TypeWrapper

public TypeWrapper(Type<T> delegate)

Method Detail

getDelegate

public final Type<T> getDelegate()

getId

public final int getId()

Description copied from interface: Type

Each type is assigned a unique auto-increment int identifier which developers can use in SPI implementations, for example in sharding/partitioning data collections.

Specified by:

getId in interface Type<T>

Returns:

unique type identifier.

getJavaType

public final String getJavaType()

Description copied from interface: Type

There can be only one Type with the given name, but there could be many types associated with a specific Java Class. This method returns the associated Java type.

Specified by:

getJavaType in interface Type<T>

Returns:

name of the Java Class associated with the type.

resolveJavaType

public Class<T> resolveJavaType()

Specified by:

resolveJavaType in interface Type<T>

getName

public final String getName()

Specified by:

getName in interface Named

getDeclaredFields

public Collection<TypeField> getDeclaredFields()

Description copied from interface: Type

Method returns ALL known fields, both explicitly declared and resolved.

Specified by:

getDeclaredFields in interface Type<T>

Returns:

Collection of declared fields

TypeField

getField

public TypeField getField(String name)

Description copied from interface: Type

Returns a declared field with the given name. If no such field was explicitly declared, an attempt will be made to resolve the respective field/getter of the declared Java class. If no such field or getter is found, the method will throw IllegalArgumentException

Empty field name has a special meaning of the "this" value, i.e. such field's values represent the type's instances themself.

Specified by:

getField in interface Type<T>

Parameters:

name - field name or empty string if the field denotes the type's this value

Returns:

declared or resolved field

declareField

public <V> TypeField declareField(String name,
                                  Class<V> type,
                                  Function<T,V> function)

Description copied from interface: Type

Field declaration with a Function as value reader.

Specified by:

declareField in interface Type<T>

Type Parameters:

V - field value generic type

Parameters:

name - field name

type - field value class

function - the function that will be used to read field's value

Returns:

a newly created field or an existing one if already declared/resolved

copyOf

public Type<T> copyOf()

Specified by:

copyOf in interface Copyable<T>

equals

public final boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public final int hashCode()

Overrides:

hashCode in class Object
