public ParameterProperty(MethodDeclaration method,
                         int parameterNumber)

Method Detail

getName

public java.lang.String getName()

Description copied from interface: Property

Gets the name of this property

Specified by:

getName in interface Property

Returns:

The property name

getPropertyType

public java.lang.Class<?> getPropertyType()

Description copied from interface: Property

What type does this property

Specified by:

getPropertyType in interface Property

Returns:

The type of object that will be returned by Property.getValue(Object)

getValue

public java.lang.Object getValue(java.lang.Object bean)
                          throws ConversionException

Description copied from interface: Property

Get the value of this property of the passed in java bean

Specified by:

getValue in interface Property

Parameters:

bean - The bean to introspect

Returns:

The value assigned to this property of the passed in bean

Throws:

ConversionException - If the reflection access fails

setValue

public void setValue(java.lang.Object bean,
                     java.lang.Object value)
              throws ConversionException

Description copied from interface: Property

Set the value of this property of the passed in java bean

Specified by:

setValue in interface Property

Parameters:

bean - The bean to introspect

value - The value assigned to this property of the passed in bean

Throws:

ConversionException - If the reflection access fails

createChild

public Property createChild(int aNewParameterNumber)

Description copied from interface: Property

Properties may have children where we have nested generic type info. For example with setFoo(List<Map<String, Class<?>> x) we can find type information about the nested bits of generic data.

If calling this method then you almost certainly want to check for an overridden property as defined by the ConverterManager by calling ConverterManager.checkOverride(Property)

Specified by:

createChild in interface Property

Parameters:

aNewParameterNumber - Generally the parameter offset.

Returns:

A Property to describe the nested bit of data

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
