Field Detail

EMPTY

private static final ImmutableMapValueImpl EMPTY

kvs

private final Value[] kvs

Constructor Detail

ImmutableMapValueImpl

public ImmutableMapValueImpl(Value[] kvs)

Method Detail

empty

public static ImmutableMapValue empty()

getValueType

public ValueType getValueType()

Description copied from interface: Value

Returns type of this value. Note that you can't use instanceof to check type of a value because type of a mutable value is variable.

Specified by:

getValueType in interface Value

immutableValue

public ImmutableMapValue immutableValue()

Description copied from interface: Value

Returns immutable copy of this value. This method simply returns this without copying the value if this value is already immutable.

Specified by:

immutableValue in interface Value

asMapValue

public ImmutableMapValue asMapValue()

Description copied from interface: Value

Returns the value as MapValue. Otherwise throws MessageTypeCastException. Note that you can't use instanceof or cast ((MapValue) thisValue) to check type of a value because type of a mutable value is variable.

Specified by:

asMapValue in interface ImmutableValue

Specified by:

asMapValue in interface Value

Overrides:

asMapValue in class AbstractImmutableValue

getKeyValueArray

public Value[] getKeyValueArray()

Description copied from interface: MapValue

Returns the key-value pairs as an array of Value. Odd elements are keys. Next element of an odd element is a value corresponding to the key. For example, if this value represents {"k1": "v1", "k2": "v2"}, this method returns ["k1", "v1", "k2", "v2"].

Specified by:

getKeyValueArray in interface MapValue

size

public int size()

Description copied from interface: MapValue

Returns number of key-value pairs in this array.

Specified by:

size in interface MapValue

keySet

public java.util.Set<Value> keySet()

Specified by:

keySet in interface MapValue

entrySet

public java.util.Set<java.util.Map.Entry<Value,Value>> entrySet()

Specified by:

entrySet in interface MapValue

values

public java.util.Collection<Value> values()

Specified by:

values in interface MapValue

map

public java.util.Map<Value,Value> map()

Description copied from interface: MapValue

Returns the value as Map.

Specified by:

map in interface MapValue

writeTo

public void writeTo(MessagePacker pk)
             throws java.io.IOException

Description copied from interface: Value

Serializes the value using the specified MessagePacker

Specified by:

writeTo in interface Value

Throws:

java.io.IOException

See Also:

MessagePacker

equals

public boolean equals(java.lang.Object o)

Description copied from interface: Value

Compares this value to the specified object. This method returns true if type and value are equivalent. If this value is MapValue or ArrayValue, this method check equivalence of elements recursively.

Specified by:

equals in interface Value

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toJson

public java.lang.String toJson()

Description copied from interface: Value

Returns json representation of this Value.

Following behavior is not configurable at this release and they might be changed at future releases:

• if a key of MapValue is not string, the key is converted to a string using toString method.
• NaN and Infinity of DoubleValue are converted to null.
• ExtensionValue is converted to a 2-element array where first element is a number and second element is the data encoded in hex.
• BinaryValue is converted to a string using UTF-8 encoding. Invalid byte sequence is replaced with U+FFFD replacement character.
• Invalid UTF-8 byte sequences in StringValue is replaced with U+FFFD replacement character

Specified by:

toJson in interface Value

appendJsonKey

private static void appendJsonKey(java.lang.StringBuilder sb,
                                  Value key)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

appendString

private static void appendString(java.lang.StringBuilder sb,
                                 Value value)
