Overrides:

nextElementIndex

public long nextElementIndex(com.oracle.truffle.api.object.DynamicObject object,
                             long index0)

Description copied from class: ScriptArray

Returns the next index. The index is guaranteed either to exist, or be MAX_SAFE_INTEGER. Reason for MAX_SAFE_INTEGER is: this array could be the prototype of another one; returning the length() of this array would be wrong, if the inheriting array is longer, but has a hole at length().

Overrides:

nextElementIndex in class AbstractWritableArray

previousElementIndex

public long previousElementIndex(com.oracle.truffle.api.object.DynamicObject object,
                                 long index0)

Description copied from class: ScriptArray

Returns the previous index. The index is guaranteed either to exist, or be smaller than firstElementIndex().

Overrides:

previousElementIndex in class AbstractWritableArray

hasElement

public boolean hasElement(com.oracle.truffle.api.object.DynamicObject object,
                          long index)

Overrides:

Returns:

true if array has an element (not a hole) at this index.

deleteElementImpl

public ScriptArray deleteElementImpl(com.oracle.truffle.api.object.DynamicObject object,

Overrides:

deleteElementImpl in class AbstractObjectArray

isHolesType

public boolean isHolesType()

Description copied from class: ScriptArray

Returns true when the this array could have hole values in it. Doesn't tell whether it actually HAS holes.

Overrides:

isHolesType in class ScriptArray

removeRangeImpl

public ScriptArray removeRangeImpl(com.oracle.truffle.api.object.DynamicObject object,
                                   long start,
                                   long end)

Description copied from class: ScriptArray

This function deletes all elements in the range from [start..end[. This is equivalent to shifting the whole array, starting with element index end, by end-start positions to the left. Can be used by e.g. Array.prototype.splice;

Specified by:

removeRangeImpl in class ScriptArray

castNonNull

protected Object castNonNull(Object value)

Overrides:

castNonNull in class AbstractObjectArray

withIntegrityLevel

protected HolesObjectArray withIntegrityLevel(int newIntegrityLevel)

Specified by:

withIntegrityLevel in class AbstractObjectArray

ownPropertyKeys

public List<Object> ownPropertyKeys(com.oracle.truffle.api.object.DynamicObject object)

Overrides:

ownPropertyKeys in class ScriptArray
