Enum StandardConverters.ConstructorParameterConverter

java.lang.Object

java.lang.Enum<StandardConverters.ConstructorParameterConverter>

reactor.convert.StandardConverters.ConstructorParameterConverter

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<StandardConverters.ConstructorParameterConverter>, Converter

Enclosing class:

StandardConverters

public static enum StandardConverters.ConstructorParameterConverter
extends java.lang.Enum<StandardConverters.ConstructorParameterConverter>
implements Converter

A Converter that will convert to the target type by creating a new instance of the target type using the source, or a conversion of the source, as the argument that's passed to the target type's constructor.

For conversion to be possible the target type must have a constructor that requires a single argument. In the event of the target type having multiple single-argument constructors, the first single-argument constructor that's found will be used.

Enum Constant Detail

INSTANCE

public static final StandardConverters.ConstructorParameterConverter INSTANCE

The instance of this converter

Method Detail

values

public static StandardConverters.ConstructorParameterConverter[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (StandardConverters.ConstructorParameterConverter c : StandardConverters.ConstructorParameterConverter.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static StandardConverters.ConstructorParameterConverter valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

canConvert

public boolean canConvert(java.lang.Class<?> sourceType,
                          java.lang.Class<?> targetType)

Description copied from interface: Converter

Returns true if objects of sourceType can be converted to targetType. If this method returns true, it means Converter.convert(Object, Class) is capable of converting an instance of sourceType to targetType.

Specified by:

canConvert in interface Converter

Parameters:

sourceType - the source type to convert when (may be null if source is null)

targetType - the target type to convert to (required)

Returns:

true if a conversion can be performed, false if not

convert

public <T> T convert(java.lang.Object source,
                     java.lang.Class<T> targetType)

Description copied from interface: Converter

Convert the source to targetType.

Specified by:

convert in interface Converter

Parameters:

source - the source object to convert (may be null)

targetType - the target type to convert to (required)

Returns:

the converted object, an instance of targetType
