Enum Constant Summary

Enum Constants

Enum Constant	Description
ALL	Create a unioned field for every field contributed by every member dataSource.
INTERSECT	Only create a unioned field where all of the member dataSources have a field with the same name and data type
MATCHING	Create a unioned field where at least two of the member dataSources have a field with the same name and data type.

Method Summary

Modifier and Type	Method	Description

Enum Constant Details

INTERSECT

public static final UnionFieldsStrategy INTERSECT

Only create a unioned field where all of the member dataSources have a field with the same name and data type

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "intersect".

MATCHING

public static final UnionFieldsStrategy MATCHING

Create a unioned field where at least two of the member dataSources have a field with the same name and data type. Any member dataSources that do not have the field will contribute a null value for that field in the unioned dataset

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "matching".

ALL

public static final UnionFieldsStrategy ALL

Create a unioned field for every field contributed by every member dataSource. Where there are matching fields on other dataSource(s), we will union the fields as described for "matching". Where a field only exists on one dataSource, all other dataSources will contribute null for that field in the unioned dataset

If this enumerated value is used in a Component XML file or server-side DataSource descriptor (.ds.xml file), use the value "all".

Method Details

values

public static UnionFieldsStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static UnionFieldsStrategy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getValue

public String getValue()

Specified by:

getValue in interface ValueEnum
