public class New
extends TypeOperator
implements ConstructorReference, ExpressionStatement, ReferencePrefix, ReferenceSuffix, TypeDeclarationContainer

The object allocation operator. There are two variants for New:

1. Class constructor call
   new XYZ(a₁, ..., a_n)
   if getType() instanceof UserType
2. Anonymous Inner Class definition and construction
   new XYZ(a₁, ..., a_n) { m₁, ..., m_k }
   if getType() instanceof UserType && getClassDeclaration() !=null

The access path is null in most cases, except when an inner class constructor is invoked from an outer instance.

Deep clone.

Specified by:

deepClone in interface Expression

Specified by:

deepClone in interface ExpressionStatement

Specified by:

deepClone in interface SourceElement

Specified by:

Returns:

the object.

makeParentRoleValid

public void makeParentRoleValid()

Specified by:

makeParentRoleValid in interface NonTerminalProgramElement

Overrides:

makeParentRoleValid in class TypeOperator

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 Operator

Returns:

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

See Also:

JavaSourceElement.toSource(), JavaSourceElement.getStartPosition()

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 Operator

Returns:

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

See Also:

JavaSourceElement.toSource(), JavaSourceElement.getEndPosition()

getASTParent

public NonTerminalProgramElement getASTParent()

Get AST parent.

Specified by:

getASTParent in interface ProgramElement

Overrides:

getASTParent in class Operator

Returns:

the non terminal program element.

getArity

public int getArity()

Get arity.

Specified by:

getArity in class Operator

Returns:

the int value.

getPrecedence

public int getPrecedence()

Get precedence.

Specified by:

getPrecedence in class Operator

Returns:

the int value.

getNotation

public int getNotation()

Get notation.

Specified by:

getNotation in class Operator

Returns:

the int value.

getStatementContainer

public StatementContainer getStatementContainer()

Get statement container.

Specified by:

getStatementContainer in interface Statement

Returns:

the statement container.

getExpressionContainer

public ExpressionContainer getExpressionContainer()

Get expression container.

Specified by:

getExpressionContainer in interface Expression

Overrides:

getExpressionContainer in class Operator

Returns:

the expression container.

setExpressionContainer

public void setExpressionContainer(ExpressionContainer parent)

Set expression container.

Specified by:

setExpressionContainer in interface Expression

Overrides:

setExpressionContainer in class Operator

Parameters:

parent - an expression container.

setStatementContainer

public void setStatementContainer(StatementContainer parent)

Set statement container.

Specified by:

setStatementContainer in interface Statement

Parameters:

parent - a statement container.

getClassDeclaration

public ClassDeclaration getClassDeclaration()

Get class declaration.

Returns:

the class declaration.

setClassDeclaration

public void setClassDeclaration(ClassDeclaration decl)

Set class declaration.

Parameters:

decl - a class declaration.

getChildCount

public int getChildCount()

Returns the number of children of this node.

Overrides:

getChildAt in class Operator

Parameters:

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

Returns:

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:

child - the exact child to look for.

Returns:

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

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 TypeOperator

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.

Get reference prefix.

Specified by:

getReferencePrefix in interface ReferenceSuffix

Returns:

the reference prefix.

setReferencePrefix

public void setReferencePrefix(ReferencePrefix x)

Set reference prefix.

list - an expression mutable list.

accept

public void accept(SourceVisitor v)
