Examples with CharFunction org.eclipse.collections.api.block.function.primitive.CharFunction used on opensource projects

Example 1 with CharFunction

use of org.eclipse.collections.api.block.function.primitive.CharFunction in project eclipse-collections by eclipse.

the class ImmutableBagTestCase method collectChar.

@Override
@Test
public void collectChar() {
    super.collectChar();
    ImmutableCharBag result = this.newBag().collectChar((CharFunction<String>) string -> string.charAt(0));
    Assert.assertEquals(this.numKeys(), result.sizeDistinct());
    for (int i = 1; i <= this.numKeys(); i++) {
        Assert.assertEquals(i, result.occurrencesOf((char) ('0' + i)));
    }
}

Example 2 with CharFunction

use of org.eclipse.collections.api.block.function.primitive.CharFunction in project eclipse-collections by eclipse.

the class MapIterableTestCase method collectCharWithTarget.

@Test
public void collectCharWithTarget() {
    CharHashBag target = new CharHashBag();
    MapIterable<String, String> map = this.newMapWithKeysValues("One", "A1", "Two", "B", "Three", "C#++");
    CharHashBag result = map.collectChar((CharFunction<String>) string -> string.charAt(0), target);
    Assert.assertSame("Target sent as parameter not returned", target, result);
    Assert.assertEquals(CharHashBag.newBagWith('A', 'B', 'C'), result.toBag());
}

Example 3 with CharFunction
