public void setInBoundsFast(JSDynamicObject object,
 int index,
 int value)

Specified by:

setInBoundsFast in class AbstractIntArray

setLengthLess

protected final void setLengthLess(JSDynamicObject object,
 long length,
 com.oracle.truffle.api.nodes.Node node,
 ScriptArray.SetLengthProfileAccess profile)

Specified by:

setLengthLess in class AbstractWritableArray

prepareInBoundsFast

protected final int prepareInBoundsFast(JSDynamicObject object,
 long index)

Specified by:

prepareInBoundsFast in class AbstractWritableArray

setArrayOffset

protected final void setArrayOffset(JSDynamicObject object,
 int arrayOffset)

Overrides:

setArrayOffset in class AbstractWritableArray

getArrayOffset

protected final int getArrayOffset(JSDynamicObject object)

Description copied from class: AbstractWritableArray

The arrayOffset (int) is the first element in internal array.

Overrides:

getArrayOffset in class AbstractWritableArray

setIndexOffset

protected final void setIndexOffset(JSDynamicObject object,
 long indexOffset)

Overrides:

setIndexOffset in class AbstractWritableArray

getIndexOffset

protected final long getIndexOffset(JSDynamicObject object)

Description copied from class: AbstractWritableArray

The indexOffset (int) is the first element is in array[indexOffset + arrayOffset].

Overrides:

getIndexOffset in class AbstractWritableArray

firstElementIndex

public final long firstElementIndex(JSDynamicObject object)

Description copied from class: ScriptArray

First element index (inclusive).

Specified by:

firstElementIndex in class ScriptArray

lastElementIndex

public final long lastElementIndex(JSDynamicObject object)

Description copied from class: ScriptArray

Last element index (inclusive).

Specified by:

lastElementIndex in class ScriptArray

addRangeImpl

public ScriptArray addRangeImpl(JSDynamicObject 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

Parameters:

offset - starting offset position

size - size of the inserted empty array

Returns:

a ScriptArray instance with the new size
