PropertyIsLikeOperation

public PropertyIsLikeOperation(PropertyName propertyName,
                               Literal literal,
                               char wildCard,
                               char singleChar,

Method Detail

getWildCard

public char getWildCard()

Returns:

the wildcard

getSingleChar

public char getSingleChar()

Returns:

the singleChar

getEscapeChar

public char getEscapeChar()

Returns:

the escape character

isMatchCase

public boolean isMatchCase()

Returns:

matchCase flag

buildFromDOM

public static Operation buildFromDOM(Element element)
                              throws FilterConstructionException

Given a DOM-fragment, a corresponding Operation-object is built. This method recursively calls other buildFromDOM () - methods to validate the structure of the DOM-fragment.

Parameters:

element - the element to parse

Returns:

a Bean of the DOM

Throws:

FilterConstructionException - if the structure of the DOM-fragment is invalid

getPropertyName

public PropertyName getPropertyName()

Returns:

the name of the property that shall be compared to the literal

getLiteral

public Literal getLiteral()

Returns:

the literal the property shall be compared to

toXML

public StringBuffer toXML()

Produces an indented XML representation of this object.

evaluate

public boolean evaluate(Feature feature)
                 throws FilterEvaluationException

Calculates the PropertyIsLike's logical value based on the certain property values of the given Feature.

Parameters:

feature - that determines the property values

Returns:

true, if the Literal matches the PropertyName's value

Throws:

FilterEvaluationException - if the evaluation could not be performed (for example a specified Property did not exist)

matches

public boolean matches(String pattern,
                       String buffer)

Checks if a given String matches a pattern that is a sequence of:

• standard characters
• wildcard characters (like * in most shells)
• singlechar characters (like ? in most shells)

Parameters:

pattern - the pattern to compare to

buffer - the String to test

Returns:

true, if the String matches the pattern
