Class AbstractTextRange

java.lang.Object
  org.eclipse.jpt.common.core.utility.AbstractTextRange

All Implemented Interfaces:

TextRange

Direct Known Subclasses:

TextRange.Empty

public abstract class AbstractTextRange
extends Object
implements TextRange

Partial implementation of text range. Provisional API: This class is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Since:

2.0

Method Summary

TextRange	buildTextRange(int offset, int length, int lineNumber) Build and return a new text range for the specified values if they differ from the text range.
boolean	equals(Object o) Return whether the offsets, lengths, and line numbers are the same.
