Method Details

setElementImpl

public final ScriptArray setElementImpl(JSDynamicObject object,
 long index,
 Object value,
 boolean strict)

Specified by:

setElementImpl in class ScriptArray

getElement

public final Object getElement(JSDynamicObject object,
 long index)

Specified by:

getElement in class ScriptArray

getElementInBounds

public final Object getElementInBounds(JSDynamicObject object,
 long index)

Specified by:

getElementInBounds in class ScriptArray

getElementInBounds

public abstract Object getElementInBounds(JSDynamicObject object,
 int index)

firstElementIndex

public long firstElementIndex(JSDynamicObject object)

Description copied from class: ScriptArray

First element index (inclusive).

Specified by:

firstElementIndex in class ScriptArray

lastElementIndex

public long lastElementIndex(JSDynamicObject object)

Description copied from class: ScriptArray

Last element index (inclusive).

Specified by:

lastElementIndex in class ScriptArray

nextElementIndex

public long nextElementIndex(JSDynamicObject 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().

Specified by:

nextElementIndex in class ScriptArray

previousElementIndex

public long previousElementIndex(JSDynamicObject object,
 long index)

Description copied from class: ScriptArray

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

Specified by:

previousElementIndex in class ScriptArray

isInBoundsFast

public final boolean isInBoundsFast(JSDynamicObject object,
 long index)

Returns true if the index can be written using inBoundsFast access mode.

Overrides:

isInBoundsFast in class ScriptArray

createWriteableDouble

public abstract AbstractWritableArray createWriteableDouble(JSDynamicObject object,
 long index,
 double value,
 com.oracle.truffle.api.nodes.Node node,
 ScriptArray.CreateWritableProfileAccess profile)

createWriteableInt

public abstract AbstractWritableArray createWriteableInt(JSDynamicObject object,
 long index,
 int value,
 com.oracle.truffle.api.nodes.Node node,
 ScriptArray.CreateWritableProfileAccess profile)

createWriteableObject

public abstract AbstractWritableArray createWriteableObject(JSDynamicObject object,
 long index,
 Object value,
 com.oracle.truffle.api.nodes.Node node,
 ScriptArray.CreateWritableProfileAccess profile)

createWriteableJSObject

public abstract AbstractWritableArray createWriteableJSObject(JSDynamicObject object,
 long index,
 JSDynamicObject value,
 com.oracle.truffle.api.nodes.Node node,
 ScriptArray.CreateWritableProfileAccess profile)

hasHoles

public boolean hasHoles(JSDynamicObject object)

Description copied from class: ScriptArray

Returns true when this array actually has holes between ScriptArray.firstElementIndex(JSDynamicObject) and ScriptArray.lastElementIndex(JSDynamicObject). Implies ScriptArray.isHolesType().

Specified by:

hasHoles in class ScriptArray
