All Implemented Interfaces:

Serializable

public class AssetDerivedSchemaElement
extends AssetPrimitiveSchemaElement

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
AssetDerivedSchemaElement(AssetDescriptor parentAsset, AssetDerivedSchemaElement 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.
AssetDerivedSchemaElement(AssetDescriptor parentAsset, DerivedSchemaElement derivedSchemaElementBean, AssetMeanings assetMeanings, AssetSchemaImplementationQueries queries) Bean constructor with parent asset
AssetDerivedSchemaElement(DerivedSchemaElement derivedSchemaElementBean, AssetMeanings assetMeanings, AssetSchemaImplementationQueries queries) Bean constructor

Method Summary

Constructor Detail

AssetDerivedSchemaElement

public AssetDerivedSchemaElement(DerivedSchemaElement derivedSchemaElementBean,
                                 AssetMeanings assetMeanings,
                                 AssetSchemaImplementationQueries queries)

Bean constructor

Parameters:

derivedSchemaElementBean - bean containing the schema element properties

assetMeanings - iterator for the asset assetMeanings

queries - queries used to create the element

AssetDerivedSchemaElement

public AssetDerivedSchemaElement(AssetDescriptor parentAsset,
                                 DerivedSchemaElement derivedSchemaElementBean,
                                 AssetMeanings assetMeanings,
                                 AssetSchemaImplementationQueries queries)

Bean constructor with parent asset

Parameters:

parentAsset - descriptor for parent asset

derivedSchemaElementBean - bean containing the schema element properties

assetMeanings - iterator for the asset assetMeanings

queries - queries used to create the element

AssetDerivedSchemaElement

public AssetDerivedSchemaElement(AssetDescriptor parentAsset,
                                 AssetDerivedSchemaElement 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:

parentAsset - description of the asset that this schema element is attached to.

templateSchemaElement - template object to copy.

Method Detail

getDerivedSchemaElementBean

protected DerivedSchemaElement getDerivedSchemaElementBean()

Return the bean with all of the properties in it.

Returns:

derived schema element bean

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

getQueries

public AssetSchemaImplementationQueries getQueries()

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

Returns:

SchemaImplementationQueries list of queries

cloneAssetSchemaElement

public AssetSchemaElement cloneAssetSchemaElement(AssetDescriptor parentAsset)

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

Overrides:

cloneAssetSchemaElement in class AssetPrimitiveSchemaElement

Parameters:

parentAsset - description of the asset that this schema element is attached to.

Returns:

PrimitiveSchemaElement object

toString

public String toString()

Standard toString method.

Overrides:

toString in class AssetPrimitiveSchemaElement

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 AssetPrimitiveSchemaElement

Parameters:

objectToCompare - supplied object

Returns:

boolean result of comparison
