public MetaDataStyleEvaluator()

Method Detail

getProcessingPriority

public int getProcessingPriority()

clone in class AbstractExpression

Returns:

a clone of this expression.

Throws:

CloneNotSupportedException - this should never happen.

getInstance

public MetaDataStyleEvaluator getInstance()

Description copied from class: AbstractExpression
