Example 76 with Iterator

use of java.util.Iterator in project groovy-core by groovy.

the class NumberRangeTest method testStepByOneWithClosure.

/**
     * Tests stepping through a range with a closure.
     */
public void testStepByOneWithClosure() {
    final List callLog = new ArrayList();
    final Closure closure = new RecordingClosure(callLog);
    final Range range = createRange(1, 5);
    range.step(1, closure);
    assertEquals("wrong number of calls to closure", 5, callLog.size());
    final Iterator iter = callLog.iterator();
    for (int i = 1; i <= 5; i++) {
        assertEquals("wrong argument passed to closure", createValue(i), iter.next());
    }
}

Example 77 with Iterator

use of java.util.Iterator in project groovy-core by groovy.

the class NumberRangeTest method testRemoveFromIterator.

/**
     * Tests removing an element from the range using an iterator (not supported).
     */
public void testRemoveFromIterator() {
    final Range range = createRange(1, 5);
    try {
        final Iterator iter = range.iterator();
        iter.remove();
        fail("successfully removed an element using an iterator");
    } catch (UnsupportedOperationException e) {
        assertTrue("expected exception thrown", true);
    }
}

Example 78 with Iterator

use of java.util.Iterator in project groovy-core by groovy.

the class NumberRangeTest method testStepByTwoWithClosure.

/**
     * Tests stepping through a range by two with a closure.
     */
public void testStepByTwoWithClosure() {
    final List callLog = new ArrayList();
    final Closure closure = new RecordingClosure(callLog);
    final Range range = createRange(0, 4);
    range.step(2, closure);
    assertEquals("wrong number of calls to closure", 3, callLog.size());
    final Iterator iter = callLog.iterator();
    for (int i = 0; i <= 4; i += 2) {
        assertEquals("wrong argument passed to closure", createValue(i), iter.next());
    }
}

Example 79 with Iterator

use of java.util.Iterator in project groovy-core by groovy.

the class NumberRangeTest method testNegativeReverseStepByOneWithClosure.

/**
     * Tests stepping backwards through a reversed range with a closure.
     */

    final List callLog = new ArrayList();
    final Closure closure = new RecordingClosure(callLog);
    final Range range = createRange(5, 1);
    range.step(-1, closure);
    assertEquals("wrong number of calls to closure", 5, callLog.size());
    final Iterator iter = callLog.iterator();
    for (int i = 1; i <= 5; i++) {
        assertEquals("wrong argument passed to closure", createValue(i), iter.next());
    }
}

Example 80 with Iterator

use of java.util.Iterator in project groovy-core by groovy.

the class NumberRangeTest method testStepByOne.

/**
     * Tests stepping through a range by one.
     */
public void testStepByOne() {
    final Range range = createRange(1, 5);
    final List result = range.step(1);
    assertEquals("wrong number of calls", 5, result.size());
