Detailed Description

< VPF table column definition

Constructor & Destructor Documentation

ColumnDefinition

(

VPFFile &

infile

)

Construct a VPF table column definition read from the given file. Input file should be "seeked" to beginning of column definition and will end "seeked" one past end of column separator

Parameters

infile

input file to read description from

~ColumnDefinition

(

)

Member Function Documentation

bool CheckDefinition	(	const Check &	colCheck,
		const bool	colCanBeNULL = false
	)		const

Determine if this column definition matches the given column check

Parameters

colCheck	column check
colCanBeNULL	[optional, defaults to false] true if column can optionally be a NULL data type and pass this check test

Returns

true if matches else false

VPFUtil::DataType GetDataType ( void  ) const

inline

Get the data type of the column

Returns

data type of the column

const char* GetDescription ( void  ) const

inline

Get description of column

Returns

description of column else NULL if not valid

VPFUtil::KeyType GetKeyType ( void  ) const

inline

Get the key type for the column

Returns

key type for the column

const char* GetName ( void  ) const

inline

Get the name of the column

Returns

name of the column else "" if not valid

const char* GetNarrativeTableName ( void  ) const

inline

Get the narrative table name of the column

Returns

narrative table name of the column else "" if not valid

int GetNumberOfElements ( void  ) const

inline

Get the number of data elements in the column

Returns

number of data elements in the column (-1 indicates variable length)

const char* GetThematicIndexName ( void  ) const

inline

Get the thematic indexes name of the column

Returns

thematic indexes name of the column else "" if not valid

const char* GetValueDescriptionTableName ( void  ) const

inline

Get the value description table name of the column

Returns

value description table name of the column else "" if not valid

bool IsValid ( void  ) const

inline

Determine if a valid column definition was read

Returns

true if valid else false

bool ReadNumElements ( VPFFile &  infile )

protected

Read the number of elements and populate _numElements accordingly. _numElements gets -1 if variable length is indicated. Input file should be "seeked" to num elements field and will end "seeked" one past column def delimiter

Parameters

infile

input file to read number of elements

Returns

true on success else false
