DefaultAccessorNamingStrategy

public DefaultAccessorNamingStrategy()

Method Detail

init

public void init(MapStructProcessingEnvironment processingEnvironment)

Description copied from interface: AccessorNamingStrategy

Initializes the accessor naming strategy with the MapStruct processing environment.

Specified by:

init in interface AccessorNamingStrategy

Parameters:

processingEnvironment - environment for facilities

getMethodType

public MethodType getMethodType(ExecutableElement method)

Description copied from interface: AccessorNamingStrategy

Returns the type of the given method.

Specified by:

getMethodType in interface AccessorNamingStrategy

Parameters:

method - to be analyzed.

Returns:

the method type.

isGetterMethod

public boolean isGetterMethod(ExecutableElement method)

Returns true when the ExecutableElement is a getter method. A method is a getter when it has no parameters, starts with 'get' and the return type is any type other than void, OR the getter starts with 'is' and the type returned is a primitive or the wrapper for boolean. NOTE: the latter does strictly not comply to the bean convention. The remainder of the name is supposed to reflect the property name.

The calling MapStruct code guarantees that the given method has no arguments.

Parameters:

method - to be analyzed

Returns:

true when the method is a getter.

isSetterMethod

public boolean isSetterMethod(ExecutableElement method)

Returns true when the ExecutableElement is a setter method. A setter starts with 'set'. The remainder of the name is supposed to reflect the property name.

The calling MapStruct code guarantees that there's only one argument.

Parameters:

method - to be analyzed

Returns:

true when the method is a setter.

isFluentSetter

protected boolean isFluentSetter(ExecutableElement method)

isAdderMethod

public boolean isAdderMethod(ExecutableElement method)

Returns true when the ExecutableElement is an adder method. An adder method starts with 'add'. The remainder of the name is supposed to reflect the singular property name (as opposed to plural) of its corresponding property. For example: property "children", but "addChild". See also getElementName(ExecutableElement).

The calling MapStruct code guarantees there's only one argument.

Parameters:

method - to be analyzed

Returns:

true when the method is an adder method.

isPresenceCheckMethod

public boolean isPresenceCheckMethod(ExecutableElement method)

Returns true when the ExecutableElement is a presence check method that checks if the corresponding property is present (e.g. not null, not nil, ..). A presence check method method starts with 'has'. The remainder of the name is supposed to reflect the property name.

The calling MapStruct code guarantees there's no argument and that the return type is boolean or a Boolean

Parameters:

method - to be analyzed

Returns:

true when the method is a presence check method.

getPropertyName

public String getPropertyName(ExecutableElement getterOrSetterMethod)

Analyzes the method (getter or setter) and derives the property name. See isGetterMethod(ExecutableElement) isSetterMethod(ExecutableElement). The first three ('get' / 'set' scenario) characters are removed from the simple name, or the first 2 characters ('is' scenario). From the remainder the first character is made into small case (to counter camel casing) and the result forms the property name.

Specified by:

getPropertyName in interface AccessorNamingStrategy

Parameters:

getterOrSetterMethod - getter or setter method.

Returns:

the property name.

getElementName

public String getElementName(ExecutableElement adderMethod)

Adder methods are used to add elements to collections on a target bean. A typical use case is JPA. The convention is that the element name will be equal to the remainder of the add method. Example: 'addElement' element name will be 'element'.

Specified by:

getElementName in interface AccessorNamingStrategy

Parameters:

adderMethod - getter or setter method.

Returns:

the property name.

getQualifiedName

protected static String getQualifiedName(TypeMirror type)

Helper method, to obtain the fully qualified name of a type.

Parameters:

type - input type

Returns:

fully qualified name of type when the type is a DeclaredType, null when otherwise.

getCollectionGetterName

public String getCollectionGetterName(String property)

Description copied from interface: AccessorNamingStrategy

Returns the getter name of the given collection property.

The default implementation will e.g. return "getItems" for "items".

Specified by:

getCollectionGetterName in interface AccessorNamingStrategy

Parameters:

property - to be getterOrSetterMethod.

Returns:

getter name for collection properties
