public class ArrayData
extends SymbolData

Represents the data for an array class. There are two states of SymbolData. One is a continuation which is created when a type is referenced, but the corresponding class has not been read for its members. The other is a complete SymbolData containing all of the member data. This ArrayData stores the SymbolData of its element type inside of it.

Constructor Summary

ArrayData(SymbolData sd, LanguageLevelVisitor llv, SourceInfo si)
Creates a new ArrayData corresponding to the elementType sd.

Method Summary

boolean	equals(Object obj) Returns true if the provided Object is equal to this symbol data.
int	getDimensions() Return the dimensions of this array (the level of nesting until a non-array element type is found).
SymbolData	getElementType()
ModifiersAndVisibility	getMav()
Data	getOuterData() Delegates to the outer data of your element type
String	getPackage()
int	hashCode() Provides a hashcode method that distinguishes between array datas based on name
boolean	isAssignableTo(SymbolData assignTo, JavaVersion version) Returns true only under the following conditions: if assignTo is a class, assignTo must be java.lang.Object.
boolean	isCastableTo(SymbolData castTo, JavaVersion version) Return true iff castTo is a class type and is Object castTo is an interface type that is Serializable or Clonable castTo is an array type then this and castTo must have element types that are either the same primitive type or (both reference types and this's element type must be castable to castTo's element type)
void	setMav(ModifiersAndVisibility mv) Sets the ModifiersAndVisibility of the element type to the specified value.
void	setOuterData(Data outerData) A Noop, because arrays shouldn't have outer data
void	setPackage(String s) Set the package of the element type to be the specified package:

Constructor Detail

ArrayData

public ArrayData(SymbolData sd,
                 LanguageLevelVisitor llv,
                 SourceInfo si)

Creates a new ArrayData corresponding to the elementType sd.

Parameters:

sd - The SymbolData element type; may be a continuation

llv - The LanguageLevelVisitor who created this ArrayData.

si - The SourceInfo corresponding to this ArrayData.

Method Detail

getPackage

public String getPackage()

Overrides:

getPackage in class SymbolData

Returns:

the package of the element type

setPackage

public void setPackage(String s)

Set the package of the element type to be the specified package:

Overrides:

setPackage in class SymbolData

Parameters:

s - The package to use

getMav

public ModifiersAndVisibility getMav()

Overrides:

getMav in class Data

Returns:

the modifiersAndVisibility for this data.

setMav

public void setMav(ModifiersAndVisibility mv)

Sets the ModifiersAndVisibility of the element type to the specified value.

Overrides:

setMav in class Data

Parameters:

mv - The ModifiersAndVisibility to use.

getElementType

public SymbolData getElementType()

Returns:

the SymbolData element type corresponding to the elements of this array.

getOuterData

public Data getOuterData()

Delegates to the outer data of your element type

Overrides:

getOuterData in class Data

Returns:

the directly enclosing outer data.

setOuterData

public void setOuterData(Data outerData)

A Noop, because arrays shouldn't have outer data

Overrides:

setOuterData in class Data

Parameters:

outerData - The Data that encloses this data.

equals

public boolean equals(Object obj)

Description copied from class: SymbolData

Returns true if the provided Object is equal to this symbol data. SymbolDatas are equal if their fields are the same.

Overrides:

equals in class SymbolData

hashCode

public int hashCode()

Provides a hashcode method that distinguishes between array datas based on name

Overrides:

hashCode in class SymbolData

isAssignableTo

public boolean isAssignableTo(SymbolData assignTo,
                              JavaVersion version)

Returns true only under the following conditions: if assignTo is a class, assignTo must be java.lang.Object. if assignTo is an interferface, then it must be Serializable or Clonable. if assignTo is an array, then if this's element type is a primitive assignTo must have the same primitive element type and if this's element type is a reference type, this's reference type must be assignable to assignTo's element type.

Overrides:

isAssignableTo in class SymbolData

isCastableTo

public boolean isCastableTo(SymbolData castTo,
                            JavaVersion version)

Return true iff castTo is a class type and is Object castTo is an interface type that is Serializable or Clonable castTo is an array type then this and castTo must have element types that are either the same primitive type or (both reference types and this's element type must be castable to castTo's element type)

Overrides:

isCastableTo in class SymbolData

Parameters:

castTo - The TypeData we are trying to cast to. (castTo) this

Returns:

true If the cast is legal, false otherwise.

getDimensions

public int getDimensions()

Return the dimensions of this array (the level of nesting until a non-array element type is found).
