AccessPermission (PDFBox reactor 2.0.4 API)

java.lang.Object
- org.apache.pdfbox.pdmodel.encryption.AccessPermission

```
public class AccessPermission
extends Object
```
This class represents the access permissions to a document. These permissions are specified in the PDF format specifications, they include:
- print the document
- modify the content of the document
- copy or extract content of the document
- add or modify annotations
- fill in interactive form fields
- extract text and graphics for accessibility to visually impaired people
- assemble the document
- print in degraded quality
This class can be used to protect a document by assigning access permissions to recipients. In this case, it must be used with a specific ProtectionPolicy. When a document is decrypted, it has a currentAccessPermission property which is the access permissions granted to the user who decrypted the document.

    A standard owner access permission set.
  - getPermissionBytesForPublicKey
```
public int getPermissionBytesForPublicKey()
```
    This returns an integer representing the access permissions. This integer can be used for public key encryption. This format is not documented in the PDF specifications but is necessary for compatibility with Adobe Acrobat and Adobe Reader.
    
    Returns:
    the integer representing access permissions
  - getPermissionBytes
```
public int getPermissionBytes()
```
    The returns an integer representing the access permissions. This integer can be used for standard PDF encryption as specified in the PDF specifications.

    the integer representing the access permissions
  - canPrint
```
public boolean canPrint()
```
    This will tell if the user can print.
    
    Returns:
    true If supplied with the user password they are allowed to print.
  - setCanPrint
```
public void setCanPrint(boolean allowPrinting)
```
    Set if the user can print.
    This method will have no effect if the object is in read only mode.
    
    Parameters:
    allowPrinting - A boolean determining if the user can print.
  - canModify
```
public boolean canModify()
```
    This will tell if the user can modify contents of the document.

public void setCanModify(boolean allowModifications)
```
    Set if the user can modify the document.
    This method will have no effect if the object is in read only mode.
    
    Parameters:
    allowModifications - A boolean determining if the user can modify the document.
  - canExtractContent
```
public boolean canExtractContent()
```
    This will tell if the user can extract text and images from the PDF document.

  - canModifyAnnotations
```
public boolean canModifyAnnotations()
```
    This will tell if the user can add or modify text annotations and fill in interactive forms fields and, if canModify() returns true, create or modify interactive form fields (including signature fields). Note that if canFillInForm() returns true, it is still possible to fill in interactive forms (including signature fields) even if this method here returns false.
    
    Returns:
    true If supplied with the user password they are allowed to modify annotations.
  - setCanModifyAnnotations
```
public void setCanModifyAnnotations(boolean allowAnnotationModification)
```
    Set if the user can add or modify text annotations and fill in interactive forms fields and, if canModify() returns true, create or modify interactive form fields (including signature fields). Note that if canFillInForm() returns true, it is still possible to fill in interactive forms (including signature fields) even the parameter here is false.
    This method will have no effect if the object is in read only mode.
    
    Parameters:
    allowAnnotationModification - A boolean determining the new setting.
  - canFillInForm

    Set if the user can fill in interactive form fields (including signature fields) even if canModifyAnnotations() returns false. Therefore, if you want to prevent a user from filling in interactive form fields, you need to call setCanModifyAnnotations(false) as well.
    This method will have no effect if the object is in read only mode.
    
    Parameters:
    allowFillingInForm - A boolean determining if the user can fill in interactive forms.
