Class TypeMetadata

java.lang.Object

pl.jalokim.utils.reflection.TypeMetadata

public class TypeMetadata
extends Object

Class which represents real types for generic types. This can store information about real generic nested type in classes and in fields. This needs all generic types resolved as real types.

Method Summary

Modifier and Type	Method and Description
TypeMetadata	getByGenericLabel(String genericLabel) It returns metadata for raw generic label for current class, it not search in parents classes.
String	getCanonicalName() It returns canonical class name for current raw type.
TypeMetadata	getGenericType(int index) It returns metadata for generic type under provided index.
TypeMetadata	getMetaForField(String fieldName) It returns metadata for field stored in current raw class It searches for field in whole raw class hierarchy.
TypeMetadata	getTypeMetadataForField(Class<?> fieldOwner, String typeName) It returns resolved metadata for some raw generic type when exists one.
boolean	hasGenericTypes() If raw class is generic types then this will return true.
boolean	hasParent() When raw class have parent class which is not raw Object.
boolean	isArrayType()
boolean	isEnumType()
boolean	isHavingElementsType() When is some bag, it means when is array type or some collection.
boolean	isMapType()
boolean	isSimpleType() When is simple primitive type.
String	toString()

Method Detail

hasGenericTypes

public boolean hasGenericTypes()

If raw class is generic types then this will return true. And if raw class is array then it has generic types too.

Returns:

boolean

getCanonicalName

public String getCanonicalName()

It returns canonical class name for current raw type.

Returns:

canonical class name

getTypeMetadataForField

public TypeMetadata getTypeMetadataForField(Class<?> fieldOwner,
                                            String typeName)

It returns resolved metadata for some raw generic type when exists one.

Parameters:

fieldOwner - real owner of raw generic field.

typeName - real name of label from generic class.

Returns:

instance of TypeMetadata

getByGenericLabel

public TypeMetadata getByGenericLabel(String genericLabel)

It returns metadata for raw generic label for current class, it not search in parents classes.

Parameters:

genericLabel - real name of generic raw type. For example raw type is List<E> It Returns real metadata for E label in List.

Returns:

instance of TypeMetadata

isEnumType

public boolean isEnumType()

isArrayType

public boolean isArrayType()

isMapType

public boolean isMapType()

isHavingElementsType

public boolean isHavingElementsType()

When is some bag, it means when is array type or some collection.

Returns:

true when is array type or some collection.

isSimpleType

public boolean isSimpleType()

When is simple primitive type.

Returns:

true when is simple primitive type.

hasParent

public boolean hasParent()

When raw class have parent class which is not raw Object.

Returns:

boolean value

getMetaForField

public TypeMetadata getMetaForField(String fieldName)

It returns metadata for field stored in current raw class It searches for field in whole raw class hierarchy.

Parameters:

fieldName - real field name

Returns:

metadata for field

getGenericType

public TypeMetadata getGenericType(int index)

It returns metadata for generic type under provided index. For arrays type, type of array it stored under first index. Array is treated as generic list.

Parameters:

index - of generic type for current raw type.

Returns:

metadata of generic type under provided index.

toString

public String toString()

Overrides:

toString in class Object
