Class ClassicBeanStyle

java.lang.Object

org.coliper.ibean.BeanStyle

org.coliper.ibean.beanstyle.ClassicBeanStyle

Direct Known Subclasses:

ClassicBeanStyleWithOptionalSupport

public class ClassicBeanStyle
extends BeanStyle

A BeanStyle implementation that reflects beans of traditional Java bean style as defined in the Java Bean Specification.

For each property for a bean you basically have

• a no-argument getter method starting with "get" and returning the property type
• a setter method starting with "set", returning void and having one parameter with type of the property

After the "set" respectively "get" prefix both methods would have the capitalized property name in their name.
For example a property with name "zipCode" and type String would have following setter and getter: void setZipCode(String c); String getZipCode();

This bean style also exists with Optional support in ClassicBeanStyleWithOptionalSupport.

Method Detail

isGetterMethod

public boolean isGetterMethod(Method method)

Checks if the given method

• does not return void
• has no arguments
• and has a name that has at least four characters and starts with "get" or "is" for boolean properties

Specified by:

isGetterMethod in class BeanStyle

Parameters:

method - the Method to test

Returns:

true if the method matches the requirements for a getter

See Also:

BeanStyle.isGetterMethod(java.lang.reflect.Method)

isSetterMethod

public boolean isSetterMethod(Method method)

Checks if the given method

• returns void
• has exactly one arguments
• and has a name that has at least four characters and starts with "set"

Specified by:

isSetterMethod in class BeanStyle

Parameters:

method - the Method to test

Returns:

true if the method matches the requirements for a setter

BeanStyle.isSetterMethod(java.lang.reflect.Method)

hasGetterMethodSignature

protected boolean hasGetterMethodSignature(Method method)

hasSetterMethodSignature

protected boolean hasSetterMethodSignature(Method method)

convertGetterNameToFieldName

public String convertGetterNameToFieldName(String getterName)

Cuts off "get" and decapitalizes the first character of the remaining.

Specified by:

convertGetterNameToFieldName in class BeanStyle

Parameters:

getterName - the name of a method that has been identified as a potential getter

Returns:

the name of the bean field; names are case sensitive

See Also:

BeanStyle.convertGetterNameToFieldName(java.lang.String)

convertSetterNameToFieldName

public String convertSetterNameToFieldName(String setterName)

Cuts off "set" and decapitalizes the first character of the remaining.

Specified by:

convertSetterNameToFieldName in class BeanStyle

Parameters:

setterName - the name of a method that has been identified as a potential setter

Returns:

the name of the bean field; names are case sensitive

public Class<?> determineFieldTypeFromGetterAndSetter(Class<?> beanType,
                                                      Method getterMethod,
                                                      Method setterMethod)
                                               throws InvalidIBeanTypeException

Description copied from class: BeanStyle

Determines the type of a bean field from given corresponding getter and setter method. Implementations of this method can assume that both given methods have been checked for getter and setter compliance and that both methods match in terms of method names. Implementations need to determine the type of the field and need to check if both getter and setter match to the type. That means that for example not only the given setter should be looked at to find out the field type.

Specified by:

determineFieldTypeFromGetterAndSetter in class BeanStyle

Parameters:

beanType - the examined bean class

getterMethod - a method of the beanType that is proven to be a potential getter

setterMethod - a method of the beanType that is proven to be a potential setter

Returns:

the type of the bean field

Throws:

InvalidIBeanTypeException - if either the type cannot be determined for any reason or if the concluded types of setter and getter do not match
