Method Detail

isAssignableFrom

public boolean isAssignableFrom(Var<?> source)

Description copied from class: Var

Checks whether the type of the given variable is equal or extends this variable's type.
If the result is true, then the given variable can become a link source for this variable

Overrides:

isAssignableFrom in class Var<N extends java.lang.Number>

Returns:

true if the source type is equal or wider than this variable's type, false otherwise (including if source has null type)

createVarEditor

public VarEditor<N> createVarEditor()

Description copied from class: Var

Creates a new VarEditor object that allows the user to graphically adjust the value of this variable. By default this editor is an empty label for generic types, but this method can be overridden to provide a custom editor.

Overrides:

createVarEditor in class Var<N extends java.lang.Number>

Returns:

the variable editor embarking the graphical component
