Method Details

getType

public ComplexType getType()

Description copied from interface: Property

The type of the property.

The type contains information about the value or content of the property such as its java class.

This value is also available via getDescriptor().getType().

Specified by:

getType in interface Attribute

Specified by:

getType in interface ComplexAttribute

Specified by:

getType in interface Property

Overrides:

getType in class AttributeImpl

Returns:

The property type.

See Also:

• Property.getType()

getValue

public Collection<? extends Property> getValue()

Description copied from interface: Property

The value or content of the property.

The class of this object is defined by getType().getBinding().

This value may be null. In this case getDescriptor().isNillable() would be true.

Specified by:

getValue in interface ComplexAttribute

Specified by:

getValue in interface Property

Overrides:

getValue in class PropertyImpl

Returns:

The value of the property.

getProperties

public Collection<Property> getProperties()

Description copied from interface: ComplexAttribute

Complete collection of properties.

This method is a convenience method for calling (Collection) getValue().

Specified by:

getProperties in interface ComplexAttribute

Returns:

The complete collection of properties.

properties

protected List<Property> properties()

Internal helper method for getting at the properties without wrapping in unmodifiable collection.

getProperties

public Collection<Property> getProperties(Name name)

Description copied from interface: ComplexAttribute

Returns a subset of the properties of the complex attribute which match the specified name.

The name parameter is matched against each contained Property.getName(), those that are equal are returned.

Specified by:

getProperties in interface ComplexAttribute

Parameters:

name - The name of the properties to return.

Returns:

The collection of properties which match the specified name, or an empty collection if no such properties match.

findLast

public Optional<Property> findLast(Name name)

Returns:

the first property in getProperties() reverse order whose name equals the given name

findAll

public Stream<Property> findAll(Predicate<? super Property> predicate)

Returns:

all properties that match the provided predicate, may be empty, never null

find

public Optional<Property> find(Predicate<? super Property> predicate)

Returns:

the first property that matches the provided predicate, or Optional.empty()

getProperties

public Collection<Property> getProperties(String name)

Description copied from interface: ComplexAttribute

Returns a subset of the properties of the complex attribute which match the specified name.

This method is a convenience for ComplexAttribute.getProperties(Name) in which Name.getNamespaceURI() is null.

Note: Special care should be taken when using this method in the case that two properties with the same local name but different namespace uri exist. For this reason using ComplexAttribute.getProperties(Name) is safer.

Specified by:

getProperties in interface ComplexAttribute

Parameters:

name - The local name of the properties to return.

Returns:

The collection of properties which match the specified name, or an empty collection if no such properties match.

See Also:

• ComplexAttribute.getProperties(Name)

getProperty

public Property getProperty(Name name)

Description copied from interface: ComplexAttribute

Returns single property of the complex attribute which matches the specified name.

Note: This method is a convenience and care should be taken when calling it if more then a single property matches name. In such a case the first encountered property in which Property.getName() is equal to name is returned, and no order is guaranteed.

This method is a safe convenience for: getProperties(name).iterator().next().

In the event that no property matches the specified name null is returned.

Specified by:

getProperty in interface ComplexAttribute

Parameters:

name - The name of the property to return.

Returns:

The property matching the specified name, or null.

getProperty

public Property getProperty(String name)

Description copied from interface: ComplexAttribute

Returns single property of the complex attribute which matches the specified name.

This method is a convenience for ComplexAttribute.getProperty(Name) in which Name.getNamespaceURI() is null.

Note: This method is a convenience and care should be taken when calling it if more then a single property matches name. In such a case the first encountered property in which Property.getName() is matches name is returned, and no order is guaranteed.

Note: Special care should be taken when using this method in the case that two properties with the same local name but different namespace uri exist. For this reason using ComplexAttribute.getProperties(Name) is safer.

Specified by:

getProperty in interface ComplexAttribute

Parameters:

name - The local name of the property to return.

Returns:

The property matching the specified name, or null.

setValue

public void setValue(Object newValue)
              throws IllegalArgumentException,
IllegalStateException

Description copied from class: AttributeImpl

Override of setValue to convert the newValue to specified type if need be.

Specified by:

setValue in interface Property

Overrides:

setValue in class AttributeImpl

Parameters:

newValue - The new value of the property.

Throws:

IllegalArgumentException

IllegalStateException

setValue

public void setValue(Collection<Property> newValue)

Description copied from interface: ComplexAttribute

Sets the contained properties of the complex attribute.

The values should match the structure defined by getDescriptor().

Specified by:

setValue in interface ComplexAttribute

addValue

public void addValue(Property value)

Appends a property to this attribute's property list without incurring in unnecessary object allocation such as safe-copying the values list as in setValue(Collection)
