DebugInfo
DIHCacheSupport
DIHProperties	Implementations write out properties about the last data import for use by the next import.
DIHWriterBase
DocBuilder	DocBuilder is responsible for creating Solr documents out of the given configuration.
DocBuilder.Statistics
EntityProcessor	An instance of entity processor serves an entity.
EntityProcessorBase	Base class for all implementations of EntityProcessor
EntityProcessorWrapper	A Wrapper over EntityProcessor instance which performs transforms and handles multi-row outputs correctly.
Evaluator	Pluggable functions for resolving variables
FieldReaderDataSource	This can be useful for users who have a DB field containing xml and wish to use a nested XPathEntityProcessor The datasouce may be configured as follows <datasource name="f1" type="FieldReaderDataSource" /> The enity which uses this datasource must keep the url value as the variable name url="field-name" The fieldname must be resolvable from VariableResolver This may be used with any EntityProcessor which uses a DataSource<Reader> eg: XPathEntityProcessor Supports String, BLOB, CLOB data types and there is an extra field (in the entity) 'encoding' for BLOB types
FieldStreamDataSource	This can be useful for users who have a DB field containing BLOBs which may be Rich documents The datasouce may be configured as follows <dataSource name="f1" type="FieldStreamDataSource" /> The entity which uses this datasource must keep and attribute dataField The fieldname must be resolvable from VariableResolver This may be used with any EntityProcessor which uses a DataSource<InputStream> eg: TikaEntityProcessor
FileDataSource	A DataSource which reads from local files
FileListEntityProcessor	An EntityProcessor instance which can stream file names found in a given base directory matching patterns and returning rows containing file information.
HTMLStripTransformer	A Transformer implementation which strip off HTML tags using HTMLStripCharFilter This is useful in case you don't need this HTML anyway.
HttpDataSource	Deprecated use URLDataSource instead
JdbcDataSource	A DataSource implementation which can fetch data using JDBC.
LineEntityProcessor	An EntityProcessor instance which can stream lines of text read from a datasource.
LogTransformer	A Transformer implementation which logs messages in a given template format.
MockDataSource	A mock DataSource implementation which can be used for testing.
NumberFormatTransformer	A Transformer instance which can extract numbers out of strings.
PlainTextEntityProcessor	An implementation of EntityProcessor which reads data from a url/file and give out a row which contains one String value.
RegexTransformer	A Transformer implementation which uses Regular Expressions to extract, split and replace data in fields.
RequestInfo
ScriptTransformer	A Transformer instance capable of executing functions written in scripting languages as a Transformer instance.
SimplePropertiesWriter	Writes properties using Properties.store(java.io.Writer, java.lang.String) .
SolrEntityProcessor	An implementation of EntityProcessor which fetches values from a separate Solr implementation using the SolrJ client library.
SolrQueryEscapingEvaluator
SolrWriter	Writes documents to SOLR.
SortedMapBackedCache
SqlEntityProcessor	An EntityProcessor instance which provides support for reading from databases.
SqlEscapingEvaluator	Escapes values in SQL queries.
TemplateTransformer	A Transformer which can put values into a column by resolving an expression containing other columns
Transformer	Use this API to implement a custom transformer for any given entity
URLDataSource	A data source implementation which can be used to read character files using HTTP.
UrlEvaluator	Escapes reserved characters in Solr queries
VariableResolver	A set of nested maps that can resolve variables by namespaces.
XPathEntityProcessor	An implementation of EntityProcessor which uses a streaming xpath parser to extract values out of XML documents.
XPathRecordReader	A streaming xpath parser which uses StAX for XML parsing.
ZKPropertiesWriter	A SolrCloud-friendly extension of SimplePropertiesWriter.
