Examples with TypeLiteral org.eclipse.jdt.core.dom.TypeLiteral used on opensource projects

Example 1 with TypeLiteral

use of org.eclipse.jdt.core.dom.TypeLiteral in project AutoRefactor by JnRouvignac.

the class EnumMapRatherThanHashMapRefactoring method resolveParameter.

/**
 * Map parameter for HashMap constructor to EnumMap constructor. HashMap(Map) ->
 * EnumMap(EnumMap) <br/>
 * other HashMap constructors -> EnumMap(Class) <br>
 *
 * @return correct parameter for EnumMap constructor

}

Example 2 with TypeLiteral

use of org.eclipse.jdt.core.dom.TypeLiteral in project AutoRefactor by JnRouvignac.

the class EnumSetRatherThanHashSetRefactoring method replace.
