Method Details

schedule

public VarlenaWrapper.Verifier schedule()

Description copied from class: VarlenaWrapper.Verifier

Set up the verify method to be executed in another thread.

Overrides:

schedule in class VarlenaWrapper.Verifier

Returns:

This Verifier object.

update

public void update(InputStream is)
            throws SQLException

Description copied from class: VarlenaWrapper.Verifier

Send the next InputStream of content to be verified.

It is assumed, but not checked here, that any InputStream supplied to this method supports mark and reset efficiently.

If the verifier has already thrown an exception, it will be rethrown here in the current thread.

Overrides:

update in class VarlenaWrapper.Verifier

Parameters:

is - InputStream representing the next range of bytes to be verified.

Throws:

SQLException - if a verification error has already been detected, the verifier has been cancelled, etc.

update

public void update(org.postgresql.pljava.internal.VarlenaWrapper.Output.State state,
 ByteBuffer bb)
            throws SQLException

Description copied from class: VarlenaWrapper.Verifier

Convenience method that calls flip() on a byte buffer, wraps it in a BufferWrapper, and passes it to VarlenaWrapper.Verifier.update(java.io.InputStream).

Note that the NoOp version of this method does none of that; in particular, the byte buffer will not have been flipped. This should not be a problem, as the thread passing the buffer to this method had better make no further use of it anyway.

Overrides:

update in class VarlenaWrapper.Verifier

Parameters:

state - The state object protecting the native memory.

bb - Byte buffer containing next range of content to verify.

Throws:

SQLException - if a verification error has already been detected, the verifier has been cancelled, etc.

finish

public void finish()
            throws SQLException

Description copied from class: VarlenaWrapper.Verifier

Wait for the verify task and rethrow any exception it might have thrown.

Overrides:

finish in class VarlenaWrapper.Verifier

Throws:

SQLException - any exception thrown by the verify method, or for unexpected conditions such as interruption while waiting.

cancel

public void cancel()
            throws SQLException

Description copied from class: VarlenaWrapper.Verifier

Cancel this verifier.

Overrides:

cancel in class VarlenaWrapper.Verifier

Throws:

SQLException
