Examples with ArrayLiteral io.crate.sql.tree.ArrayLiteral used on opensource projects

Example 1 with ArrayLiteral

use of io.crate.sql.tree.ArrayLiteral in project crate by crate.

the class GenericPropertiesConverter method genericPropertyToSetting.

/**
     * Put a genericProperty into a settings-structure
     */
static void genericPropertyToSetting(Settings.Builder builder, String name, Expression value, Row parameters) {
    if (value instanceof ArrayLiteral) {
        ArrayLiteral array = (ArrayLiteral) value;
        List<String> values = new ArrayList<>(array.values().size());
        for (Expression expression : array.values()) {
            values.add(ExpressionToStringVisitor.convert(expression, parameters));
        }
        builder.putArray(name, values.toArray(new String[values.size()]));
    } else {
        builder.put(name, ExpressionToStringVisitor.convert(value, parameters));
    }
}

Example 2 with ArrayLiteral

use of io.crate.sql.tree.ArrayLiteral in project crate by crate.

    assertThat(emptyArrayLiteral.values().size(), is(0));
    ArrayLiteral singleArrayLiteral = (ArrayLiteral) SqlParser.createExpression("[1]");
    assertThat(singleArrayLiteral.values().size(), is(1));
    assertThat(singleArrayLiteral.values().get(0), instanceOf(IntegerLiteral.class));
    ArrayLiteral multipleArrayLiteral = (ArrayLiteral) SqlParser.createExpression("['str', -12.56, {}, ['another', 'array']]");
