de.hybris.platform.servicelayer.internal.converter.util.ModelUtils

public final class ModelUtils
extends Object

This class contains some utility methods for getting/setting field values and check for methods/field. These methods are based on reflection.

Method Summary

Modifier and Type	Method and Description
static boolean	enumEquals(HybrisEnumValue enum1, Object obj) Compares enum object with another object.
static boolean	existsField(Class model, String field) Returns true if in the given class model a field by the given fieldname exists.
static boolean	existsMethod(Class model, String method) Returns true if in the given class model a method by the given method name exists.
static Class	getFieldType(Class model, String field) Returns a Class object that identifies the declared type for the given field name of the given model class.
static Object	getFieldValue(Object model, String field) Returns the value of the field (given by the field name) from the given model.
static boolean	isPrimitiveField(Class model, String field) Returns (per reflection) true if in the class the field by it's given field name is a primitive type.
static boolean	setFieldValue(Object model, String field, Object value) Sets in the given model the given value into the field by the given field name per reflection and returns true if this was successful.

Method Detail

getFieldValue

public static Object getFieldValue(Object model,
                                   String field)

Returns the value of the field (given by the field name) from the given model. per reflection. Searches all superclasses of the model.

Parameters:

model - the model

field - the field name

Returns:

null if not such field at the model exists, otherwise the value object is returned

Throws:

IllegalStateException - if an unexpected reflection exception occurs.

setFieldValue

public static boolean setFieldValue(Object model,
                                    String field,
                                    Object value)

Sets in the given model the given value into the field by the given field name per reflection and returns true if this was successful.

Parameters:

model - the model where the value should be set

field - the field name at the model

value - the value to be set

Returns:

false if no such fiel at the model was found

isPrimitiveField

public static boolean isPrimitiveField(Class model,
                                       String field)

Returns (per reflection) true if in the class the field by it's given field name is a primitive type.

Parameters:

model - the class model

field - the field name

Returns:

false if the field is not primitive or the field doesn't exist in the class

getFieldType

public static Class getFieldType(Class model,
                                 String field)

Returns a Class object that identifies the declared type for the given field name of the given model class.

Parameters:

model - the model class

field - the field name

Returns:

null if no such field was found, otherwise the type class is returned

existsMethod

public static boolean existsMethod(Class model,
                                   String method)

Returns true if in the given class model a method by the given method name exists. The method can have any signature.

Parameters:

model - the class model

method - the method name

Returns:

false if no such method exists in the given class model

existsField

public static boolean existsField(Class model,
                                  String field)

Returns true if in the given class model a field by the given fieldname exists. Searches all superclasses of the given class model.

Parameters:

model - the class model

field - the fieldname

Returns:

false if no such field exists in the given class model

enumEquals

public static boolean enumEquals(HybrisEnumValue enum1,
                                 Object obj)

Compares enum object with another object. Used inside generated dynamic enum values.

Parameters:

enum1 - the first enum

obj - the second enum

Returns:

true if both objects are dynamic enum values and have the same type and code; please note that type and code are case insensitive!
