Method Summary

protected int	compareTo0(Constant other) Compare the values of this and another instance, which are guaranteed to be of the same class.
boolean	equals(Object other)
static CstType	forBoxedPrimitiveType(Type primitiveType) Returns an instance of this class that represents the wrapper class corresponding to a given primitive type.
Type	getClassType() Gets the underlying type (as opposed to the type corresponding to this instance as a constant, which is always Class).
CstString	getDescriptor() Gets the type descriptor for this instance.
Type	getType() Gets the type associated with this instance.
int	hashCode()
static CstType	intern(Type type) Returns an interned instance of this class for the given type.
boolean	isCategory2() Returns true if this instance is a category-2 constant, meaning it takes up two slots in the constant pool, or false if this instance is category-1.
String	toHuman() Return the "human" string form of this instance.
String	toString()
String	typeName() Returns the human name for the particular type of constant this instance is.

Constructor Detail

CstType

public CstType(Type type)

Constructs an instance.

Parameters:

type - non-null; the underlying type

Method Detail

forBoxedPrimitiveType

public static CstType forBoxedPrimitiveType(Type primitiveType)

Returns an instance of this class that represents the wrapper class corresponding to a given primitive type. For example, if given Type.INT, this method returns the class reference java.lang.Integer.

Parameters:

primitiveType - non-null; the primitive type

Returns:

non-null; the corresponding wrapper class

intern

public static CstType intern(Type type)

Returns an interned instance of this class for the given type.

Parameters:

type - non-null; the underlying type

Returns:

non-null; an appropriately-constructed instance

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo0

protected int compareTo0(Constant other)

Compare the values of this and another instance, which are guaranteed to be of the same class. Subclasses must implement this.

Specified by:

compareTo0 in class Constant

Parameters:

other - non-null; the instance to compare to

Returns:

-1, 0, or 1, as usual for a comparison

toString

public String toString()

Overrides:

toString in class Object

getType

public Type getType()

Gets the type associated with this instance.

Returns:

non-null; the type

typeName

public String typeName()

Returns the human name for the particular type of constant this instance is.

Specified by:

typeName in class Constant

Returns:

non-null; the name

isCategory2

public boolean isCategory2()

Returns true if this instance is a category-2 constant, meaning it takes up two slots in the constant pool, or false if this instance is category-1.

Specified by:

isCategory2 in class Constant

Returns:

true iff this instance is category-2

toHuman

public String toHuman()

Return the "human" string form of this instance. This is generally less "debuggy" than toString().

Returns:

non-null; the human string form

getClassType

public Type getClassType()

Gets the underlying type (as opposed to the type corresponding to this instance as a constant, which is always Class).

Returns:

non-null; the type corresponding to the name

getDescriptor

public CstString getDescriptor()

Gets the type descriptor for this instance.

Returns:

non-null; the descriptor
