Member Function Documentation

virtual void* ibis::bundle1::columnArray ( uint32_t  ) const
inlinevirtual

Return the pointer to the underlying array used to store the jth column of the bundle.

Reimplemented from ibis::bundle.

virtual ibis::TYPE_T ibis::bundle1::columnType ( uint32_t  ) const
inlinevirtual

Return the type used to store the values of the jth column of the bundle.

Reimplemented from ibis::bundle.

References ibis::UNKNOWN_TYPE.

double ibis::bundle1::getDouble ( uint32_t  i,
uint32_t  j 
) const
virtual

Retrieve the value of i-th row j-th column as a 64-bit floating-point value.

Return the maximal value defined in the class numeric_limits if either i or j is out of bounds.

Reimplemented from ibis::bundle.

float ibis::bundle1::getFloat ( uint32_t  i,
uint32_t  j 
) const
virtual

Retrieve the value of i-th row j-th column as a 32-bit floating-point value.

Return the maximal value defined in the class numeric_limits if wither i or j is out of bounds.

Reimplemented from ibis::bundle.

int32_t ibis::bundle1::getInt ( uint32_t  i,
uint32_t  j 
) const
virtual

Retrieve the value of i-th row j-th column as a 32-bit integer.

Return the maximal value defined in the class numeric_limits if either i or j is out of bounds.

Reimplemented from ibis::bundle.

int64_t ibis::bundle1::getLong ( uint32_t  i,
uint32_t  j 
) const
virtual

Retrieve the value of i-th row j-th column as a 64-bit integer.

Return the maximal value defined in the class numeric_limits if either i or j is out of bounds.

Reimplemented from ibis::bundle.

std::string ibis::bundle1::getString ( uint32_t  i,
uint32_t  j 
) const
virtual

Retrieve the value of i-th row j-th column as a string.

Returns an empty string if either i or j is out of bounds, which can not be distinguished from an actual empty string. This function converts a value to its string representation through std::ostringstream.

Reimplemented from ibis::bundle.

uint32_t ibis::bundle1::getUInt ( uint32_t  i,
uint32_t  j 
) const
virtual

Retrieve the value of i-th row j-th column as a 32-bit unsigned integer.

Return the maximal value defined in the class numeric_limits if either i or j is out of bounds.

Reimplemented from ibis::bundle.

uint64_t ibis::bundle1::getULong ( uint32_t  i,
uint32_t  j 
) const
virtual

Retrieve the value of i-th row j-th column as a 64-bit unsigned integer.

Return the maximal value defined in the class numeric_limits if either i or j is out of bounds.

Reimplemented from ibis::bundle.

void ibis::bundle1::print ( std::ostream &  out) const
virtual

Print the bundle values to the specified output stream.

print out the bundles without RIDs.

Implements ibis::bundle.

Referenced by bundle1().

virtual void ibis::bundle1::reorder ( const char *  )
inlinevirtual

Reorder the values.

Since there is only one column in the bundle, the only valid name that can be passed in is the name of the sole column. Because the bundle is already sorted according to this column, there is nothing to do expect to reverse the order of the values based on the second argument.

Implements ibis::bundle.

long ibis::bundle1::truncate ( uint32_t  keep,
uint32_t  start 
)
virtual

This two-argument version keeps a few records starting at a user-specified row number.

Note that the row number starts with 0, i.e., the first row has the row number 0.

Implements ibis::bundle.
