldReference

public FieldReference(ReferencePrefix prefix,
                      Identifier id)

Field reference.

Parameters:

prefix - a reference prefix.

id - an identifier.

FieldReference

protected FieldReference(FieldReference proto)

Field reference.

Parameters:

proto - a field reference.

Method Detail

deepClone

public FieldReference deepClone()

Deep clone.

Specified by:

deepClone in interface Expression

Specified by:

deepClone in interface SourceElement

Overrides:

deepClone in class VariableReference

Returns:

the object.

makeParentRoleValid

public void makeParentRoleValid()

Make parent role valid.

Specified by:

makeParentRoleValid in interface NonTerminalProgramElement

Overrides:

makeParentRoleValid in class VariableReference

getChildCount

public int getChildCount()

Returns the number of children of this node.

Specified by:

getChildCount in interface NonTerminalProgramElement

Overrides:

getChildCount in class VariableReference

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

Overrides:

getChildAt in class VariableReference

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

Overrides:

getChildPositionCode in class VariableReference

Parameters:

child - the exact child to look for.

Returns:

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

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

getReferencePrefix

public ReferencePrefix getReferencePrefix()

Get reference prefix.

Specified by:

getReferencePrefix in interface ReferenceSuffix

Returns:

the reference prefix.

setReferencePrefix

public void setReferencePrefix(ReferencePrefix prefix)

Set reference prefix.

Parameters:

prefix - a reference prefix.

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

getExpressionCount

public int getExpressionCount()

Get the number of expressions in this container.

Specified by:

getExpressionCount in interface ExpressionContainer

Returns:

the number of expressions.

getExpressionAt

public Expression getExpressionAt(int index)

Specified by:

getExpressionAt in interface ExpressionContainer

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

Overrides:

replaceChild in class VariableReference

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.

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 VariableReference

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

Overrides:

accept in class VariableReference

Parameters:

v - a source visitor.
