public ColumnsMeta()

Constructs a new ColumnsMeta object with no columns.

ColumnsMeta

public ColumnsMeta(java.lang.String[] pColsName,
                   int[] pJdbcTypes,
                   boolean[] pNullables,
                   java.lang.String[] pDescriptions,
                   java.lang.String[] pPKColumns)

Constructs a new ColumnsMeta object with a set of columns. The set of columns is created from several arrays containing the main column properties, in the same order as the columns: The first column's name should be first in the array of column names, and its type first in the array of JDBC types, and so on.

Parameters:

pColsName - array of column names

pJdbcTypes - array of JDBC types

pNullables - array of Booleans indicating if the columns are nullable

pDescriptions - array of column descriptions. These descriptions are used to generate the WDSL

pPKColumns - array of column names that are part of the primary key

Method Detail

addColumnMeta

public void addColumnMeta(java.lang.String pColumnName,
