Package edu.uiuc.ncsa.security.storage.sql.internals

Class ColumnMap

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<String,Object>

edu.uiuc.ncsa.security.storage.sql.internals.ColumnMap

All Implemented Interfaces:

ConversionMap<String,Object>, Serializable, Cloneable, Map<String,Object>

Direct Known Subclasses:

XMLMap

public class ColumnMap
extends HashMap<String,Object>
implements ConversionMap<String,Object>

Helper class with a bunch of built in casts. It contains key value pairs, where the keys are SQL column names and the values are values. This practically contains the information for a single row in a database.

Note that the keys are all column names AND that the keys are automatically converted to/from lower case. This is because this object may have its values given from a result set metadata object and most vendors allow only case-insensitive column names, so they may or may not elect to convert them to lower or upper case as they see fit.

Method Detail

put

public Object put(String key,
                  Object value)

Specified by:

put in interface Map<String,Object>

Overrides:

put in class HashMap<String,Object>

get

public Object get(Object key)

Specified by:

get in interface Map<String,Object>

Overrides:

get in class HashMap<String,Object>

getString

public String getString(String key)

Description copied from interface: ConversionMap

Convenience method to change the value to a string

Specified by:

getString in interface ConversionMap<String,Object>

Returns:

getLong

public long getLong(String key)

Returns zero if the value is null;

Specified by:

getLong in interface ConversionMap<String,Object>

Parameters:

key -

Returns:

getInteger

public int getInteger(String key)

Returns zero if the value is null;

Specified by:

getInteger in interface ConversionMap<String,Object>

Parameters:

key -

Returns:

getBoolean

public boolean getBoolean(String key)

Description copied from interface: ConversionMap

Convenience method to change the value to a boolean

Specified by:

getBoolean in interface ConversionMap<String,Object>

Returns:

getDate

public Date getDate(String key)

Description copied from interface: ConversionMap
