public TableRow(java.lang.String table,
        java.util.List<java.lang.String> columns)

Constructor

Parameters:

table - The name of the database table containing this row.

columns - A list of column names. Each member of the List is a String. After construction, the list of columns is fixed; attempting to access a column not in the list will cause an IllegalArgumentException to be thrown.

public java.lang.String getTable()

Return the name of the table containing this row, or null if this row is not associated with a database table.

Returns:

The name of the table containing this row

setTable

public void setTable(java.lang.String table)

hasColumn

public boolean hasColumn(java.lang.String column)

Return true if this row contains a column with this name.

Parameters:

column - The column name (case-insensitive)

Returns:

True if this row contains a column with this name.

hasColumnChanged

public boolean hasColumnChanged(java.lang.String column)

Return true if this row contains this column and the value has been updated.

Parameters:

column - The column name (case-insensitive)

Returns:

True if this row contains a column with this name.

isColumnNull

public boolean isColumnNull(java.lang.String column)

Return true if the column is an SQL NULL.

Parameters:

column - The column name (case-insensitive)

True if the column is an SQL NULL

getIntColumn

public int getIntColumn(java.lang.String column)

Return the integer value of column. If the column's type is not an integer, or the column does not exist, an IllegalArgumentException is thrown.

Parameters:

column - The column name (case-insensitive)

Returns:

The integer value of the column, or -1 if the column is an SQL null.

getLongColumn

public long getLongColumn(java.lang.String column)

Return the long value of column. If the column's type is not an long, or the column does not exist, an IllegalArgumentException is thrown.
