Detailed Description

The error handling class of the PoDoFo library.

If a method encounters an error, a PdfError object is thrown as a C++ exception.

This class does not inherit from std::exception.

This class also provides meaningful error descriptions for the error codes which are values of the enum PdfErrorCode, which are all codes PoDoFo uses (except the first and last one).

Parameters

code	the error code of this object
filepath	the file in which the error has occurred. Use the compiler macro FILE to initialize the field.
line	the line in which the error has occurred. Use the compiler macro LINE to initialize the field.
information	additional information on this error

PdfError() [2/2]

PoDoFo::PdfError::PdfError ( const PdfError &  rhs )

default

Copy constructor.

Parameters

rhs	copy the contents of rhs into this object

Member Function Documentation

ErrorMessage()

string_view PdfError::ErrorMessage ( PdfErrorCode  code )

static

Get the error message for a certain error code.

Returns

the error message or nullptr if no error message for the specified error code is available.

ErrorName()

string_view PdfError::ErrorName ( PdfErrorCode  code )

static

Get the name for a certain error code.

Returns

the name or nullptr if no name for the specified error code is available.

GetCallStack()

const PdErrorInfoStack& PoDoFo::PdfError::GetCallStack ( ) const

inline

Get access to the internal callstack of this error.

Returns

the callstack deque of PdfErrorInfo objects.

GetCode()

PdfErrorCode PoDoFo::PdfError::GetCode ( ) const

inline

Return the error code of this object.

Returns

the error code of this object

operator!=()

bool PdfError::operator!=

(

PdfErrorCode

code

)

Compares this PdfError object with an error code.

Parameters

code	an error code (value of the enum PdfErrorCode)

Returns

true if this object has a different error code.

operator=()

PdfError& PoDoFo::PdfError::operator= ( const PdfError &  rhs )

default

Assignment operator.

Parameters

rhs	another PdfError object

Returns

this object

operator==()

bool PdfError::operator==

(

PdfErrorCode

code

)

Compares this PdfError object with an error code.

Parameters

code	an error code (value of the enum PdfErrorCode)

Returns
