Detailed Description

The type for variable-length multidimensional arrays.

Note: This class was not designed to achieve performance, since it maps a vector of positions to one abstract data. This class is only a container to be used by database drivers. If you need a high performance array class with matrix operations, see the Matrix module. To access the data, you must define a vector of positions, where each dimension in the vector corresponds to the respective dimension in the array.

Member Function Documentation

te::dt::AbstractData * te::dt::Array::clone ( ) const

virtual

It creates a new clone of the array.

Returns: A new clone of the array. The caller will take its ownership.

Definition at line 136 of file Array.cpp.

te::dt::AbstractData * te::dt::Array::getData ( const std::vector< std::size_t > & i )

Returns data from specified position.

Parameters

i	The position in the array to get data (d1, d2, ... dn).

Returns: The data from specified position.

Definition at line 122 of file Array.cpp.

References te::common::GetPValue().

std::size_t te::dt::Array::getDimension ( ) const

Returns the numbe of dimensions of the array.

Definition at line 91 of file Array.cpp.

std::size_t te::dt::Array::getDimensionSize ( std::size_t i ) const

Gets the number of elements in the i-th dimension.

Parameters

i	The dimension index.

Returns: The number of elements in the i-th dimension.

Definition at line 101 of file Array.cpp.

int te::dt::Array::getElementsTypeCode ( )

Returns the data type of the elements of the array.

Note: The attribute types are listed in terralib/datatype/DataTypes.h

Definition at line 96 of file Array.cpp.

int te::dt::Array::getTypeCode ( ) const

inlinevirtual

Returns the type code for array data: ARRAY_TYPE.

Implements te::dt::AbstractData.

Definition at line 144 of file Array.h.

References te::dt::ARRAY_TYPE.

void te::dt::Array::insert	(	te::dt::AbstractData *	data,
		const std::vector< std::size_t > &	pos
	)

Inserts data into specified position.

Parameters

data	The data to be inserted.
pos	The position in the array to insert data (d1, d2, ... dn).

Definition at line 108 of file Array.cpp.

te::dt::Array & te::dt::Array::operator= ( const Array & rhs )

Assignment operator.

Parameters

rhs	The right-hand-side instance.

Returns: A reference to this array.

Definition at line 59 of file Array.cpp.

References te::common::FreeContents(), m_data, m_dimension, m_dimensionSizes, and m_type.

te::dt::AbstractData & te::dt::Array::operator[] ( const std::vector< std::size_t > & i )

Access data in i index.

Parameters

i	The data index, a vector of std::size_t.

Warning: The caller is reponsible for providing a valid index.

Returns: A reference to the i-th data.

Definition at line 129 of file Array.cpp.

References te::common::GetPValue().
