Examples with ParserContext org.springframework.expression.ParserContext used on opensource projects

Example 1 with ParserContext

use of org.springframework.expression.ParserContext in project camel by apache.

the class SpelExpression method parseExpression.

private Expression parseExpression() {
    // Support template parsing with #{ } delimiters
    ParserContext parserContext = new TemplateParserContext();
    Expression expression = expressionParser.parseExpression(expressionString, parserContext);
    return expression;
}

Example 2 with ParserContext

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

the class TemplateExpressionParsingTests method testTemplateParserContext.

@Test
public void testTemplateParserContext() {
    TemplateParserContext tpc = new TemplateParserContext("abc", "def");
    assertThat(tpc.getExpressionPrefix()).isEqualTo("abc");
    assertThat(tpc.getExpressionSuffix()).isEqualTo("def");
    assertThat(tpc.isTemplate()).isTrue();
    tpc = new TemplateParserContext();
    assertThat(tpc.getExpressionPrefix()).isEqualTo("#{");
    assertThat(tpc.getExpressionSuffix()).isEqualTo("}");
    assertThat(tpc.isTemplate()).isTrue();
    ParserContext pc = ParserContext.TEMPLATE_EXPRESSION;
    assertThat(pc.getExpressionPrefix()).isEqualTo("#{");
    assertThat(pc.getExpressionSuffix()).isEqualTo("}");
    assertThat(pc.isTemplate()).isTrue();
}
