Method Details

equals

public boolean equals(Object otherItem)

Description copied from interface: Item

Tests for logical equality. The semantics are that of the eq operator.

Specified by:

equals in interface Item

Overrides:

equals in class Object

Parameters:

otherItem - another item.

Returns:

true it is equal to other, false otherwise.

getKeys

public List<String> getKeys()

Description copied from interface: Item

Returns the keys of the item, if it is an object.

Specified by:

getKeys in interface Item

Returns:

the list of the keys.

getValues

public List<Item> getValues()

Description copied from interface: Item

Returns the values of the item, if it is an object.

Specified by:

getValues in interface Item

Returns:

the list of the value items.

getItemByKey

public Item getItemByKey(String s)

Description copied from interface: Item

Returns the value associated with a specific key, if it is an object.

Specified by:

getItemByKey in interface Item

Parameters:

s - a key.

Returns:

the value associated with key.

putItemByKey

public void putItemByKey(String s,
 Item value)

Description copied from interface: Item

Adds a key-value pair, if it is an object item.

Specified by:

putItemByKey in interface Item

Parameters:

s - a key.

value - a value.

putLazyItemByKey

public void putLazyItemByKey(String s,
 RuntimeIterator iterator,
 DynamicContext context,
 boolean isArray)

Description copied from interface: Item

Adds a key-value pair, if it is an object item. The value is lazily computed.

Specified by:

putLazyItemByKey in interface Item

Parameters:

s - a key.

iterator - a runtime iterator.

context - a dynamic context.

isArray - whether to always wrap the result in an array.

isObject

public boolean isObject()

Description copied from interface: Item

Tests whether the item is an object.

Specified by:

isObject in interface Item

Returns:

true if it is an object, false otherwise.

write

public void write(com.esotericsoftware.kryo.Kryo kryo,
 com.esotericsoftware.kryo.io.Output output)

Specified by:

write in interface com.esotericsoftware.kryo.KryoSerializable

read

public void read(com.esotericsoftware.kryo.Kryo kryo,
 com.esotericsoftware.kryo.io.Input input)

Specified by:

read in interface com.esotericsoftware.kryo.KryoSerializable

hashCode

public int hashCode()

Description copied from interface: Item

Computes a hash code.

Specified by:

hashCode in interface Item

Overrides:

hashCode in class Object

Returns:

a hash code as an int.

getDynamicType

public ItemType getDynamicType()

Description copied from interface: Item

Returns the dynamic type of the item (only for error message purposes).

Specified by:

getDynamicType in interface Item

the dynamic type as an item type.

getEffectiveBooleanValue

public boolean getEffectiveBooleanValue()

Description copied from interface: Item

Returns the effective boolean value of the item, if atomic.

Specified by:

getEffectiveBooleanValue in interface Item

Returns:

the effective boolean value.
