Method Details

memoType

protected static MemoType memoType(String shortName)

checkUser

protected void checkUser(SystemUser who)

isViewMode

protected boolean isViewMode()

execute

public void execute(View lock)

Description copied from interface: ExecutableView

Execute the associated view by locking another view (the locked view will not be selectable until this view is closed). The locked view acts as its "parent" and it will automatically get selected when this view closes.

Specified by:

execute in interface ExecutableView

Parameters:

lock - View to be locked.

checkMemoType

protected void checkMemoType(MemoType type)

getMemoLabel

protected String getMemoLabel()

getCreateLabel

protected String getCreateLabel()

getApproveLabel

protected String getApproveLabel()

includeColumn

public boolean includeColumn(String columnName)

Description copied from interface: HasColumns

Determines the respective column should be created or note. This is useful when columns are autogenerated, but you want to eliminate some columns.

Specified by:

includeColumn in interface HasColumns<MemoComment>

Parameters:

columnName - Column name

Returns:

Default implementation returns true for all columns.

memoLoadFilter

protected String memoLoadFilter()

loadMemos

protected <M extends Memo> void loadMemos()

memoClass

protected final <M extends Memo> Class<M> memoClass()

filter

protected boolean filter(Memo memo)

filter

protected boolean filter(MemoComment memoComment)

createHeader

public final com.vaadin.flow.component.Component createHeader()

Description copied from interface: HasColumns

You can have a "header row" (as the first row) that covers the whole grid. Typically, such a row is to show your own buttons or components to customize the grid. The default implementation returns null, and thus, no such row is created. (Please note that HasColumns.createHeaders()} is invoked before this method for adding other header rows just above the main header row. This may be used for column grouping etc.)

Specified by:

createHeader in interface HasColumns<MemoComment>

Returns:

Component to be used as the "header row".

addExtraButtons

protected void addExtraButtons()

whoName

protected String whoName(SystemUser who)

createHeaders

public void createHeaders()

Description copied from interface: HasColumns

Create extra header rows if required here by invoking HasColumns.prependHeader() or HasColumns.appendHeader() (typically useful for creating column grouping etc.). The default implementation does nothing. This is invoked before HasColumns.createHeader().

Specified by:

createHeaders in interface HasColumns<MemoComment>

whoButton

protected final void whoButton()

assistantMessage

protected String assistantMessage(SystemUser who)

addToHeader

protected void addToHeader(ButtonLayout buttonLayout)

loaded

public void loaded()

Description copied from class: ObjectListGrid

This method will be invoked whenever data is loaded.

Overrides:

loaded in class ObjectListGrid<MemoComment>

clean

public void clean()

Description copied from interface: ExecutableView

Clean this up by closing resources if any.

Specified by:

clean in interface ExecutableView

executeAndLoad

public void executeAndLoad()

getCommentedAt

public String getCommentedAt(MemoComment mc)

viewMemo

public void viewMemo()

getUser

protected SystemUser getUser()

createMemoEditor

protected <M extends Memo> MemoSystem.MemoEditor<M> createMemoEditor(Class<M> memoClass)

selectWho

protected void selectWho()

handleAlert

public void handleAlert(StoredObject memo)

Description copied from interface: AlertHandler

Handle the alert.

Specified by:

handleAlert in interface AlertHandler

Parameters:

memo - Associated object instance.

handleAlert

public void handleAlert(Id id)

Description copied from interface: AlertHandler

Handle the alert.

Specified by:

handleAlert in interface AlertHandler

Parameters:

id - Id of the associated object instance.
