All Implemented Interfaces:

Serializable

public class DerivedSchemaElement
extends PrimitiveSchemaElement

Derived schema elements are used in views to define elements that are calculated using data from other sources. It contains a list of queries and a formula to combine the resulting values.

Constructors

Constructor and Description
DerivedSchemaElement() Default constructor
DerivedSchemaElement(DerivedSchemaElement templateSchemaElement) Copy/clone Constructor the parentAsset is passed separately to the template because it is also likely to be being cloned in the same operation and we want the definitions clone to point to the asset clone and not the original asset.

Constructor Detail

DerivedSchemaElement

public DerivedSchemaElement()

Default constructor

DerivedSchemaElement

public DerivedSchemaElement(DerivedSchemaElement templateSchemaElement)

Copy/clone Constructor the parentAsset is passed separately to the template because it is also likely to be being cloned in the same operation and we want the definitions clone to point to the asset clone and not the original asset.

Parameters:

templateSchemaElement - template object to copy.

Method Detail

getFormula

public String getFormula()

Return the formula used to combine the values of the queries. Each query is numbers 0, 1, ... and the formula has placeholders in it to show how the query results are combined.

Returns:

String formula

setFormula

public void setFormula(String formula)

Set up the formula used to combine the values of the queries. Each query is numbers 0, 1, ... and the formula has placeholders in it to show how the query results are combined.

Parameters:

formula - String formula

getQueries

public List<SchemaImplementationQuery> getQueries()

Return the list of queries that are used to create the derived schema element.

Returns:

list of queries

setQueries

public void setQueries(List<SchemaImplementationQuery> queries)

Set up the list of queries that are used to create the derived schema element.

Parameters:

queries - list of queries

cloneSchemaElement

public SchemaElement cloneSchemaElement()

Returns a clone of this object as the abstract SchemaElement class.

Overrides:

cloneSchemaElement in class PrimitiveSchemaElement

Returns:

PrimitiveSchemaElement object

toString

public String toString()

Standard toString method.

Overrides:

toString in class PrimitiveSchemaElement

Returns:

print out of variables in a JSON-style

equals

public boolean equals(Object objectToCompare)

Compare the values of the supplied object with those stored in the current object.

Overrides:

equals in class PrimitiveSchemaElement

Parameters:

objectToCompare - supplied object

Returns:

boolean result of comparison
