Examples with Expression org.apache.camel.Expression used on opensource projects

Example 1 with Expression

use of org.apache.camel.Expression in project camel by apache.

the class CamelTestSupport method assertExpression.

/**
     * Asserts that the given language name and expression evaluates to the
     * given value on a specific exchange
     */
protected void assertExpression(Exchange exchange, String languageName, String expressionText, Object expectedValue) {
    Language language = assertResolveLanguage(languageName);
    Expression expression = language.createExpression(expressionText);
    assertNotNull(expression, "No Expression could be created for text: " + expressionText + " language: " + language);
    assertExpression(expression, exchange, expectedValue);
}

Example 2 with Expression

use of org.apache.camel.Expression in project camel by apache.

the class LanguageTestSupport method assertExpression.

/**
     * Asserts that the expression evaluates to one of the two given values
     */
protected void assertExpression(String expressionText, String expectedValue, String orThisExpectedValue) {
    Language language = assertResolveLanguage(getLanguageName());
    Expression expression = language.createExpression(expressionText);
    assertNotNull(expression, "No Expression could be created for text: " + expressionText + " language: " + language);
    Object value;
    if (expectedValue != null) {
        value = expression.evaluate(exchange, expectedValue.getClass());
    } else {
        value = expression.evaluate(exchange, Object.class);

    assertTrue(expectedValue.equals(value) || orThisExpectedValue.equals(value), "Expression: " + expression + " on Exchange: " + exchange);
}
