Field Detail

addDel

public int addDel

It denotes the delay of the addition.

mulDel

public int mulDel

It denotes the delay of the multiplication.

addId

public static final int addId

It denotes the identifier of the addition.

See Also:

Constant Field Values

mulId

public static final int mulId

It specifies the identifier of the multiplication.

See Also:

Constant Field Values

name

public java.lang.String name

It specifies the name of the filter.

dependencies

public int[][] dependencies

It specifies the dependencies between the operation. Each dependency is denoted by two element array. The first element of the array denotes the operation which must be executed before the operation denoted by the second element of the array.

ids

public int[] ids

It specifies the type of each operation of a given position.

last

public int[] last

It denotes the indexes of the operations on which no other operation depends on. The makespan of the schedule executing given filter depends on the maximal execution time of one of this operations.
