Method Detail

rewriteFix

public static Fix rewriteFix(HintContext ctx,
             String displayName,
             TreePath what,
             String to)

Prepare a fix that will replace the given tree node (what) with the given code. Any variables in the to pattern will be replaced with their values from HintContext.getVariables(), HintContext.getMultiVariables() and HintContext.getVariableNames().

Parameters:

ctx - basic context for which the fix should be created

displayName - the display name of the fix

what - the tree node that should be replaced

to - the new code that should replaced the what tree node

Returns:

an editor fix that performs the required transformation

removeFromParent

public static Fix removeFromParent(HintContext ctx,
                   String displayName,
                   TreePath what)

Creates a fix that removes the given code corresponding to the given tree node from the source code.

Parameters:

ctx - basic context for which the fix should be created

displayName - the display name of the fix

what - the tree node that should be removed

Returns:

an editor fix that removes the give tree from the source code

requiresParenthesis

public static boolean requiresParenthesis(Tree inner,
                          Tree original,
                          Tree outter)

Checks whether putting inner tree into outter tree, when original is being replaced with inner requires parentheses.

Parameters:

inner - the new tree node that will be placed under outter

original - the tree node that is being replaced with inner

outter - the future parent node of inner

Returns:

true if and only if inner needs to be wrapped using TreeMaker.Parenthesized(com.sun.source.tree.ExpressionTree) to keep the original meaning.
