Detailed Description

This class contains the parameterized decode functions that decode data (in BER format) from an incoming stream into bdlat types.

Constructor & Destructor Documentation

BerDecoder()

balber::BerDecoder::BerDecoder	(	const BerDecoderOptions *	options = 0,
		bslma::Allocator *	basicAllocator = 0
	)

Construct a decoder object. Optionally specify decoder options. If options is 0, BerDecoderOptions() is used. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used.

~BerDecoder()

balber::BerDecoder::~BerDecoder

(

)

Destroy this object. This destruction has no effect on objects pointed-to by the pointers provided at construction.

Member Function Documentation

decode() [1/2]

template<typename TYPE >

int balber::BerDecoder::decode ( bsl::istream &  stream, TYPE *  variable  )

inline

Decode an object of parameterized TYPE from the specified stream and load the result into the specified modifiable variable. Return 0 on success, and a non-zero value otherwise. If the decoding fails stream will be invalidated.

decode() [2/2]

template<typename TYPE >

int balber::BerDecoder::decode	(	bsl::streambuf *	streamBuf,
		TYPE *	variable
	)

Decode an object of parameterized TYPE from the specified streamBuf and load the result into the specified variable. Return 0 on success, and a non-zero value otherwise.

decoderOptions()

const BerDecoderOptions * balber::BerDecoder::decoderOptions ( ) const

inline

errorSeverity()

BerDecoder::ErrorSeverity balber::BerDecoder::errorSeverity ( ) const

inline

Return the severity of the most severe log or error message encountered during the last call to the decode method. The severity is reset each time decode is called.

loggedMessages()

bslstl::StringRef balber::BerDecoder::loggedMessages ( ) const

inline

Return a string containing any error or trace messages that were logged during the last call to the decode method. The log is reset each time decode is called.

maxDepthExceeded()

bool balber::BerDecoder::maxDepthExceeded ( ) const

inline

numUnknownElementsSkipped()

int balber::BerDecoder::numUnknownElementsSkipped ( ) const

inline

Return the number of unknown elements that were skipped during the previous decoding operation. Note that unknown elements are skipped only if true == options()->skipUnknownElements().

setNumUnknownElementsSkipped()

void balber::BerDecoder::setNumUnknownElementsSkipped ( int  value )

inline

Set the number of unknown elements skipped by the decoder during the current decoding operation to the specified value. The behavior is undefined unless 0 <= value.
