javax.swing.undo.AbstractUndoableEdit — clojure-interop/javax.swing 1.0.5

An abstract implementation of UndoableEdit, implementing simple responses to all boolean methods in that interface.

->abstract-undoable-edit clj

(->abstract-undoable-edit)

Constructor.

Creates an AbstractUndoableEdit which defaults hasBeenDone and alive to true.

add-edit clj

(add-edit this an-edit)

This default implementation returns false.

an-edit - the edit to be added - javax.swing.undo.UndoableEdit

returns: false - boolean

can-redo? clj

(can-redo? this)

Returns true if this edit is alive and hasBeenDone is false.

returns: true if this edit is alive and hasBeenDone is false - boolean

can-undo? clj

(can-undo? this)

Returns true if this edit is alive and hasBeenDone is true.

returns: true if this edit is alive and hasBeenDone is true - boolean

die clj

(die this)

Sets alive to false. Note that this is a one way operation; dead edits cannot be resurrected. Sending undo or redo to a dead edit results in an exception being thrown.

Typically an edit is killed when it is consolidated by another edit's addEdit or replaceEdit method, or when it is dequeued from an UndoManager.

get-presentation-name clj

(get-presentation-name this)

This default implementation returns "". Used by getUndoPresentationName and getRedoPresentationName to construct the strings they return. Subclasses should override to return an appropriate description of the operation this edit represents.

returns: the empty string "" - java.lang.String

get-redo-presentation-name clj

(get-redo-presentation-name this)

Retreives the value from the defaults table with key AbstractUndoableEdit.redoText and returns that value followed by a space, followed by getPresentationName. If getPresentationName returns "", then the defaults value is returned alone.

returns: the value from the defaults table with key AbstractUndoableEdit.redoText, followed by a space, followed by getPresentationName unless getPresentationName is "" in which case, the defaults value is returned alone. - java.lang.String

get-undo-presentation-name clj

(get-undo-presentation-name this)

Retreives the value from the defaults table with key AbstractUndoableEdit.undoText and returns that value followed by a space, followed by getPresentationName. If getPresentationName returns "", then the defaults value is returned alone.

returns: the value from the defaults table with key AbstractUndoableEdit.undoText, followed by a space, followed by getPresentationName unless getPresentationName is "" in which case, the defaults value is returned alone. - java.lang.String

redo clj

(redo this)

Throws CannotRedoException if canRedo returns false. Sets hasBeenDone to true. Subclasses should override to redo the operation represented by this edit. Override should begin with a call to super.

throws: javax.swing.undo.CannotRedoException - if canRedo returns false

replace-edit clj

(replace-edit this an-edit)

This default implementation returns false.

an-edit - the edit to replace - javax.swing.undo.UndoableEdit

returns: false - boolean

significant? clj

(significant? this)

This default implementation returns true.

returns: true - boolean

to-string clj

(to-string this)

Returns a string that displays and identifies this object's properties.

returns: a String representation of this object - java.lang.String

undo clj

(undo this)

Throws CannotUndoException if canUndo returns false. Sets hasBeenDone to false. Subclasses should override to undo the operation represented by this edit. Override should begin with a call to super.

throws: javax.swing.undo.CannotUndoException - if canUndo returns false
