All Implemented Interfaces:

MatchRuleVisitor

public class MatchRulePrinter
extends java.lang.Object
implements MatchRuleVisitor

Converts a MatchRule to a String using the default syntax. The only necessary method to call is:

asString( matchRule )

MatchRulePrinter

public MatchRulePrinter()

Initialize the new instance with default values.

MatchRulePrinter

public MatchRulePrinter(MatchRuleChars ruleCharacters)

Initialize the new instance with match rule characters.

useNewSyntax

public boolean useNewSyntax()

Returns true, if the printer uses the new syntax which is using an equals character rather than the curly brackets for single values.
The default is NOT to use the new syntax to be compatible to old usage.

useNewSyntax

public void useNewSyntax(boolean newValue)

Sets if the printer uses the new syntax.

walkThroughInit

public void walkThroughInit()

This method will be called right before the MatchRule walks through its elements.

Specified by:

walkThroughInit in interface MatchRuleVisitor

walkThroughFinished

public void walkThroughFinished()

This method will be called when the MatchRule has finished to walk through its elements.

Specified by:

walkThroughFinished in interface MatchRuleVisitor

startGroup

public void startGroup(boolean andOperator,
                       boolean notOperator)

This method will be called for each start of a new group.

Specified by:

startGroup in interface MatchRuleVisitor

Parameters:

andOperator - If true it is an AND combination otherwise it is OR

notOperator - Is only true for a NOT operation

endGroup

public void endGroup()

This method will be called for each group end occurence.

Specified by:

endGroup in interface MatchRuleVisitor

attribute

public void attribute(java.lang.String name,
                      MatchRuleCompareOperator compareOperator,
                      java.lang.String[] values,
                      boolean andOperator,
                      boolean notOperator)

This method will be called for each attribute.

Specified by:

attribute in interface MatchRuleVisitor

Parameters:

name - The attribute's name

compareOperator - The operator used to compare values

values - All values the attrubute my match (implicit OR combination !)

andOperator - If true it is an AND combination otherwise it is OR

notOperator - Is only true for a NOT operation
