columnNameForBinaryData - the name of the column used to store image data

Method Detail

getTranslation

protected java.lang.String getTranslation(java.lang.String resourceKey)

Returns a text in the corresponding language according to the locale specific resource bundle of the package.

Parameters:

resourceKey - the key of the resource to retrieve

Returns:

the resource

setUseWinCopyIfPossible

public void setUseWinCopyIfPossible(boolean useWinCopyIfPossible)

getAssignedDataObject

public DataObject getAssignedDataObject()

Returns the assigned data object.

Specified by:

getAssignedDataObject in interface DataComponent

Returns:

the assigned data object

setRequired

public void setRequired(boolean required)

Determines whether input is required (mandatory).

Specified by:
