ImportSchemaDescriptor

public ImportSchemaDescriptor(String name, String type, List<ImportSchemaDescriptor.ImportColumnDescriptor> columnDescriptors)

Outer class for the ImportSource block.

Parameters:

name - The name to be used in the ImportSource block. This can be used to select a particular set of import details, when a table might be loaded from multiple, different, sources of the same type.

type - Normally CSV or JDBC - the type of the source that will use this ImportSource block.

columnDescriptors - A List of ImportColumn details. (sourceName, formula, etc)

ImportSchemaDescriptor

public ImportSchemaDescriptor(String name, String type, int maxError, String arrayDelimiter, List<ImportSchemaDescriptor.ImportColumnDescriptor> columnDescriptors, List<org.jdom2.Element> unsupportedElements)

Outer class for the ImportSource block.

Parameters:

name - The name to be used in the ImportSource block. This can be used to select a particular set of import details, when a table might be loaded from multiple, different, sources of the same type.

type - Normally CSV or JDBC - the type of the source that will use this ImportSource block.

maxError - max errors permissible during an import (default 0)

arrayDelimiter - delimiter to use when parsing array values (default unspecified)

columnDescriptors - A List of ImportColumn details. (sourceName, formula, etc)

Method Details

findSourceType

public static Class<?> findSourceType(String typeName)

Finds a likely compatible target column class for a passed class name.

Parameters:

typeName - Name of the class to match

Returns:

Class that is a likely compatible match, or throws ClassNotFound if no match can be found.

generateImportSource

public org.jdom2.Document generateImportSource()

generateImportSource

public org.jdom2.Document generateImportSource(boolean intermediate)

generateImportSource

public org.jdom2.Document generateImportSource(String imports, boolean intermediate)

Creates the ImportSource block for a schema file

Parameters:

imports - Any entries for the <Imports> element. This element will be omitted if imports is null

Returns:

a String with the ImportSource block
