Method Detail

copy

public AttributeExtractor copy()

Description copied from class: AttributeExtractor

This method returns a copy of an AttributeExtractor. This is useful to use multiple extractors in parallel or distributed environments as AttributeExtractors can be stateful.

Specified by:

copy in class AttributeExtractor

Returns:

calculate

public AudioFeature calculate(java.lang.Object input)
                       throws java.io.IOException,
                              java.lang.IllegalArgumentException

Description copied from class: AttributeExtractor

This method encapsulates the attribute extraction process. The input parameter is open, because of the very general design of AttributeExtractor and Attribute. A concrete class implementing this interface will however expect the input to be of a certain type and will raise a IllegalArgumentException, if the passed argument is not of the expected type.

Specified by:

calculate in class AttributeExtractor

Parameters:

input - Object an object representing the input data to extract the feature out of

Returns:

Feature a feature extracted from the input data

Throws:

java.io.IOException - failures due to io operations are signaled by IOExceptions

java.lang.IllegalArgumentException - raised if method contract is violated, especially if the open input type is not of the expected type

getAttributeType

public int getAttributeType()

Description copied from class: AttributeExtractor

Returns the type of the attribute that the class implementing this interface will return as the result of its extraction process. By definition this is the hash code of the attribute's class name.

Specified by:

getAttributeType in class AttributeExtractor

Returns:

int an integer uniquely identifying the returned Attribute

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
