Method Detail

setElementImpl

public final ScriptArray setElementImpl(com.oracle.truffle.api.object.DynamicObject object,
                                        long index,
                                        Object value,
                                        boolean strict)

Specified by:

setElementImpl in class ScriptArray

getElement

public final Object getElement(com.oracle.truffle.api.object.DynamicObject object,
                               long index)

Specified by:

getElement in class ScriptArray

getElementInBounds

public final Object getElementInBounds(com.oracle.truffle.api.object.DynamicObject object,
                                       long index)

Specified by:

getElementInBounds in class ScriptArray

getElementInBounds

public abstract Object getElementInBounds(com.oracle.truffle.api.object.DynamicObject object,
                                          int index)

length

public final long length(com.oracle.truffle.api.object.DynamicObject object)

Specified by:

length in class ScriptArray

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

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().

Specified by:

nextElementIndex in class ScriptArray

previousElementIndex

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

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

Overrides:
