Field Detail

getMethod

protected final java.lang.reflect.Method getMethod

This variable stores the method to invoke for getting the value of the property on a given bean. In the case of multiple cardinality, this method is expected to return a Set otherwise an instance of range

domain

protected java.lang.Class<D extends BioPAXElement> domain

This is the Class representing the domain of the property.

range

protected java.lang.Class<R> range

This is the Class representing the range of the property. It is by default an object.

multipleCardinality

protected final boolean multipleCardinality

This is false if there is a cardinality restriction of one on the property.

Constructor Detail

SimplePropertyAccessor

public SimplePropertyAccessor(java.lang.Class<D> domain,
                              java.lang.Class<R> range,
                              boolean multipleCardinality,
                              java.lang.reflect.Method getMethod)

Method Detail

isMultipleCardinality

protected static boolean isMultipleCardinality(java.lang.reflect.Method getMethod)

getValueFromBean

public java.util.Set<R> getValueFromBean(D bean)
                                  throws IllegalBioPAXArgumentException

Returns the value of the bean using the default getMethod. If the value is unknown returns null or an empty set depending on the cardinality.

Parameters:

bean - the object whose property is requested

Returns:

an object as the value

Throws:

IllegalBioPAXArgumentException

isUnknown

public boolean isUnknown(java.lang.Object value)

Checks if the value is unkown. In this context a value is regarded to be unknown if it is null (unset).

Parameters:

value - the value to be checked

Returns:

true if the value is unknown

getDomain

public java.lang.Class<D> getDomain()

Returns the domain of the property.

Specified by:

getDomain in interface PropertyAccessor<D extends BioPAXElement,R>

Returns:

the domain of the editor

getRange

public java.lang.Class<R> getRange()

Returns the range of the editor.

Specified by:

getRange in interface PropertyAccessor<D extends BioPAXElement,R>

Returns:

a class

isMultipleCardinality

public boolean isMultipleCardinality()

Checks if the property to which editor is assigned has multiple cardinality.

Specified by:

isMultipleCardinality in interface PropertyAccessor<D extends BioPAXElement,R>

Returns:

true if editor belongs to a multiple cardinality property.
