Field Detail

_sensitive

protected boolean _sensitive

A sensitive command is one that should be guarded against inadvertant invocation. Its cost is high and undoing is difficult. A ui is advised to make it difficult for an end user to inadvertantly invoke the command.

public abstract void execute(java.lang.Object value,
                             EView source)
                      throws java.lang.reflect.InvocationTargetException

Throws:

java.lang.reflect.InvocationTargetException

isSensitive

public boolean isSensitive()

setSensitive

public void setSensitive(boolean sensitive)

forbid

public void forbid()

allow

public void allow()

isForbidden

public boolean isForbidden()

applyRestriction

public void applyRestriction(Restriction restriction)

Specified by:

applyRestriction in interface Restrictable

liftRestriction

public void liftRestriction(Restriction restriction)

Specified by:

liftRestriction in interface Restrictable

setOwner

public void setOwner(Field ownerField)

getOwner

public User getOwner(ComplexEObject parent)

finder

public static SimpleFinder finder(java.lang.String commandName)

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class AbstractComplexEObject

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

isOpenInNonMinimizedContext

public boolean isOpenInNonMinimizedContext(EView source)

basically a guard against grafting the "Open" command on maximized views

isMinorCommand

public boolean isMinorCommand(EView source)
