Method Details

getValue

@Nullable
public Object getValue(Object containingObject)

Specified by:

getValue in interface ReflectField

Parameters:

containingObject - object which contains this field

Returns:

value of this field for containingObject; might be null.
This method will throw when invoked on a containingObject that is not instanceof getType().

getName

public String getName()

Specified by:

getName in interface ReflectField

Returns:

field name as it appears in code (or the closest thing to it). Can only contain valid Java identifier characters, e.g. cannot have a "."

getGenericType

public Type getGenericType()

Specified by:

getGenericType in interface ReflectField

Returns:

full generic field type

See Also:

• ReflectField.getType()

getType

public Class<?> getType()

Specified by:

getType in interface ReflectField

Returns:

raw field type

See Also:

• ReflectField.getType()

getValueType

public FieldValueType getValueType()

Description copied from interface: ReflectField

Returns this field's value type for the purposes of data-binding. The type returned is very vague, e.g., all POJOs and Java records will have type of COMPOSITE meaning they will be mapped into multiple columns by default; all fixed-size integral values will have type of INTEGER; and so on.

@Column annotation can influence whether a multi-field type such as a POJO is mapped to one column or multiple columns, see its JavaDoc for more information.

Specified by:

getValueType in interface ReflectField

Returns:

field's value type for the purposes of data-binding

getColumn

public Column getColumn()

Specified by:

getColumn in interface ReflectField

Returns:

@Column annotation, if this field is annotated; null otherwise. Precisely what means "field is annotated" is implementation-dependent: it might mean that the property getter method is annotated, for example.

getReflectType

public ReflectType<?> getReflectType()

Specified by:

getReflectType in interface ReflectField

Returns:

basic reflection information for raw field type

toString

public String toString()

Overrides:

toString in class Object
