Field Detail

value

protected double value

the double value the supplied objects are matched against.

Constructor Detail

DoubleFilter

public DoubleFilter()

Constructs a DoubleFilter.

DoubleFilter

public DoubleFilter(double d)

Constructs a DoubleFilter.

Method Detail

accept

public boolean accept(double i)

Matches the double value i against the current filter.

Parameters:

i - the double to match

Returns:

true if the value matched

accept

public boolean accept(Object value)

Decides whether to accept the value supplied.

Specified by:

accept in class Filter

Parameters:

value - the object we want to decide if it will be filtered or not.

Returns:

true if the object matched and should not be filtered out, false otherwise.

fromString

public boolean fromString(String str)

Parses the supplied string to a Number and returns a boolean indicating if the parsing was successful.

Specified by:

fromString in class NumberFilter

Parameters:

str - the string to parse to a Number

Returns:

true if the supplied string was successfully parsed, false otherwise.

getFilterPattern

public Object getFilterPattern()

Returns the object used as the filter pattern.

Specified by:

getFilterPattern in class Filter

Returns:

the object that is currently set as the filter pattern.

getNumber

public Number getNumber()

Returns the Number object which is set as the filter pattern.

Specified by:

getNumber in class NumberFilter

Returns:

the filter pattern as a Number

setDouble

public void setDouble(double i)

Sets the double value used to match against Number objects.

Parameters:

i - the double value filter.

setFilterPattern

public void setFilterPattern(Object filter)

Sets an object as the filter pattern. Subclasses should provide an implementation that will probably first cast filter to the appropriate object.

Specified by:

setFilterPattern in class Filter

Parameters:

filter - the object to set as the filter pattern

setNumber

public void setNumber(Number n)

Assigns a new Number object as the filter pattern.

Specified by:

setNumber in class NumberFilter

Parameters:

n - the new filter pattern to assign as a Number.
