Method Detail

bindBlob

public void bindBlob(java.sql.PreparedStatement statement,
                     byte[] data,
                     int idx)
              throws java.sql.SQLException

Parameters:

statement -

data -

idx -

Throws:

java.sql.SQLException

convertTypes

public void convertTypes(java.lang.Object[] data,
                         AttributeTypeColumn[] cols)

If we have an Array of a scalar datatype, we may store that in the database as a long string. This method will convert the long string into an array of the scalar data types. This method will convert the data from the database into the correct format for the Object.

Parameters:

data -

cols -

convertType

public java.lang.Object convertType(AttributeTypeColumn col,
                                    java.lang.Object obj)

Convert the data represented by 'obj' to the correct data type as specified by 'col'.

Parameters:

col - AttributeTypeColumn from a class description.

obj -

Returns:

An instance of the expected type.

needsArrayConversion

public boolean needsArrayConversion(AttributeTypeColumn col)

Check to see the the field represented by this AttributeTypeColumn is a native array.

Parameters:

col -

Returns:

convertArrays

public boolean convertArrays(java.lang.Object[] map,
                             AttributeTypeColumn[] cols)

If we have an Array of a scalar datatype, we may store that in the database as a long string. This method will convert the array into a long string. I've used '\n' the new line character to sperate entries. This could cause problems but many of the other characters were having troubles getting in an out of the datatbase.

Parameters:

map -

cols -

Returns:
