Constructor Detail

ReadOnlyBufferControlDelegate

public ReadOnlyBufferControlDelegate(javax.media.control.BufferControl bufferControl)

Initializes a new ReadOnlyBufferControlDelegate instance which is to wrap a specific BufferControl and call only its getters.

Parameters:

bufferControl - the BufferControl to be wrapped by the new instance

Method Detail

getBufferLength

public long getBufferLength()

Implements BufferControl.getBufferLength(). Gets the length in milliseconds of the buffering performed by the owner of the wrapped BufferControl.

Specified by:

getBufferLength in interface javax.media.control.BufferControl

Returns:

the length in milliseconds of the buffering performed by the owner of the wrapped BufferControl

getControlComponent

public Component getControlComponent()

Implements Control.getControlComponent(). Gets the UI Component representing this instance and exported by the owner of the wrapped BufferControl.

Specified by:

getControlComponent in interface javax.media.Control

Returns:

the UI Component representing the wrapped BufferControl and exported by its owner if such a Component is available; otherwise, null

getEnabledThreshold

public boolean getEnabledThreshold()

Implements BufferControl.getEnabledThreshold(). Gets the indicator of the wrapped BufferControl which determines whether threshold calculations are enabled.

Specified by:

getEnabledThreshold in interface javax.media.control.BufferControl

Returns:

true if threshold calculations are enabled in the wrapped BufferControl; otherwise, false

getMinimumThreshold

public long getMinimumThreshold()

Implements BufferControl.getMinimumThreshold(). Gets the minimum threshold in milliseconds for the buffering performed by the owner of the wrapped BufferControl.

Specified by:

getMinimumThreshold in interface javax.media.control.BufferControl

Returns:

the minimum threshold in milliseconds for the buffering performed by the owner of the wrapped BufferControl

setBufferLength

public long setBufferLength(long bufferLength)

Implements BufferControl.setBufferLength(long). Ignores the request because this instance provides read-only support and returns the value actually in effect.

Specified by:

setBufferLength in interface javax.media.control.BufferControl

Parameters:

bufferLength - the length in milliseconds of the buffering to be performed by the owner of the wrapped BufferControl

Returns:

the length in milliseconds of the buffering performed by the owner of the wrapped BufferControl that is actually in effect

setEnabledThreshold

public void setEnabledThreshold(boolean enabledThreshold)

Implements BufferControl.setEnabledThreshold(boolean). Ignores the set request because this instance provides read-only support.

Specified by:

setEnabledThreshold in interface javax.media.control.BufferControl

Parameters:

enabledThreshold - true if threshold calculations are to be enabled; otherwise, false

setMinimumThreshold

public long setMinimumThreshold(long minimumThreshold)

Implements BufferControl.setMinimumThreshold(long). Ignores the set request because this instance provides read-only support and returns the value actually in effect.

Specified by:

setMinimumThreshold in interface javax.media.control.BufferControl

Parameters:

minimumThreshold - the minimum threshold in milliseconds for the buffering to be performed by the owner of the wrapped BufferControl

Returns:

the minimum threshold in milliseconds for the buffering performed by the owner of the wrapped BufferControl that is actually in effect
