Constructor Detail

MetaDataStyleEvaluator

public MetaDataStyleEvaluator()

Method Detail

getDependencyLevel

public int getDependencyLevel()

Returns the dependency level for the expression (controls evaluation order for expressions and functions).

Specified by:

getDependencyLevel in interface Expression

Overrides:

getDependencyLevel in class AbstractExpression

Returns:

the level.

getProcessingPriority

public int getProcessingPriority()

Specified by:

getProcessingPriority in interface StructureFunction

getAttributeContext

public org.pentaho.reporting.engine.classic.core.function.sys.MetaDataStyleEvaluator.VolatileDataAttributeContext getAttributeContext()

clone

public Object clone()
             throws CloneNotSupportedException

Clones the expression. The expression should be reinitialized after the cloning.

Expressions maintain no state, cloning is done at the beginning of the report processing to disconnect the expression from any other object space.

Specified by:

clone in interface Expression

Overrides:

clone in class AbstractExpression

Returns:

a clone of this expression.

Throws:

CloneNotSupportedException - this should never happen.

getInstance

public Expression getInstance()

Description copied from class: AbstractExpression

Return a completly separated copy of this function. The copy does no longer share any changeable objects with the original function.

Specified by:

getInstance in interface Expression

Overrides:

getInstance in class AbstractExpression

Returns:

a copy of this function.
