org.trianacode.taskgraph.service.TypeChecking

public final class TypeChecking
extends java.lang.Object

TypeChecking includes several functions which check the validity of connections e.g. functions that check if an object is a TrianaType or not and others which check if two units are compatible.

Method Detail

isCompatibility

public static boolean isCompatibility(java.lang.Class[] outTypes,
                      java.lang.Class[] inTypes)

Returns true if any of the specified types output is compatibale with any of the specified input types. This is used to check whether a connection between two units can be valid

Parameters:

outTypes - the types sent out from the output unit.

inTypes - the types allowed to be input to the input unit.

Returns:

boolean True if any of the output types are consistent with any of the input types

isCompatible

public static boolean isCompatible(java.lang.Object sentObject,
                   java.lang.Class[] inTypes)

Returns true if the specified object is one of the allowed input types.

Parameters:

sentObject - the actual data object being sent.

inTypes - the types allowed to be input to the input unit.

Returns:

boolean True if the data being sent is an allowed input type

isCompatibility

public static boolean isCompatibility(Node sendnode,
                      Node recnode)

Returns true if the specified nodes can be legitimately be connected. This occurs when there is type compatibility between the tasks, or one/both of the nodes are parameter nodes.

floatArrayToDouble

public static double[] floatArrayToDouble(float[] from)

classForTrianaType

public static java.lang.Class classForTrianaType(java.lang.String name)

This function attempts to return the class representation for the the given name of the Triana type. If prepends triana.types to start of the name and looks for the class representation.

classForTrianaType

public static java.lang.Class[] classForTrianaType(java.lang.String[] types)

Attempts to convert the array of objects (Strings actually) to TrianaTypes
