Constructor Detail

TableHeader

public TableHeader(int length,
                   char byteOrder,
                   String description,
                   String narrativeTable,
                   List<TableColumnDef> columnDefs)

Creates a new TableHeader instance.

Parameters:

length - an int value of table header length.

byteOrder - a char value byte order used in table file.

description - a String value text description of found in header of this table.

narrativeTable - a String value file name of narrative table.

columnDefs - a List value of all column definitions for this table.

Method Detail

toString

public String toString()

Method toString returns content of all fields values. Used only for test and debug purpose.

Overrides:

toString in class Object

Returns:

a String value

getLength

public int getLength()

Method getRecordSize is used to return size in bytes of records stored in this table. If table keeps variable length records -1 should be returned.

Specified by:

getRecordSize in interface VPFHeader

Returns:

an int value

getByteOrder

public char getByteOrder()

getDescription

public String getDescription()

Gets the value of the description of table content.

Returns:

the value of description

getNarrativeTable

public String getNarrativeTable()

Gets the value of narrativeTable variable file name.

Returns:

the value of narrativeTable

getColumnDefs

public List<TableColumnDef> getColumnDefs()

Gets the value of columnDefs variable keeping definitions of all columns in this table.

Returns:

the value of columnDefs
