Method Detail

defaultOperation

public <S> Boolean defaultOperation(Object property,
                                    S literal,
                                    Class<S> literalClass,
                                    Enum operation)

These three Boolean operations AND, OR, and NOT are not boolean operations in the traditional sense They should return true if any of the operands are true. This is because we want the delegate to return true whenever VALIDATION_WARNINGS or VALIDATION_ERRORS occur in the filter For example: if we get a filter that is like [ validation-warnings is test ] AND [ AnyText is * ] we want and(java.util.List<java.lang.Boolean>) to return true, so we need an or operation underneath if we get a filter that is like [ validation-warnings is test ] OR [ AnyText is * ] we want or(java.util.List<java.lang.Boolean>) to return true, so we need an or operation underneath if we get a filter this is like NOT [ validation-warnings is test ] we want not(java.lang.Boolean) to return true, so we need to pass the operand as is

Overrides:

defaultOperation in class SimpleFilterDelegate<Boolean>

and

public Boolean and(List<Boolean> operands)

Description copied from class: FilterDelegate

Logical "and" operation on a list of operands.

Overrides:

and in class SimpleFilterDelegate<Boolean>

Parameters:

operands - list of operands to "and"

Returns:

result of "and" operation on operands

or

public Boolean or(List<Boolean> operands)

Description copied from class: FilterDelegate

Logical "or" operation on a list of operands.

Overrides:

or in class SimpleFilterDelegate<Boolean>

Parameters:

operands - list of T to "or"

Returns:

result of "or" operation on operands

not

public Boolean not(Boolean operand)

Description copied from class: FilterDelegate

Logical "not" operation on an operand.

Overrides:

not in class SimpleFilterDelegate<Boolean>

Parameters:

operand - operand to negate

Returns:

result of "not" operation on operand

propertyIsEqualTo

public Boolean propertyIsEqualTo(String propertyName,
                                 String literal,
                                 boolean isCaseSensitive)

Description copied from class: FilterDelegate

* See FilterDelegate.propertyIsEqualTo(String, Object).

Overrides:

propertyIsEqualTo in class SimpleFilterDelegate<Boolean>

Parameters:

propertyName - name of property to compare

literal - value to compare

isCaseSensitive - case-sensitivity boolean

Returns:

result of equals operation between propertyName and literal

See Also:

FilterDelegate.propertyIsEqualTo(String, Object)

propertyIsNull

public Boolean propertyIsNull(String propertyName)

Description copied from class: FilterDelegate

Compares the value associated with a property is equal to null.

propertyName == null

Overrides:

propertyIsNull in class SimpleFilterDelegate<Boolean>

Parameters:

propertyName - name of property to compare

Returns:

result of null check

propertyIsLike

public Boolean propertyIsLike(String propertyName,
                              String pattern,
                              boolean isCaseSensitive)

Description copied from class: FilterDelegate

Compares the value associated with a property to a regular expression pattern.

Regular expression special characters are defined as WILDCARD_CHAR, SINGLE_CHAR, and ESCAPE_CHAR.

Overrides:

propertyIsLike in class SimpleFilterDelegate<Boolean>

Parameters:

propertyName - name of property to compare

pattern - regular expression pattern to match

isCaseSensitive - case-sensitivity boolean

Returns:

result of regular expression operation

propertyIsEqualTo

public Boolean propertyIsEqualTo(String functionName,
                                 List<Object> arguments,
                                 Object literal)

Description copied from class: FilterDelegate

Compares the function return value is equal to the value of a literal. Filter delegates will have to know the function argument types and return types for each specific function in order to support it, therefore to simplify the API they are just passed as objects.

function result == literal

Overrides:

propertyIsEqualTo in class SimpleFilterDelegate<Boolean>

Parameters:

functionName - name of function

arguments - list of arguments to pass to the function

literal - value to compare

Returns:

result of equals operation between functionName result and literal
