Detailed Description

reads and encapsulates a VPF table header

Member Typedef Documentation

typedef VPFUtil::PointerArray<ColumnDefinition> disti::VPFTableHeader::ColumnDefinitionArray

array of column definition pointers

Constructor & Destructor Documentation

VPFTableHeader::VPFTableHeader

(

VPFFile &

infile

)

Read the table header from the given VPF file. Infile will be "seeked" to just past the header on success.

Parameters

infile

VPF file to read header from (must be "seeked" to start of file)

Member Function Documentation

bool VPFTableHeader::FindColumn	(	const char *const	colName,
		unsigned int &	colIndex
	)		const

Find the column index to the column in the table header with the given column name

Parameters

colName	name of desired column
colIndex	[out] receives zero based column index on success

Returns

true if column found else false

unsigned int disti::VPFTableHeader::GetColumnCount ( void  ) const

inline

Get the number of columns in the table

Returns

number of columns in the table

const ColumnDefinition* disti::VPFTableHeader::GetColumnDefinition ( unsigned int  index ) const

inline

Get a column definition for a given column in the table

Parameters

index

zero based index into columns

Returns

column definition at index else NULL

const char* disti::VPFTableHeader::GetDescription ( void  ) const

inline

Get the description from the table header /return description from the table header

VPFUtil::EndianMode disti::VPFTableHeader::GetEndianMode ( void  ) const

inline

Get the endian mode read from the table header

Returns

the endian mode from the table header

const char* disti::VPFTableHeader::GetNarrativeFilename ( void  ) const

inline

Get the filename of a narrative file associated with the table header

Returns

narrative filename

bool disti::VPFTableHeader::IsValid ( void  ) const

inline

Returns

True if the header was read successfully from the file
