Detailed Description

This class provides input methods to unexternalize values, and C-style arrays of values, of fundamental types from their byte representations. Each input method also verifies the input value type. By default, if invalid data is detected, error messages are displayed on stdout; this error reporting may be disabled via the setQuiet method. Note that attempting to read beyond the end of a stream will automatically invalidate the stream. See the bslx package-level documentation for the definition of the BDEX InStream protocol.

See Component bslx_testinstream


Constructor & Destructor Documentation

bslx::TestInStream::TestInStream (  )  [explicit]

Create an empty test input stream. Note that the constructed object is useless until a buffer is set with the reset method.

bslx::TestInStream::TestInStream ( const char *  buffer,
bsl::size_t  numBytes 
)

Create a test input stream containing the specified initial numBytes from the specified buffer. The behavior is undefined unless 0 == numBytes if 0 == buffer.

bslx::TestInStream::TestInStream ( const bslstl::StringRef srcData  )  [explicit]

Create a test input stream containing the specified srcData.

bslx::TestInStream::~TestInStream (  ) 

Destroy this test input stream.


Member Function Documentation

TestInStream& bslx::TestInStream::getLength ( int &  variable  ) 

If required, throw a TestInStreamException (see throwExceptionIfInputLimitExhausted); otherwise, consume the 8-bit unsigned integer type code, verify the type of the next value in this stream, consume that 8-bit unsigned integer or 32-bit signed integer value representing a length (see the bslx package-level documentation) into the specified variable if its type is appropriate, update the cursor location, and return a reference to this stream. Consume an 8-bit unsigned integer if the most significant bit of this byte is 0, otherwise consume a 32-bit signed integer and set the most significant bit to zero in the resultant variable. If the type is incorrect, then this stream is marked invalid and the value of variable is unchanged. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of variable is undefined.

TestInStream& bslx::TestInStream::getVersion ( int &  variable  ) 

If required, throw a TestInStreamException (see throwExceptionIfInputLimitExhausted); otherwise, consume the 8-bit unsigned integer type code, verify the type of the next value in this stream, consume that 8-bit unsigned integer value representing a version (see the bslx package-level documentation) into the specified variable if its type is appropriate, update the cursor location, and return a reference to this stream. If the type is incorrect, then this stream is marked invalid and the value of variable is unchanged. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of variable is undefined.

void bslx::TestInStream::invalidate (  ) 

Put this input stream in an invalid state. This function has no effect if this stream is already invalid. Note that this function should be called whenever a value extracted from this stream is determined to be invalid, inconsistent, or otherwise incorrect.

void bslx::TestInStream::reset (  ) 

Set the index of the next byte to be extracted from this stream to 0 (i.e., the beginning of the stream) and validate this stream if it is currently invalid.

void bslx::TestInStream::reset ( const char *  buffer,
bsl::size_t  numBytes 
)

Reset this stream to extract from the specified buffer containing the specified numBytes, set the index of the next byte to be extracted to 0 (i.e., the beginning of the stream), and validate this stream if it is currently invalid. The behavior is undefined unless 0 == numBytes if 0 == buffer.

void bslx::TestInStream::reset ( const bslstl::StringRef srcData  ) 

Reset this stream to extract from the specified srcData, set the index of the next byte to be extracted to 0 (i.e., the beginning of the stream), and validate this stream if it is currently invalid.

void bslx::TestInStream::seek ( bsl::size_t  offset  ) 

Set the index of the next byte to be extracted from this stream to the specified offset from the beginning of the stream, and validate this stream if it is currently invalid. The behavior is undefined unless offset <= length().

void bslx::TestInStream::setInputLimit ( int  limit  ) 

Set the number of input operations allowed on this stream to the specified limit before an exception is thrown. If limit is less than 0, no exception is to be thrown. By default, no exception is scheduled.

void bslx::TestInStream::setQuiet ( bool  flagValue  ) 

Set the quiet mode for this test stream to the specified (boolean) flagValue. If flagValue is true, then quiet mode is turned ON and no error messages will be written to standard output. If flagValue is false, then quiet mode is turned OFF. Note that quiet mode is turned OFF by default.

If the type is incorrect, then this stream is marked invalid and the value of variables is unchanged. If this stream is initially invalid, this operation has no effect. If this function otherwise fails to extract a valid value, this stream is marked invalid and the value of variables is undefined.

bslx::TestInStream::operator const void * (  )  const

Return a non-zero value if this stream is valid, and 0 otherwise. An invalid stream is a stream for which an input operation was detected to have failed.

bsl::size_t bslx::TestInStream::cursor (  )  const

Return the index of the next byte to be extracted from this stream.

const char* bslx::TestInStream::data (  )  const

Return the address of the contiguous, non-modifiable external memory buffer of this stream. The behavior of accessing elements outside the range [ data() .. data() + (length() - 1) ] is undefined.

int bslx::TestInStream::inputLimit (  )  const

Return the current number of input requests left before an exception is thrown. A negative value indicates that no exception is scheduled.

bool bslx::TestInStream::isEmpty (  )  const

Return true if this stream is empty, and false otherwise. Note that this function enables higher-level types to verify that, after successfully reading all expected data, no data remains.

bool bslx::TestInStream::isQuiet (  )  const

Return true if this stream's quiet mode is ON, and false otherwise.

bool bslx::TestInStream::isValid (  )  const

Return true if this stream is valid, and false otherwise. An invalid stream is a stream in which insufficient or invalid data was detected during an extraction operation. Note that an empty stream will be valid unless an extraction attempt or explicit invalidation causes it to be otherwise.

bsl::size_t bslx::TestInStream::length (  )  const

Return the total number of bytes stored in the external memory buffer.
