Methods

prepareTranslations()

protected prepareTranslations(ctx, renames): Translations

Defined in: core/dist/visitors/attribute-renamer.d.ts:38

Prepares variable map for renaming by reversing the translation map from the variable-mapper context.

Parameters

Parameter	Type
ctx	VariableMapperCtx
renames	RenameMap

Iterates array in place, replacing each ASTIdentifier element with its renamed version.

Parameters

Parameter	Type	Description
array	OpOrId[]	-
