Interface Summary

Interface	Description
Cache<K,V>
ContentStream
ExecutorUtil.InheritableThreadLocalProvider	Any class which wants to carry forward the threadlocal values to the threads run by threadpools must implement this interface and the implementation should be registered here
JavaBinCodec.ObjectResolver	Allows extension of JavaBinCodec to support serialization of arbitrary data types.
JavaBinCodec.WritableDocFields
JsonRecordReader.Handler	Implement this interface to stream records as and when one is found.
RetryUtil.BooleanRetryCmd
RetryUtil.RetryCmd
ValidatingJsonMap.PredicateWithErrMsg<T>

Class Summary

Class	Description
Base64	Static methods for translating Base64 encoded strings to byte arrays and vice-versa.
ByteUtils
CommandOperation
ContentStreamBase	Three concrete implementations for ContentStream - one for File/URL/String
ContentStreamBase.ByteArrayStream	Construct a ContentStream from a File
ContentStreamBase.FileStream	Construct a ContentStream from a File
ContentStreamBase.StringStream	Construct a ContentStream from a String
ContentStreamBase.URLStream	Construct a ContentStream from a URL This uses a URLConnection to get the content stream
DataInputInputStream	An abstract DataInput that extends InputStream
ExecutorUtil
ExecutorUtil.MDCAwareThreadPoolExecutor
FastInputStream	Single threaded buffered InputStream Internal Solr use only, subject to change.
FastOutputStream	Single threaded buffered OutputStream Internal Solr use only, subject to change.
Hash	Fast, well distributed, cross-platform hash functions.
Hash.LongPair	128 bits of state
IOUtils
JavaBinCodec	Defines a space-efficient serialization/deserialization format for transferring data.
JavaBinCodec.StringBytes
JavaBinCodec.StringCache
JsonRecordReader	A Streaming parser for json to emit one record at a time.
JsonSchemaValidator	A very basic and lightweight json schema parsing and data validation tool.
MapBackedCache<K,V>
NamedList<T>	A simple container class for modeling an ordered list of name/value pairs.
NamedList.NamedListEntry<T>	Helper class implementing Map.Entry<String, T> to store the key-value relationship in NamedList (the keys of which are String-s)
ObjectReleaseTracker
Pair<T1,T2>
PathTrie<T>	A utility class to efficiently parse/store/lookup hierarchical paths which are templatized like /collections/{collection}/shards/{shard}/{replica}
RetryUtil
SimpleOrderedMap<T>	SimpleOrderedMap is a NamedList where access by key is more important than maintaining order when it comes to representing the held data in other forms, as ResponseWriters normally do.
SolrjNamedThreadFactory
StrUtils
Template
URLUtil
Utils
ValidatingJsonMap
XML
XMLErrorLogger

Annotation Types Summary

Annotation Type	Description
SuppressForbidden	Annotation to suppress forbidden-apis errors inside a whole class, a method, or a field.
