All Implemented Interfaces:

TypeDeclarationContainer, Expression, ExpressionStatement, ExpressionContainer, LoopInitializer, ModelElement, NonTerminalProgramElement, ProgramElement, Reference, ConstructorReference, MemberReference, MethodOrConstructorReference, ReferencePrefix, ReferenceSuffix, TypeReferenceContainer, SourceElement, Statement, SVSubstitute

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.

children - the children of this AST element as KeY classes. a ClassDeclaration (in case of an anonymous class decl) a TypeReference (the referred type) 2 of Expression (the first Expression as left hand side, the second as right hand side), Comments; does NOT contain: a ReferencePrefix for the constructor as it might be mixed up with the TypeReference

rp - a ReferencePrefix as access path for the constructor

New

public New(Expression[] arguments,
           TypeReference type,

rp - a ReferencePrefix as access path for the constructor

Method Detail

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()

getFirstElementIncludingBlocks

public SourceElement getFirstElementIncludingBlocks()

Description copied from interface: SourceElement

Finds the source element that occurs first in the source.

Specified by:

getFirstElementIncludingBlocks in interface SourceElement

Overrides:

getFirstElementIncludingBlocks in class Operator

Returns:

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

See Also:

SourceElement.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()

getArity

public int getArity()

Description copied from class: Operator

getArity() == getASTchildren().size()

Specified by:

getArity in class Operator

getPrecedence

public int getPrecedence()

Description copied from class: Operator

0 is the "highest" precedence (obtained by parantheses), 13 the "lowest".

Specified by:

getPrecedence in class Operator

getNotation

public int getNotation()

Specified by:

getNotation in class Operator

Returns:

INFIX, PREFIX, or POSTFIX.

public int getTypeDeclarationCount()

Description copied from interface: TypeDeclarationContainer

Get the number of type declarations in this container.

Specified by:
