Method Details

eval

public Object eval(FormInstance model, EvaluationContext evalContext)

Specified by:

eval in class Triggerable

evalBool

public boolean evalBool(FormInstance model, EvaluationContext evalContext)

apply

public void apply(TreeReference ref, Object rawResult, FormInstance mainInstance)

Specified by:

apply in class Triggerable

canCascade

public boolean canCascade()

Specified by:

canCascade in class Triggerable

isCascadingToChildren

public boolean isCascadingToChildren()

Description copied from class: Triggerable

This should return true if this triggerable's targets will implicity modify the value of their children. IE: if this triggerable makes a node relevant/irrelevant, expressions which care about the value of this node's children should be triggered.

Overrides:

isCascadingToChildren in class Triggerable

Returns:

True if this condition should trigger expressions whose targets include nodes which are the children of this node's targets.

equals

public boolean equals(Object o)

Overrides:

equals in class Triggerable

readExternal

public void readExternal(DataInputStream in, PrototypeFactory pf) throws IOException, DeserializationException

Specified by:

readExternal in interface Externalizable

Overrides:

readExternal in class Triggerable

Throws:

IOException

DeserializationException

writeExternal

public void writeExternal(DataOutputStream out) throws IOException

Specified by:

writeExternal in interface Externalizable

Overrides:

writeExternal in class Triggerable

Throws:

IOException
