Method Detail

createConstantObjectArray

public static ConstantObjectArray createConstantObjectArray()

createConstantHolesObjectArray

public static AbstractConstantArray createConstantHolesObjectArray()

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.

getElementInBounds

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

Specified by:

getElementInBounds in class AbstractConstantArray

getElementInBoundsDirect

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

hasHoles

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

Overrides:

hasHoles 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

nextElementIndex

public long nextElementIndex(com.oracle.truffle.api.object.DynamicObject object,
                             long index0)

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

                                 long index0)

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

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

deleteElementImpl

                                     long index,
                                     boolean strict)

Specified by:

deleteElementImpl in class ScriptArray

setLengthImpl

public ScriptArray setLengthImpl(com.oracle.truffle.api.object.DynamicObject object,
                                 long length,
                                 ScriptArray.ProfileHolder profile)

Specified by:

setLengthImpl in class ScriptArray

createWriteableInt

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

Specified by:

createWriteableInt in class AbstractConstantArray

createWriteableDouble

public AbstractObjectArray createWriteableDouble(com.oracle.truffle.api.object.DynamicObject object,
                                                 long index,
                                                 double value,
                                                 ScriptArray.ProfileHolder profile)

Specified by:

createWriteableDouble in class AbstractConstantArray

createWriteableJSObject

public AbstractObjectArray createWriteableJSObject(com.oracle.truffle.api.object.DynamicObject object,
                                                   long index,
                                                   JSDynamicObject value,

public boolean isHolesType()

This array type can have holes. Use isHoles() to check whether the array does have holes.

Overrides:

isHolesType in class ScriptArray

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

withIntegrityLevel

protected DynamicArray withIntegrityLevel(int newIntegrityLevel)

Specified by:

withIntegrityLevel in class DynamicArray

ownPropertyKeys

public List<Object> ownPropertyKeys(com.oracle.truffle.api.object.DynamicObject object)

Overrides:
