XReferenceEntry

All Superinterfaces:

java.lang.Comparable<XReferenceEntry>

All Known Implementing Classes:

AbstractXReference, FreeXReference, NormalXReference, ObjectStreamXReference
```
public interface XReferenceEntry
extends java.lang.Comparable<XReferenceEntry>
```
An implementing class represents an entry, as it can be found in a PDF's crossreference stream (PDFXRefStream). Such an entry shall locate a PDF object/resource in a PDF document.

- Method Detail
  - getType
```
XReferenceType getType()
```
    Returns the XReferenceType of this crossreference stream entry.
    
    Returns:
    
    The XReferenceType of this crossreference stream entry.
  - getReferencedKey
```
COSObjectKey getReferencedKey()
```
    Returns the COSObjectKey of the object, that is described by this crossreference stream entry.
    
    Returns:
    
    The COSObjectKey of the object, that is described by this crossreference stream entry.
  - getFirstColumnValue
```
long getFirstColumnValue()
```
    Returns the value for the first column of the crossreference stream entry. (The numeric representation of this entry's XReferenceType.)
    
    Returns:
    
    The value for the first column of the crossreference stream entry.
  - getSecondColumnValue
```
long getSecondColumnValue()
```
    Returns the value for the second column of the crossreference stream entry. (It's meaning depends on the XReferenceType of this entry.)
    
    Returns:
    
    The value for the second column of the crossreference stream entry.
  - getThirdColumnValue
```
long getThirdColumnValue()
```
    Returns the value for the third column of the crossreference stream entry. (It's meaning depends on the XReferenceType of this entry.)
    
    Returns:
    
    The value for the third column of the crossreference stream entry.
