Package org.tensorics.core.lang

Class TensoricScript<E,T>

java.lang.Object

org.tensorics.core.lang.TensoricExpressionSupport<E>

org.tensorics.core.lang.TensoricScript<E,T>

Type Parameters:

E - the type of the elements of the field on which all the calculations are based on.

T - the type which shall be returned by the script, after it is executed (resolved)

All Implemented Interfaces:

java.io.Serializable, Expression<T>, Node

Direct Known Subclasses:

DoubleScript

public abstract class TensoricScript<E,T>
extends TensoricExpressionSupport<E>
implements Expression<T>, java.io.Serializable

This class is intended to be subclassed in order to describe calculations with tensorics, which shall be executed at a later time. This class itself inherits from TensoricExpressionSupport such that it provides the full capability of the eDSL.

To define a script, a field has to be given in the constructor, which describes all the operations which can be performed on its elements.

The script logic itself has to be implemented in the describe() method. To resolve a script, a ResolvingEngine has to be used.

Method Detail

describe

protected abstract Expression<T> describe()

getChildren

public java.util.List<Node> getChildren()

Description copied from interface: Node

Has to return the children of the node. This must never return null

Specified by:

getChildren in interface Node

Returns:

a list containing all the children of the node

isResolved

public boolean isResolved()

Description copied from interface: Expression

returns true if the expression contains a concrete value. Thus the method Expression.get() can be used to retrieve the actual value. If this method returns false, then the get method will throw an exception.

Specified by:

isResolved in interface Expression<E>

Returns:

true if the value can be retrieved, false otherwise.

get

public T get()

Description copied from interface: Expression

Retrieves the value of the expression. If the expression is deferred, then an expression will be thrown.

Specified by:

get in interface Expression<E>

Returns:

the value of the expression.

getInternalExpression

public Expression<T> getInternalExpression()

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
