Method Detail

initialize

public void initialize(java.lang.String filename)
                throws java.io.IOException

Description copied from interface: MDBService

Prepare the given .mdb file for reading. This method must be called before MDBService.parseDatabase().

Specified by:

initialize in interface MDBService

Throws:

java.io.IOException - if a problem occurs when opening the file

parseDatabase

public java.util.Vector<java.util.Vector<java.lang.String[]>> parseDatabase()
                                                                     throws java.io.IOException

Description copied from interface: MDBService

Read all tables from a pre-initialized .mdb files. Each Vector in the outer Vector represents a table; each String[] in a table represents a row, and each element of the String[] represents the value of a particular column within the row. The first row in each table contains the names for each column. The first entry in the column name row is the name of the table. MDBService.initialize(String) must be called before calling parseDatabase().

Specified by:

parseDatabase in interface MDBService

Throws:

java.io.IOException - if there is a problem reading the table data

parseTable

public java.util.Vector<java.lang.String[]> parseTable(java.lang.String name)
                                                throws java.io.IOException

Description copied from interface: MDBService

Read named table from a pre-initialized .mdb files. Each String[] in a table represents a row, and each element of the String[] represents the value of a particular column within the row. The first row in the table contains the names for each column. MDBService.initialize(String) must be called before calling parseTable.

Specified by:

parseTable in interface MDBService

Parameters:

name - table name

Returns:

table data or null if the named table does not exist

Throws:

java.io.IOException - if there is a problem reading the table data

close

public void close()

Description copied from interface: MDBService

Close the currently initialized file.

Specified by:

close in interface MDBService

fetchRow

private boolean fetchRow(mdbtools.libmdb.MdbTableDef table)

Fetches the next row from the table, ignoring potential parsing exceptions.

Parameters:

table - Table to fetch the next available row from.

Returns:

true if there are further rows to fetch. false if there are no further rows to fetch or an exception is thrown while parsing the row.
