public TypeWrapper(Type<T> delegate)

Method Details

getDelegate

public final Type<T> getDelegate()

getJavaType

@Deprecated
public final String getJavaType()

Deprecated.

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

@Deprecated
public Class<T> resolveJavaType()

Deprecated.

Specified by:

resolveJavaType in interface Type<T>

Returns:

the resolved Java Class associated with the type.

getName

public final String getName()

Description copied from interface: Type

Returns logical name of the type

Specified by:

getName in interface Type<T>

Returns:

logical name

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

getJavaClass

public Class<T> getJavaClass()

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:

getJavaClass in interface Type<T>

Returns:

the Java Class associated with the type.

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
