Interface PropertiesConditionable<E>

Type Parameters:

E - the extending element type, used for method chaining.

All Known Subinterfaces:

public interface PropertiesConditionable<E>

Indicates that the extending element can have a properties condition.

Properties conditions are modeled as an expression tree using the logical operators and/or/not. For example, a property condition may be "(A and not(B)) or (C and not(B))" where A, B and C are individual properties conditions such as "property 'data_name' not equal to 'network'".

A property condition tree can be built using the property condition builder. When the tree is complete, it can be assigned to the element using the withPropertiesConditions(com.hp.ucmdb.api.topology.ConditionExpression<com.hp.ucmdb.api.topology.CompletePropertyCondition, com.hp.ucmdb.api.topology.PropertiesConditionOperand>) method.

An existing properties condition tree can be be retrieved using the propertiesCondition() method. This method returns null if there are no properties conditions set for the element.

Two 'shortcut' methods, property(String) and property(String, Operator, Object), are available. These methods add the resulting property condition as an "and" to the existing properties condition tree (or create a new tree if none existed yet).

UCMDB 9.0

Method Summary

Modifier and Type	Method	Description
ConditionExpression<CompletePropertyCondition,PropertiesConditionOperand>	propertiesCondition()	Returns the properties condition defined on this element.

IncompletePropertyCondition	property(String propertyName)	Creates an incomplete property condition that, when completed, will be added as an "and" to the property conditions expression tree.
E	property(String propertyName, Operator operator, Object value)	Creates a property condition and adds it as an "and" to the property conditions expression tree.
E	property(String propertyName, Operator operator, Object value, String conditionName)	Creates a property condition and adds it as an "and" to the property conditions expression tree.
E	withPropertiesConditions(ConditionExpression<CompletePropertyCondition,PropertiesConditionOperand> propertiesConditionExpression)	Sets the properties condition of this element to the specified condition.

property

IncompletePropertyCondition property(String propertyName)

Parameters:

propertyName - the property this condition should refer to.

Returns:

an incomplete property condition that needs operator and value to be completed.

property

E property(String propertyName,
 Operator operator,
 Object value)

Parameters:

propertyName - the property name to create the condition on.

operator - the operator to use.

value - the value of the property condition, must be of the "correct" type or assignable. Some operators can recieve null as empty values.

Returns:

the element for method chaining.

Parameters:

propertyName - the property name to create the condition on.

operator - the operator to use.

value - the value of the property condition, must be of the "correct" type or assignable. Some operators can recieve null as empty values.
