Method Detail

get

public Object get(int index,
                  Scriptable start)

Description copied from class: ScriptableObject

Returns the value of the indexed property or NOT_FOUND.

Specified by:

get in interface Scriptable

Overrides:

get in class ScriptableObject

Parameters:

index - the numeric index for the property

start - the object in which the lookup began

Returns:

the value of the property (may be null), or NOT_FOUND

See Also:

Scriptable.get(String,Scriptable)

has

public boolean has(int index,
                   Scriptable start)

Description copied from class: ScriptableObject

Returns true if the property index is defined.

Specified by:

has in interface Scriptable

Overrides:

has in class ScriptableObject

Parameters:

index - the numeric index for the property

start - the object in which the lookup began

Returns:

true if and only if the property was found in the object

See Also:

Scriptable.get(int, Scriptable), ScriptableObject.getProperty(Scriptable, int)

put

public void put(int index,
                Scriptable start,
                Object val)

Description copied from class: ScriptableObject

Sets the value of the indexed property, creating it if need be.

Specified by:

put in interface Scriptable

Overrides:

put in class ScriptableObject

Parameters:

index - the numeric index for the property

start - the object whose property is being set

val - value to set the property to

See Also:

Scriptable.has(int, Scriptable), Scriptable.get(int, Scriptable), ScriptableObject.putProperty(Scriptable, int, Object), Context.toObject(Object, Scriptable)

delete

public void delete(int index)

Description copied from class: ScriptableObject

Removes the indexed property from the object. If the property is not found, or it has the PERMANENT attribute, no action is taken.

Specified by:

delete in interface Scriptable

Overrides:

delete in class ScriptableObject

Parameters:

index - the numeric index for the property

See Also:

Scriptable.get(int, Scriptable), ScriptableObject.deleteProperty(Scriptable, int)

getIds

public Object[] getIds()

Description copied from class: ScriptableObject

Returns an array of ids for the properties of the object.

Any properties with the attribute DONTENUM are not listed.

Specified by:

getIds in interface Scriptable

Overrides:

getIds in class ScriptableObject

Returns:

an array of java.lang.Objects with an entry for every listed property. Properties accessed via an integer index will have a corresponding Integer entry in the returned array. Properties accessed by a String will have a String entry in the returned array.

getBytesPerElement

public abstract int getBytesPerElement()

Return the number of bytes represented by each element in the array. This can be useful when wishing to manipulate the byte array directly from Java.

execIdCall

public Object execIdCall(IdFunctionObject f,
                         Context cx,
                         Scriptable scope,
                         Scriptable thisObj,
                         Object[] args)

Description copied from class: IdScriptableObject

'thisObj' will be null if invoked as constructor, in which case instance of Scriptable should be returned.

Specified by:

execIdCall in interface IdFunctionCall

Overrides:

execIdCall in class IdScriptableObject

getArrayElement

public Object getArrayElement(int index)

Description copied from interface: ExternalArrayData

Return the element at the specified index. The result must be a type that is valid in JavaScript: Number, String, or Scriptable. This method will not be called unless "index" is in range.

Specified by:

setArrayElement

public void setArrayElement(int index,
                            Object value)

Description copied from interface: ExternalArrayData

Set the element at the specified index. This method will not be called unless "index" is in range. The method must check that "value" is a valid type, and convert it if necessary.

Specified by:

setArrayElement in interface ExternalArrayData
