Constructor Detail

AbstractConstantEmptyArray

protected AbstractConstantEmptyArray(int integrityLevel,
                                     DynamicArray.DynamicArrayCache cache)

Method Detail

setCapacity

protected static void setCapacity(com.oracle.truffle.api.object.DynamicObject object,
                                  long length)

getCapacity

protected static long getCapacity(com.oracle.truffle.api.object.DynamicObject object)

getElementInBounds

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

Specified by:

getElementInBounds in class AbstractConstantArray

lengthInt

public int lengthInt(com.oracle.truffle.api.object.DynamicObject object)

Specified by:

lengthInt in class ScriptArray

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.

Specified by:

toArray in class ScriptArray

cloneArray

public Object cloneArray(com.oracle.truffle.api.object.DynamicObject object)

Specified by:

cloneArray in class DynamicArray

hasElement

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

Specified by:

hasElement in class ScriptArray

Returns:

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

deleteElementImpl

public ScriptArray deleteElementImpl(com.oracle.truffle.api.object.DynamicObject object,
                                     long index,
                                     boolean strict)

Specified by:

deleteElementImpl in class ScriptArray

firstElementIndex

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

Description copied from class: ScriptArray

First element index (inclusive).

Overrides:

firstElementIndex in class AbstractConstantArray

lastElementIndex

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

Description copied from class: ScriptArray

Last element index (inclusive).

Overrides:

lastElementIndex in class AbstractConstantArray

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 AbstractConstantArray

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().

Overrides:

previousElementIndex in class AbstractConstantArray

createWriteableInt

public AbstractIntArray createWriteableInt(com.oracle.truffle.api.object.DynamicObject object,
                                           long index,
                                           int value,
                                           ScriptArray.ProfileHolder profile)
