Method Detail

getValue

public Object getValue(long timestamp)

Gets the value for the given controlled property at the requested time.

Parameters:

timestamp - the time the control-change should be read from

Returns:

the value of the property at the given time, or NULL if the property isn't controlled

getValueArray

public boolean getValueArray(long timestamp,
                             long interval,
                             Object[] values)

Gets a number of values for the given controlled property starting at the requested time.

This function is useful if one wants to e.g. draw a graph of the control curve or apply a control curve sample by sample.

Parameters:

timestamp - the time that should be processed

interval - the time spacing between subsequent values

values - array to fill with control values

Returns:

false if the given array could not be filled

setDisabled

public void setDisabled(boolean disabled)

This function is used to disable a control binding for some time, i.e. GstObject.syncValues() will do nothing.

Parameters:

disabled - whether to disable the controller or not

isDisabled

public boolean isDisabled()

Check if the control binding is disabled.

Returns:

TRUE if the binding is inactive
