```
public class CRAMCompressionRecord
extends Object
```
A CRAMRecord represents a SAMRecord that has been transformed to CRAM-style representation. This includes representing read bases as reference-relative read features, and representation of quality scores, tags, and BAM and CRAM flags.

Method Detail
- toSAMRecord
```
public SAMRecord toSAMRecord(SAMFileHeader samFileHeader)
```
  Create a SAMRecord from the CRAMRecord.
  
  Parameters:
  
  samFileHeader - SAMFileHeader
  
  Returns:
  
  a SAMRecord
- assignReadName
```
public void assignReadName()
```
- isNormalized
```
public boolean isNormalized()
```
  When a CRAM record is read from a CRAM stream, it is "raw" in that the record's read bases, quality scores, and mate graph are not stored directly as part of the record. These values must be resolved through the separate process of normalization, which is performed at Slice granularity (all records in a Slice are normalized at the same time). (see Slice#normalizeCRAMRecords(List, CRAMReferenceRegion, SubstitutionMatrix)).
  
  Returns:
  
  true if this record is normalized
- resolveQualityScores
```
public void resolveQualityScores()
```
  Resolve the quality scores for this CRAM record based on preserved scores, read features and flags.
- restoreReadBases
```
public void restoreReadBases(byte[] referenceBases,
                             int zeroBasedReferenceOffset,
                             SubstitutionMatrix substitutionMatrix)
```
  Parameters:
  
  referenceBases - reference bases for this reference, if one is required (may be null for records with RR=false in the compression header)
  
  zeroBasedReferenceOffset - zero-based reference offset of the first base in referenceBases
  
  substitutionMatrix - substitution matrix
- restoreMateInfo
```
public void restoreMateInfo()
```
- setToDetachedState
```
public void setToDetachedState()
```
- isPlaced
```
public boolean isPlaced()
```
  Determine is read is "placed". For consistency with the rest of htsjdk, this only consults the alignmentStart (placed reads should also have a valid reference index, and unplaced reads should be unmapped; those two abberant conditions are logged as warnings).
  
  Returns:
  
  true if the record is placed

  Does this record have the mapped flag set? This is independent of placement/alignment status. Unmapped records may be stored in the same Slices and Containers as mapped records if they are placed.
