                                  long index,

Specified by:

toArray

public Object[] toArray(com.oracle.truffle.api.object.DynamicObject object)

Description copied from class: ScriptArray

Creates an Object[] from this array, of size array.length. Does not check the prototype chain, i.e. result can be wrong. Use JSToObjectArrayNode for more correct results.

Overrides:

toArray in class AbstractWritableArray

firstElementIndex

public long firstElementIndex(com.oracle.truffle.api.object.DynamicObject object)

Description copied from class: ScriptArray

First element index (inclusive).

Specified by:

firstElementIndex in class ScriptArray

lastElementIndex

public long lastElementIndex(com.oracle.truffle.api.object.DynamicObject object)

Description copied from class: ScriptArray

Last element index (inclusive).

Specified by:

lastElementIndex 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

addRangeImpl

public ScriptArray addRangeImpl(com.oracle.truffle.api.object.DynamicObject object,
                                long offset,
                                int size)

Description copied from class: ScriptArray

This method grows the array by adding more elements of a given size. An offset parameter can be used to specify where the new elements have to be added (starting from zero). The operation is equivalent to shifting (right) the whole array or its part as defined by the offset parameter.

Specified by:

addRangeImpl in class ScriptArray

offset - starting offset position

size - size of the inserted empty array

Returns:

a ScriptArray instance with the new size

hasHoles

public boolean hasHoles(com.oracle.truffle.api.object.DynamicObject object)

Specified by:

hasHoles in class ScriptArray

withIntegrityLevel

protected ZeroBasedJSObjectArray withIntegrityLevel(int newIntegrityLevel)

Specified by:

withIntegrityLevel in class AbstractJSObjectArray

nextElementIndex

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

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
