Method Detail

addTextEdit

protected void addTextEdit(Expression expression,
                           int extraOffset,
                           java.lang.String oldValue,
                           java.lang.String newValue)

Adds a new TextEdit with the given information.

Parameters:

expression - The Expression which should be refactored, it will be used to retrieve the offset of the change

extraOffset - Additional offset that will be added to the given Expression's offset, which is the length of the string representation of what is before it

oldValue - The old value to change to the new one

newValue - The new value

addTextEdit

protected void addTextEdit(Expression expression,
                           java.lang.String oldValue,
                           java.lang.String newValue)

Adds a new TextEdit with the given information.

Parameters:

expression - The Expression which should be refactored, it will be used to retrieve the offset of the change

oldValue - The old value to change to the new one

newValue - The new value

buildTextEdit

protected TextEdit buildTextEdit(int offset,
                                 java.lang.String oldValue,
                                 java.lang.String newValue)

Creates a new TextEdit for the given refactoring information.

Parameters:

offset - The position where the change should be made within the actual JPQL fragment

oldValue - The old value to change to the new one

newValue - The new value

Returns:

A new TextEdit

reposition

protected int reposition(int offset)

Repositions the given position that is based on the generated JPQL query to be the position from the JPQL fragment that was parsed.

Parameters:

offset - The position within the string generated by Expression.toActualText()

Returns:

The position within the JPQL fragment that was passed to the refactoring tool
