Method Details

setProperty

public void setProperty(String key,
 Object value)

Description copied from class: UnboundBean

Set property key to value.

This implementation calls a write method for the property using JavaBeans introspection.

Specified by:

setProperty in interface BeanInterface

Overrides:

setProperty in class UnboundBean

Parameters:

key - name of the property

value - the value to set the property to

See Also:

• BeanInterface.setProperty(java.lang.String, java.lang.Object)

setIndexedProperty

public void setIndexedProperty(String key,
 int index,
 Object value)

Description copied from class: UnboundBean

Set element at index of property array key to value.

This implementation calls a write method for the indexed property using JavaBeans introspection, and assumes, based on JavaBeans coding patterns, that the write method has the following two parameters in order: index, value.

Specified by:

setIndexedProperty in interface BeanInterface

Overrides:

setIndexedProperty in class UnboundBean

Parameters:

key - name of the property

index - index of the property element to change

value - the value to set the property to

See Also:

• BeanInterface.setIndexedProperty(java.lang.String, int, java.lang.Object)

getIndexedProperty

public Object getIndexedProperty(String key,
 int index)

Description copied from class: UnboundBean

Get value of element at index of property array key.

This implementation calls a read method for the indexed property using JavaBeans introspection, and assumes, based on JavaBeans coding patterns, that the read method has the following parameter: index. Note that this method returns null instead of throwing ArrayIndexOutOfBoundsException if the index is invalid since the Java introspection methods provide no reliable way to get the size of the indexed property.

Specified by:

getIndexedProperty in interface BeanInterface

Overrides:

getIndexedProperty in class UnboundBean

Parameters:

key - name of the property

index - index of the property element to change

Returns:

value of element or null

getProperty

public Object getProperty(String key)

Description copied from class: UnboundBean

Get the value of property key.

If null is a valid (or expected) value for key, you might want to use UnboundBean.hasProperty(java.lang.String) to test that the property exists.

Specified by:

getProperty in interface BeanInterface

Overrides:

getProperty in class UnboundBean

Parameters:

key - name of the property

Returns:

value of key or null.

See Also:

• BeanInterface.getProperty(java.lang.String)

hasProperty

public boolean hasProperty(String key)

Description copied from class: UnboundBean

Test if a property exists.

Specified by:

hasProperty in interface BeanInterface

Overrides:

hasProperty in class UnboundBean

Parameters:

key - name of the property

Returns:

true if property exists

See Also:

• BeanInterface.hasProperty(java.lang.String)

hasIndexedProperty

public boolean hasIndexedProperty(String key)

Description copied from interface: BeanInterface

Test that a property exists and is indexed.

NOTE Implementing method must not call Bean.hasIndexedProperty(), as doing so will cause a stack overflow. Implementing methods may call Beans.hasIntrospectedIndexedProperty() instead.

Specified by:

hasIndexedProperty in interface BeanInterface

Overrides:

hasIndexedProperty in class UnboundBean

Parameters:

key - name of the property

Returns:

true is property key exists and is indexed

getPropertyNames

public Set<String> getPropertyNames()

Description copied from class: UnboundBean

Return a list of property names.

Specified by:

getPropertyNames in interface BeanInterface

Overrides:

getPropertyNames in class UnboundBean

Returns:

a Set of names

• BeanInterface.getPropertyNames()
