MapFieldValue

public MapFieldValue(MapDataType type)

MapFieldValue

public MapFieldValue(MapDataType type,
                     int initialCapacity)

Method Detail

getDataType

public MapDataType getDataType()

Overrides:

getDataType in class CompositeFieldValue

assign

public void assign(Object o)

Description copied from class: FieldValue

Assign this non-fieldvalue value to this field value. This is used to be able to assign ints to Integer field values and List to Array field values and such.

Override to accept the specific types that should be legal.

Specified by:

assign in class FieldValue

clone

public MapFieldValue clone()

Overrides:

clone in class FieldValue

equals

public boolean equals(Object o)

Checks if another object is equal to this set.

Specified by:

equals in interface Map<K extends FieldValue,V extends FieldValue>

Overrides:

equals in class CompositeFieldValue

Parameters:

o - the object to check for equality with

Returns:

true if o is an instance of WeightedSet and the two encapsulated Maps are equal, false otherwise

clear

public void clear()

Specified by:

clear in interface Map<K extends FieldValue,V extends FieldValue>

Specified by:

clear in class FieldValue

deserialize

public void deserialize(Field field,
                        FieldReader reader)

Description copied from class: FieldValue

Read a field value from the specified reader

Specified by:

deserialize in class FieldValue

printXml

public void printXml(XmlStream xml)

Specified by:

printXml in class FieldValue

serialize

public void serialize(Field field,
                      FieldWriter writer)

Description copied from class: FieldValue

Write out field value to the specified writer

Specified by:

serialize in class FieldValue

getWrappedValue

public Object getWrappedValue()

Description copied from class: FieldValue

Used to retrieve wrapped type for simple types, such that you can use get methods to retrieve ints and floats directly instead of Int/Float field values. Complex types that can't be specified by simple java types just return themself.

Overrides:

getWrappedValue in class FieldValue

containsKey

public boolean containsKey(Object key)

Specified by:

containsKey in interface Map<K extends FieldValue,V extends FieldValue>

containsValue

public boolean containsValue(Object value)

Specified by:

containsValue in interface Map<K extends FieldValue,V extends FieldValue>

entrySet

public Set<Map.Entry<K,V>> entrySet()

Specified by:

entrySet in interface Map<K extends FieldValue,V extends FieldValue>

get

public V get(Object key)

Specified by:

get in interface Map<K extends FieldValue,V extends FieldValue>

keySet

public Set<K> keySet()

Specified by:

keySet in interface Map<K extends FieldValue,V extends FieldValue>

put

public V put(K key,
             V value)

Specified by:

put in interface Map<K extends FieldValue,V extends FieldValue>

putAll

public void putAll(Map<? extends K,? extends V> m)

Specified by:

putAll in interface Map<K extends FieldValue,V extends FieldValue>

remove

public V remove(Object key)

Specified by:

remove in interface Map<K extends FieldValue,V extends FieldValue>

values

public Collection<V> values()

Specified by:

values in interface Map<K extends FieldValue,V extends FieldValue>

contains

public boolean contains(Object o)

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<K extends FieldValue,V extends FieldValue>

size

public int size()

Specified by:

size in interface Map<K extends FieldValue,V extends FieldValue>

compareTo

public int compareTo(FieldValue fieldValue)

Specified by:

compareTo in interface Comparable<K extends FieldValue>

Overrides:

compareTo in class FieldValue
