LabelGraphicsParser

public LabelGraphicsParser()

Method Detail

setAttributes

public void setAttributes(java.util.Map attributes)

Sets the internally used attribute map.

resetItem

public void resetItem()

Resets the internally help attribute map.

commitValues

public void commitValues(YLabel label)

Commits the parsed values to a YLabel instance.

decodeType

protected java.lang.String decodeType(java.lang.String externalName)

Returns the qualified class name for the given external name.

By default, this method delegates to YGFIOHandler.decode(String).

Note: To prevent obfuscation from breaking user data serialization, an explicit class name encoding should be specified for user data types.
