All Implemented Interfaces:

Externalizable, Serializable

public class WTStringMap

extends Object

implements Externalizable

WTStringMap class maps keys to values. Both the keys and the values must be of type String. A map contains no duplicate keys; each key can map to at most one value.

setMapString

protected void setMapString(String a_MapString)
                     throws WTPropertyVetoException

Sets the value of the attribute: mapString; Internal representation of the map. If not null (empty map) it is composed of a comma separated list of keys and values.

toString

public String toString()

Returns the internal string representation of the object. Can be null.

Supported API: false

Returns:

clear

public void clear()

Removes all mappings from this map.

Supported API: false

containsKey

public boolean containsKey(String key)

Returns true if this map contains a mapping for the specified key.

Supported API: false

Parameters:

key -

Returns:

boolean

containsValue

public boolean containsValue(String value)

Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)).

Supported API: false

Parameters:

boolean

equals

public boolean equals(Object obj)

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two WTStringMaps represent the same mappings. More formally, two maps t1 and t2 represent the same mappings if t1.entrySet().equals(t2.entrySet()).

Supported API: false

Parameters:

Returns:

boolean

get

public String get(String key)

Returns the value to which this map maps the specified key. Returns null if the map contains no mapping for this key. A return value of null does indicates that the map contains no mapping for the key.

isEmpty

public boolean isEmpty()

Returns true if this map contains no key-value mappings.

Supported API: false

Returns:

boolean
