Example 15 with StatementContext

use of org.apache.phoenix.compile.StatementContext in project phoenix by apache.

the class PhoenixMetricsIT method changeInternalStateForTesting.

private void changeInternalStateForTesting(PhoenixResultSet rs) {
    // get and set the internal state for testing purposes.
    ReadMetricQueue testMetricsQueue = new TestReadMetricsQueue(true);
    StatementContext ctx = (StatementContext) Whitebox.getInternalState(rs, "context");
    Whitebox.setInternalState(ctx, "readMetricsQueue", testMetricsQueue);
    Whitebox.setInternalState(rs, "readMetricsQueue", testMetricsQueue);
