Class TypeDescription

java.lang.Object

org.yaml.snakeyaml.TypeDescription

public class TypeDescription
extends Object

Provides additional runtime information necessary to create a custom Java instance. In general this class is thread-safe and can be used as a singleton, the only exception being the PropertyUtils field. A singleton PropertyUtils should be constructed and shared between all YAML Constructors used if a singleton TypeDescription is used, since Constructor sets its propertyUtils to the TypeDescription that is passed to it, hence you may end up in a situation when propertyUtils in TypeDescription is from different Constructor.

Get represented type (class)

Returns:

type (class) to be described.

@Deprecated
public void putListPropertyType(String property,
                                  Class<? extends Object> type)

Deprecated.

Specify that the property is a type-safe List.

Parameters:

property - name of the JavaBean property

type - class of List values

getListPropertyType

@Deprecated
public Class<? extends Object> getListPropertyType(String property)

Deprecated.

Get class of List values for provided JavaBean property.

Parameters:

property - property name

Returns:

class of List values

putMapPropertyType

@Deprecated
public void putMapPropertyType(String property,
                                 Class<? extends Object> key,
                                 Class<? extends Object> value)

Deprecated.

Specify that the property is a type-safe Map.

Parameters:

property - property name of this JavaBean

key - class of keys in Map

value - class of values in Map

getMapKeyType

@Deprecated
public Class<? extends Object> getMapKeyType(String property)

Deprecated.

Get keys type info for this JavaBean

Parameters:

property - property name of this JavaBean

Returns:

class of keys in the Map

getMapValueType

@Deprecated
public Class<? extends Object> getMapValueType(String property)

Deprecated.

Get values type info for this JavaBean

Parameters:

property - property name of this JavaBean

Returns:

class of values in the Map

addPropertyParameters

public void addPropertyParameters(String pName,
                         Class<?>... classes)

Adds new substitute for property pName parameterized by classes to this TypeDescription. If pName has been added before - updates parameters with classes.

Parameters:

pName - - parameter name

classes - - parameterized by

toString

public String toString()

Overrides:

toString in class Object

getProperty

public Property getProperty(String name)

substituteProperty

public void substituteProperty(String pName,
                      Class<?> pType,
                      String getter,

                      Class<?>... argParams)

Adds property substitute for pName

Parameters:

                    throws Exception

Throws:

Exception

newInstance

public Object newInstance(Node node)

This method should be overridden for TypeDescription implementations that are supposed to implement instantiation logic that is different from default one as implemented in YAML constructors. Note that even if you override this method, default filling of fields with variables from parsed YAML will still occur later.

Parameters:

node - - node to construct the instance from

Returns:

new instance

newInstance

public Object newInstance(String propertyName,
                 Node node)

finalizeConstruction

public Object finalizeConstruction(Object obj)

Is invoked after entity is filled with values from deserialized YAML

postprocessed deserialized entity
