Rule

public Rule(Pattern pattern,
            Action action)

Rule

public Rule(Rule that,
            Pattern pattern)

Constructs a new Rule with the same instance data as the given rule but a different pattern.

Parameters:

that - DOCUMENT ME!

pattern - DOCUMENT ME!

equals

public boolean equals(Object that)

hashCode

public int hashCode()

compareTo

public int compareTo(Object that)

Specified by:

compareTo in interface Comparable

compareTo

public int compareTo(Rule that)

Compares two rules in XSLT processing model order assuming that the modes are equal.

Parameters:

that - DOCUMENT ME!

Returns:

DOCUMENT ME!

toString

public String toString()

matches

public final boolean matches(Node node)

DOCUMENT ME!

Parameters:

node - DOCUMENT ME!

Returns:

true if the pattern matches the given DOM4J node.

getUnionRules

public Rule[] getUnionRules()

If this rule contains a union pattern then this method should return an array of Rules which describe the union rule, which should contain more than one rule. Otherwise this method should return null.

Returns:

an array of the rules which make up this union rule or null if this rule is not a union rule

getMatchType

public final short getMatchType()

DOCUMENT ME!

Returns:

the type of node the pattern matches which by default should return ANY_NODE if it can match any kind of node.

getMatchesNodeName

public final String getMatchesNodeName()

For patterns which only match an ATTRIBUTE_NODE or an ELEMENT_NODE then this pattern may return the name of the element or attribute it matches. This allows a more efficient rule matching algorithm to be performed, rather than a brute force approach of evaluating every pattern for a given Node.

Returns:

the name of the element or attribute this pattern matches or null if this pattern matches any or more than one name.

getMode

public String getMode()

Getter for property mode.

Returns:

Value of property mode.

setMode

public void setMode(String mode)

Setter for property mode.

Parameters:

mode - New value of property mode.

getImportPrecedence

public int getImportPrecedence()

Getter for property importPrecedence.

Returns:

Value of property importPrecedence.

setImportPrecedence

public void setImportPrecedence(int importPrecedence)

Setter for property importPrecedence.

Parameters:

importPrecedence - New value of property importPrecedence.

getPriority

public double getPriority()

Getter for property priority.

Returns:

Value of property priority.

setPriority

public void setPriority(double priority)

Setter for property priority.

Parameters:

priority - New value of property priority.

getAppearenceCount

public int getAppearenceCount()

Getter for property appearenceCount.

Returns:

Value of property appearenceCount.

setAppearenceCount

public void setAppearenceCount(int appearenceCount)

pattern - New value of property pattern.

getAction

public Action getAction()

Getter for property action.

Returns:

Value of property action.

setAction

public void setAction(Action action)

Setter for property action.

Parameters:

action - New value of property action.
