Interface CharacterRange
- All Superinterfaces:
- ClassFileElement,- CodeElement,- PseudoInstruction
A pseudo-instruction which models a single entry in the 
 
CharacterRangeTable attribute.  Delivered as a
 CodeElement during traversal of the elements of a CodeModel,
 according to the setting of the ClassFile.DebugElementsOption option.
 A character range entry is composite:
CharacterRange(
    Label startScope,
    Label endScope,
    int characterRangeStart,
    int characterRangeEnd,
    int flags
)
 Another model, CharacterRangeInfo, also models a character range
 entry;  it has no dependency on a CodeModel and represents of bci
 values as ints instead of Labels, and is used as components
 of a CharacterRangeTableAttribute.

characterRangeStartint characterRangeStart()Returns the encoded start of the character range region (inclusive). The value is constructed from the line_number/column_number pair as given byline_number << 10 + column_number, where the source file is viewed as an array of (possibly multi-byte) characters.- Returns:
- the encoded start of the character range region (inclusive)
