Example 16 with PropertyAccessor

use of org.springframework.expression.PropertyAccessor in project spring-framework by spring-projects.

the class PropertyAccessTests method addingAndRemovingAccessors.

@Test
void addingAndRemovingAccessors() {
    StandardEvaluationContext ctx = new StandardEvaluationContext();
    // reflective property accessor is the only one by default
    assertThat(ctx.getPropertyAccessors()).hasSize(1);
    StringyPropertyAccessor spa = new StringyPropertyAccessor();
    ctx.addPropertyAccessor(spa);
    assertThat(ctx.getPropertyAccessors()).hasSize(2);
    List<PropertyAccessor> copy = new ArrayList<>(ctx.getPropertyAccessors());
    assertThat(ctx.removePropertyAccessor(spa)).isTrue();
    assertThat(ctx.removePropertyAccessor(spa)).isFalse();
    assertThat(ctx.getPropertyAccessors()).hasSize(1);
    ctx.setPropertyAccessors(copy);
    assertThat(ctx.getPropertyAccessors()).hasSize(2);
}

Example 17 with PropertyAccessor
