Method Summary

Modifier and Type	Method	Description
Object	asKey(Class<?> rawBase)	Factory method that will create an object that can be used as a key for caching purposes by TypeFactory
static TypeBindings	create(Class<?> erasedType, List<JavaType> typeList)	Factory method for constructing bindings for given class using specified type parameters.
static TypeBindings	create(Class<?> erasedType, JavaType typeArg1)
static TypeBindings	create(Class<?> erasedType, JavaType[] types)
static TypeBindings	create(Class<?> erasedType, JavaType typeArg1, JavaType typeArg2)
static TypeBindings	create(List<String> names, List<JavaType> types)	Factory method for constructing bindings given names and associated types.
static TypeBindings	createIfNeeded(Class<?> erasedType, JavaType typeArg1)	Alternate factory method that may be called if it is possible that type does or does not require type parameters; this is mostly useful for collection- and map-like types.
static TypeBindings	createIfNeeded(Class<?> erasedType, JavaType[] types)	Alternate factory method that may be called if it is possible that type does or does not require type parameters; this is mostly useful for collection- and map-like types.
static TypeBindings	emptyBindings()
boolean	equals(Object o)
JavaType	findBoundType(String name)	Find type bound to specified name, if there is one; returns bound type if so, null if not.
String	getBoundName(int index)
JavaType	getBoundType(int index)	Get the type bound to the variable at index.
JavaType	getBoundTypeOrNull(int index)	Get the type bound to the variable at index.
List<JavaType>	getTypeParameters()	Accessor for getting bound types in declaration order
int	hashCode()
boolean	hasUnbound(String name)
boolean	isEmpty()
protected Object	readResolve()
int	size()	Returns number of bindings contained
String	toString()
protected JavaType[]	typeParameterArray()
TypeBindings	withoutVariable(String name)	Create a new instance with the same bindings as this object, except with the given variable removed.
TypeBindings	withUnboundVariable(String name)	Method for creating an instance that has same bindings as this object, plus an indicator for additional type variable that may be unbound within this context; this is needed to resolve recursive self-references.

Method Details

emptyBindings

public static TypeBindings emptyBindings()

readResolve

protected Object readResolve()

create

public static TypeBindings create(Class<?> erasedType,
 List<JavaType> typeList)

Factory method for constructing bindings for given class using specified type parameters.

create

public static TypeBindings create(Class<?> erasedType,
 JavaType[] types)

create

public static TypeBindings create(Class<?> erasedType,
 JavaType typeArg1)

create

public static TypeBindings create(Class<?> erasedType,
 JavaType typeArg1,
 JavaType typeArg2)

create

public static TypeBindings create(List<String> names,
 List<JavaType> types)

Factory method for constructing bindings given names and associated types.

createIfNeeded

public static TypeBindings createIfNeeded(Class<?> erasedType,
 JavaType typeArg1)

Alternate factory method that may be called if it is possible that type does or does not require type parameters; this is mostly useful for collection- and map-like types.

createIfNeeded

public static TypeBindings createIfNeeded(Class<?> erasedType,
 JavaType[] types)

Alternate factory method that may be called if it is possible that type does or does not require type parameters; this is mostly useful for collection- and map-like types.

withUnboundVariable

public TypeBindings withUnboundVariable(String name)

Method for creating an instance that has same bindings as this object, plus an indicator for additional type variable that may be unbound within this context; this is needed to resolve recursive self-references.

withoutVariable

public TypeBindings withoutVariable(String name)

Create a new instance with the same bindings as this object, except with the given variable removed. This is used to create generic types that are "partially raw", i.e. only have some variables bound.

findBoundType

public JavaType findBoundType(String name)

Find type bound to specified name, if there is one; returns bound type if so, null if not.

isEmpty

public boolean isEmpty()

size

public int size()

Returns number of bindings contained

getBoundName

public String getBoundName(int index)

getBoundType

public JavaType getBoundType(int index)

Get the type bound to the variable at index. If the type is not bound but the index is within size() constraints, this method returns TypeFactory.unknownType() for compatibility. If the index is out of size() constraints, this method will still return null.

getBoundTypeOrNull

public JavaType getBoundTypeOrNull(int index)

Get the type bound to the variable at index. If the type is not bound or the index is within size() constraints, this method returns null.

Since:

2.16

getTypeParameters

public List<JavaType> getTypeParameters()

Accessor for getting bound types in declaration order

hasUnbound

public boolean hasUnbound(String name)

Since:

2.3

asKey

public Object asKey(Class<?> rawBase)

Factory method that will create an object that can be used as a key for caching purposes by TypeFactory

Returns:

An object which can be used as a key in TypeFactory, or null if no key can be created.

Since:

2.8

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

typeParameterArray

protected JavaType[] typeParameterArray()
