Method Details

getNumSubShapes

public int getNumSubShapes()

Count the sub-shapes.

Returns:

the count (≥0)

getSubShape

public SubShape getSubShape(int subShapeIndex)

Access the specified sub-shape.

Parameters:

subShapeIndex - the index of a subshape within the current compound shape (≥0)

Returns:

a new JVM object with the pre-existing native object assigned

getSubShapeIdFromIndex

public SubShapeIdCreator getSubShapeIdFromIndex(int subShapeIndex,
 SubShapeIdCreator parent)

Convert a sub-shape index to a sub-shape ID. (native method: GetSubShapeIDFromIndex)

Parameters:

subShapeIndex - the index of a subshape within the current compound shape (≥0)

parent - a path the the current compound shape (not null, unaffected)

Returns:

a new object

getSubShapes

public SubShape[] getSubShapes()

Access all the sub-shapes as an array.

Returns:

a new array of new JVM objects with pre-existing native objects assigned

restoreSubShapeState

public void restoreSubShapeState(ShapeList subshapes)

Restore the sub-shape references after invoking sRestoreFromBinaryState().

Parameters:

subshapes - the desired sub-shape references (not null)
