  Methods in org.apache.uima.cas.impl with parameters of type AllowPreexistingFS
  Modifier and Type
  Method
  Description
  `void`
  BinaryCasSerDes6.`deserialize(InputStream istream, AllowPreexistingFS aAllowPreexistingFS)`
  Version used by uima-as to read delta cas from remote parallel steps
  `static void`
  XmiCasDeserializer.`deserialize(InputStream aStream, CAS aCAS, boolean aLenient, XmiSerializationSharedData aSharedData, int aMergePoint, AllowPreexistingFS allowPreexistingFS)`
  Deserializes a CAS from XMI.
  `void`
  BinaryCasSerDes6.`deserializeAfterVersion(DataInputStream istream, boolean aIsDelta, AllowPreexistingFS aAllowPreexistingFS)`
  `static BinaryCasSerDes6`
  Serialization.`deserializeCAS(CAS cas, InputStream istream, TypeSystem tgtTypeSystem, BinaryCasSerDes6.ReuseInfo reuseInfo, AllowPreexistingFS allowPreexisting)`
  Deserialize a CAS, in various binary formats, into an existing CAS Note: this form supports deserializing the following binary representations: - compressed, type filtering (form 6), delta and not-delta.
  `DefaultHandler`
  XmiCasDeserializer.`getXmiCasHandler(CAS cas, boolean lenient, XmiSerializationSharedData sharedData, int mergePoint, AllowPreexistingFS allow)`
  Create a default handler for deserializing a CAS from XMI.
  `SerialFormat`
  BinaryCasSerDes.`reinit(CommonSerDes.Header h, InputStream istream, CASMgrSerializer casMgrSerializer, CasLoadMode casLoadMode, BinaryCasSerDes6 f6, AllowPreexistingFS allowPreexistingFS, TypeSystemImpl ts)`
  Deserialize a binary input stream, after reading the header, and optionally an externally provided type system and index spec used in compressed form 6 serialization previously This reads in and deserializes CAS data from a stream.
