Method Details

getDataSize

public int getDataSize()
Gets the number of bytes of data that should have been transferred. This number may be approximate if data conversions were being performed. The value may be -1 if the size is unknown.
Returns:
the number of bytes of data that should have been transferred

getIndex

public int getIndex()
Retrieves the index of the column or parameter that was truncated.

This may be -1 if the column or parameter index is unknown, in which case the parameter and read fields should be ignored.

Returns:
the index of the truncated paramter or column value

getParameter

public boolean getParameter()
Indicates whether the value truncated was a parameter value or a column value.
Returns:
true if the value truncated was a parameter; false if it was a column value

getRead

public boolean getRead()
Indicates whether or not the value was truncated on a read.
Returns:
true if the value was truncated when read from the database; false if the data was truncated on a write

getTransferSize

public int getTransferSize()
Gets the number of bytes of data actually transferred. The value may be -1 if the size is unknown.
Returns:
the number of bytes of data actually transferred
