All Implemented Interfaces:

Serializable, Comparable<PDFStructureReaderSettings.PDFStructureReadStrategy>

Enclosing class:

PDFStructureReaderSettings

public static enum PDFStructureReaderSettings.PDFStructureReadStrategy
extends Enum<PDFStructureReaderSettings.PDFStructureReadStrategy>

Defines the strategy to be used when reading the PDF structure.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ALWAYS_GENERATE_XREF Always generate the cross reference table, regardless if the original cross reference table had errors or not.
LENIENT_ON_ERROR Use the normal/strict parsing mechanism to read the PDF structure.
STRICT Structural errors might lead to exceptions when loading a document. This is the default / classic behavior.

Method Summary

Modifier and Type	Method and Description
static PDFStructureReaderSettings.PDFStructureReadStrategy	valueOf(String name) Returns the enum constant of this type with the specified name.
static PDFStructureReaderSettings.PDFStructureReadStrategy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

STRICT

public static final PDFStructureReaderSettings.PDFStructureReadStrategy STRICT

Structural errors might lead to exceptions when loading a document.
This is the default / classic behavior.

LENIENT_ON_ERROR

public static final PDFStructureReaderSettings.PDFStructureReadStrategy LENIENT_ON_ERROR

Use the normal/strict parsing mechanism to read the PDF structure. If exceptions occur, try to fix/ignore the error if possible (best effort base).

For erroneous documents, loading time will be increased due to the additional structure parsing in the fallback case.

Documents without errors are loaded with same performance as with mode STRICT.

ALWAYS_GENERATE_XREF

public static final PDFStructureReaderSettings.PDFStructureReadStrategy ALWAYS_GENERATE_XREF

Always generate the cross reference table, regardless if the original cross reference table had errors or not.

Method Detail

values

public static PDFStructureReaderSettings.PDFStructureReadStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PDFStructureReaderSettings.PDFStructureReadStrategy c : PDFStructureReaderSettings.PDFStructureReadStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PDFStructureReaderSettings.PDFStructureReadStrategy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
