Examples with PreparedType com.google.cloud.spanner.pgadapter.wireprotocol.ControlMessage.PreparedType used on opensource projects

Example 1 with PreparedType

use of com.google.cloud.spanner.pgadapter.wireprotocol.ControlMessage.PreparedType in project pgadapter by GoogleCloudPlatform.

the class ProtocolTest method testCloseStatementMessage.

@Test
public void testCloseStatementMessage() throws Exception {
    byte[] messageMetadata = { 'C' };
    byte[] statementType = { 'S' };
    String statementName = "some statement\0";
    byte[] length = intToBytes(4 + statementType.length + statementName.length());
    byte[] value = Bytes.concat(messageMetadata, length, statementType, statementName.getBytes());
    String expectedStatementName = "some statement";
    PreparedType expectedType = PreparedType.Statement;
    DataInputStream inputStream = new DataInputStream(new ByteArrayInputStream(value));
    ByteArrayOutputStream result = new ByteArrayOutputStream();
    DataOutputStream outputStream = new DataOutputStream(result);
    when(connectionHandler.getStatement(anyString())).thenReturn(intermediatePortalStatement);
    when(connectionHandler.getConnectionMetadata()).thenReturn(connectionMetadata);
    when(connectionMetadata.getInputStream()).thenReturn(inputStream);
    when(connectionMetadata.getOutputStream()).thenReturn(outputStream);
    WireMessage message = ControlMessage.create(connectionHandler);
    assertEquals(CloseMessage.class, message.getClass());
    assertEquals(expectedStatementName, ((CloseMessage) message).getName());
    assertEquals(expectedType, ((CloseMessage) message).getType());
    verify(connectionHandler).getStatement("some statement");
    message.send();
    verify(connectionHandler).closeStatement(expectedStatementName);
    // CloseResponse
    DataInputStream outputResult = inputStreamFromOutputStream(result);
    assertEquals('3', outputResult.readByte());
    assertEquals(4, outputResult.readInt());
}

Example 2 with PreparedType

use of com.google.cloud.spanner.pgadapter.wireprotocol.ControlMessage.PreparedType in project pgadapter by GoogleCloudPlatform.

the class ProtocolTest method testClosePortalMessage.

@Test
public void testClosePortalMessage() throws Exception {
    byte[] messageMetadata = { 'C' };
    byte[] statementType = { 'P' };
    String statementName = "some portal\0";
    byte[] length = intToBytes(4 + statementType.length + statementName.length());
    byte[] value = Bytes.concat(messageMetadata, length, statementType, statementName.getBytes());
    String expectedStatementName = "some portal";
    PreparedType expectedType = PreparedType.Portal;
    DataInputStream inputStream = new DataInputStream(new ByteArrayInputStream(value));
    ByteArrayOutputStream result = new ByteArrayOutputStream();
    DataOutputStream outputStream = new DataOutputStream(result);
    when(connectionHandler.getPortal(anyString())).thenReturn(intermediatePortalStatement);
    when(connectionHandler.getConnectionMetadata()).thenReturn(connectionMetadata);
    when(connectionMetadata.getInputStream()).thenReturn(inputStream);
    when(connectionMetadata.getOutputStream()).thenReturn(outputStream);
    WireMessage message = ControlMessage.create(connectionHandler);
    assertEquals(CloseMessage.class, message.getClass());
    assertEquals(expectedStatementName, ((CloseMessage) message).getName());
    assertEquals(expectedType, ((CloseMessage) message).getType());
    verify(connectionHandler).getPortal("some portal");
    message.send();
    verify(intermediatePortalStatement).close();
    verify(connectionHandler).closePortal(expectedStatementName);
    // CloseResponse
    DataInputStream outputResult = inputStreamFromOutputStream(result);
    assertEquals('3', outputResult.readByte());
    assertEquals(4, outputResult.readInt());
