Method Detail

initialParse

protected void initialParse()
                     throws java.io.IOException

The initial parse will first parse only the trailer, the xrefstart and all xref tables to have a pointer (offset) to all the pdf's objects. It can handle linearized pdfs, which will have an xref at the end pointing to an xref at the beginning of the file. Last the root object is parsed.

Throws:

InvalidPasswordException - If the password is incorrect.

java.io.IOException - If something went wrong.

parse

public PDDocument parse()
                 throws java.io.IOException

This will parse the stream and populate the PDDocument object. This will close the keystore stream when it is done parsing. Lenient mode is active by default.

Returns:

the populated PDDocument

Throws:

InvalidPasswordException - If the password is incorrect.

java.io.IOException - If there is an error reading from the stream or corrupt data is found.

parse

public PDDocument parse(boolean lenient)
                 throws java.io.IOException

This will parse the stream and populate the PDDocument object. This will close the keystore stream when it is done parsing.

Parameters:

lenient - activate leniency if set to true

Returns:

the populated PDDocument

Throws:

InvalidPasswordException - If the password is incorrect.

java.io.IOException - If there is an error reading from the stream or corrupt data is found.

createDocument

protected PDDocument createDocument()
                             throws java.io.IOException

Create the resulting document. Maybe overwritten if the parser uses another class as document.

Returns:

the resulting document

Throws:

java.io.IOException - if the method is called before parsing the document

load

@Deprecated
public static PDDocument load(java.io.File file)
                       throws java.io.IOException

Deprecated.

use Loader.loadPDF(File) instead

Parses a PDF. Unrestricted main memory will be used for buffering PDF streams.

Parameters:

file - file to be loaded

Returns:

loaded document

Throws:

InvalidPasswordException - If the file required a non-empty password.

java.io.IOException - in case of a file reading or parsing error

load

@Deprecated
public static PDDocument load(java.io.File file,
                              java.lang.String password)
                       throws java.io.IOException

Deprecated.

use Loader.loadPDF(File, String) instead

Parses a PDF. Unrestricted main memory will be used for buffering PDF streams.

Parameters:

file - file to be loaded

password - password to be used for decryption

Returns:

loaded document

Throws:

InvalidPasswordException - If the password is incorrect.

java.io.IOException - in case of a file reading or parsing error
