All Implemented Interfaces

Serializable

public class Property
extends ContentEntity

Property is a name value pair, with the name being unique relative to the Node and the value is an Array of Value objects.

The Value object can represent either BinaryValue, Boolean, Calendar, Double, Long, String, or ID (link property -- link to a node) values.

If the property is multivalued it may contain 0..n Values. If it is not multivalued it may contain 0..1.

A Property is part of a Node and its shape is defined by a PropertyDefinition with the same name in it's Node's ObjectClass.

A property may represent both the content and meta-content for a Node.

Link properties have some special restrictions. They can only be created in extended repositories. A node must exist at the specified ID when the link property is created or saved.

Constants Summary

NESTED

public static final int NESTED

A Constant to define if the Property is a nested type. If constructing a Property of nested type, the Value should be of a nested type.

For example: Property myProperty = new Property("myNestedProp", myNestedValue); The parameter "myNestedProp" is the name of the nested Property, which nests the properties of the ObjectClass that it represents. The parameter myNestedValue is an array of Property objects. These Property objects contain the properties and values from the nested ObjectClass.

public static final String NESTED_DELIMITER

The delimiter used for nested property names.

Constructor Detail

Property

public Property(String name)

Constructor with just the name. This may be used when creating a property whose type is defined by the PropertyDefinition.

Parameters

name - - the unique name (relative to the Node) of this Property.

Property

public Property(String name,
                Value value)

Constructor for a single value without type. After using this constructor a call to getValue will return the value passed in. A call to getValues will return an array of size one with this value at [0]. This may be used when creating a property whose type is defined by the PropertyDefinition.

Parameters

name - - the unique name (relative to the Node) of this Property.

value - - the value for this Property.

Property

public Property(String name,
                Value[] values)

Constructor for multiple values without type. This may be used when creating a property whose type is defined by the PropertyDefinition.

Parameters

name - - the unique name (relative to the Node) of this Property.

values - - the array of values for this Property.

Property

public Property(ID id,
                String name,
                int type,
                Value[] values)

Constructor with all values.

Parameters

id - - the id for this Property.

name - - the unique name (relative to the Node) of this Property.

type - - the type of this Property.

values - - the array of values for this Property.

Method Detail

getName

public String getName()

Returns the name of the Property. This name is unique to the Node. If this is a nested type, the name will reflect the nested hierarchy with NESTED_DELIMITER between each parent and child property name. The delimiter is not valid for use within the actual name, only to seperate the parent/child names.

setName

public void setName(String name)

Sets the name of the property that is unique to the Node. If this is a nested type, the name will reflect the nested hierarchy with NESTED_DELIMITER between each parent and child property name. The delimiter is not valid for use within the actual name, only to seperate the parent/child names.

getIndexedName

public String getIndexedName()

Returns the indexed name of the Property. This name is unique to the Node. This name is only used for multivalued nested types, to show the indexed order and be able to uniquely identify each property, ie person.addresses[0].city, where addresses is the multivalued nested type. The indexedName will be populated when the Property is retrieved from the DB, which means that it will not exist until after it is persisted for the first time.

getType

public int getType()

Gets the type of the Property.

setType

public void setType(int type)

Sets the type of the Property.

getValue

public Value getValue()

Gets the first Value. Useful for single value Property.

getValues

public Value[] getValues()

Returns an Array of the Property's Values.

setValues

public void setValues(Value[] values)

Sets the properties values.

setValue

public void setValue(Value value)

Sets a Value for the Property.

addValue

public void addValue(Value value)

Add a value to the current list of values

Parameters

value -

hasValue

public boolean hasValue()

Returns true if getValues() contains an instance of Value in the array.

valuesEqual

public boolean valuesEqual(Value[] otherValues)

Compares property's values against a value array. Returns true if they are equal. This method will not return the correct value if the property value is binary.

toString

public String toString()

Returns the Property name and values as a String in the format name: value1, value2, value3

Overrides:

toString in class ContentEntity

toPrintString

public String toPrintString()

Returns the Property name and values as a String in the format name: value1, value2, value3, along with the property id.

isDirty

public boolean isDirty()

Returns true when the value(s) for this property have change since construction.

Returns

true if dirty.

clone

public Object clone()
             throws CloneNotSupportedException

Clones a property and its values. Note that binary value streams of propert values are not cloned, but merely copied.

Overrides:

clone in class Object

Returns

A clone of the property.

Throws

CloneNotSupportedException - If the clone fails.
