Class SourceRange

  • All Implemented Interfaces:
    ISourceRange
    public final class SourceRange
extends java.lang.Object
implements ISourceRange
    A source range defines an element's source coordinates relative to its source buffer.

        public SourceRange​(int offset,
                   int length)

      • isAvailable

        public static boolean isAvailable​(ISourceRange range)
        Helper method that answers whether a valid source range is available in the given ISourceRange. When an element has no associated source code, Java Model APIs may return either null or a range of [-1, 0] to indicate an invalid range. This utility method can be used to detect that case.
        Parameters:
        range - a source range, can be null
        Returns:
        true iff range is not null and range.getOffset() is not -1

      • equals

        public boolean equals​(java.lang.Object obj)
        Overrides:
        equals in class java.lang.Object

      • getLength

        public int getLength()
        Description copied from interface: ISourceRange
        Returns the number of characters of the source code for this element, relative to the source buffer in which this element is contained.
        Specified by:
        getLength in interface ISourceRange
        Returns:
        the number of characters of the source code for this element, relative to the source buffer in which this element is contained
        See Also:
        ISourceRange

      • getOffset

        public int getOffset()
        Description copied from interface: ISourceRange
        Returns the 0-based index of the first character of the source code for this element, relative to the source buffer in which this element is contained. However, if the element has no associated source code, an implementation may return -1.
        Specified by:
        getOffset in interface ISourceRange
        Returns:
        the 0-based index of the first character of the source code for this element, relative to the source buffer in which this element is contained. However, if the element has no associated source code, an implementation may return -1.
