Enclosing class:

ThrottledInputStream

public static class ThrottledInputStream.Builder
extends AbstractStreamBuilder<T,B>

Builds a new ThrottledInputStream.

Using NIO

 ThrottledInputStream in = ThrottledInputStream.builder()
   .setPath(Paths.get("MyFile.xml"))
   .setMaxBytes(100_000, ChronoUnit.SECONDS)
   .get();
 
 

Using IO

 ThrottledInputStream in = ThrottledInputStream.builder()
   .setFile(new File("MyFile.xml"))
   .setMaxBytes(100_000, ChronoUnit.SECONDS)
   .get();
 
 

 ThrottledInputStream in = ThrottledInputStream.builder()
   .setInputStream(inputStream)
   .setMaxBytes(100_000, ChronoUnit.SECONDS)
   .get();

Constructor Detail

Builder

public Builder()

Constructs a new builder of ThrottledInputStream.

Method Detail

get

public ThrottledInputStream get()
                         throws java.io.IOException

Builds a new ThrottledInputStream.

You must set an aspect that supports AbstractStreamBuilder.getInputStream(), otherwise, this method throws an exception.

This builder uses the following aspects:

• AbstractStreamBuilder.getInputStream() gets the target aspect.
• maxBytesPerSecond

Returns:

a new instance.

Throws:

java.lang.IllegalStateException - if the origin is null.

java.lang.UnsupportedOperationException - if the origin cannot be converted to an InputStream.

java.io.IOException - if an I/O error occurs converting to an InputStream using AbstractStreamBuilder.getInputStream().

AbstractStreamBuilder.getInputStream(), IOSupplier.getUnchecked()

setMaxBytes

public ThrottledInputStream.Builder setMaxBytes(long value,
                                                java.time.temporal.ChronoUnit chronoUnit)

Sets the maximum bytes per time period unit.

For example, to throttle reading to 100K per second, use:

 builder.setMaxBytes(100_000, ChronoUnit.SECONDS)
 

To test idle timeouts for example, use 1 byte per minute, 1 byte per 30 seconds, and so on.

Parameters:

value - the maximum bytes

chronoUnit - a duration scale goal.

Returns:

this instance.

Throws:

java.lang.IllegalArgumentException - Thrown if maxBytesPerSecond <= 0.

Since:

2.19.0

setMaxBytesPerSecond

public void setMaxBytesPerSecond(long maxBytesPerSecond)

Sets the maximum bytes per second.

Parameters:

maxBytesPerSecond - the maximum bytes per second.

Throws:

java.lang.IllegalArgumentException - Thrown if maxBytesPerSecond <= 0.
