Method Detail

match

public boolean match(ServiceReference sr)

Description copied from interface: Filter

Filter using a service's properties.

This Filter is executed using the keys and values of the referenced service's properties. The keys are looked up in a case insensitive manner.

Specified by:

match in interface Filter

Parameters:

sr - The reference to the service whose properties are used in the match.

Returns:

true if the service's properties match this Filter; false otherwise.

match

public boolean match(java.util.Dictionary<java.lang.String,?> dctnr)

Description copied from interface: Filter

Filter using a Dictionary with case insensitive key lookup. This Filter is executed using the specified Dictionary's keys and values. The keys are looked up in a case insensitive manner.

Specified by:

match in interface Filter

Parameters:

dctnr - The Dictionary whose key/value pairs are used in the match.

Returns:

true if the Dictionary's values match this filter; false otherwise.

matchCase

public boolean matchCase(java.util.Dictionary<java.lang.String,?> dctnr)

Description copied from interface: Filter

Filter using a Dictionary. This Filter is executed using the specified Dictionary's keys and values. The keys are looked up in a normal manner respecting case.

Specified by:

matchCase in interface Filter

Parameters:

dctnr - The Dictionary whose key/value pairs are used in the match.

Returns:

true if the Dictionary's values match this filter; false otherwise.

matches

public boolean matches(java.util.Map<java.lang.String,?> map)

Description copied from interface: Filter

Filter using a Map. This Filter is executed using the specified Map's keys and values. The keys are looked up in a normal manner respecting case.

Specified by:

matches in interface Filter

Parameters:

map - The Map whose key/value pairs are used in the match. Maps with null key or values are not supported. A null value is considered not present to the filter.

Returns:

true if the Map's values match this filter; false otherwise.

equals

public boolean equals(java.lang.Object o)

Description copied from interface: Filter

Compares this Filter to another Filter.

This implementation returns the result of calling this.toString().equals(obj.toString()).

Specified by:

equals in interface Filter

Overrides:

equals in class java.lang.Object

Parameters:

o - The object to compare against this Filter.

Returns:

If the other object is a Filter object, then returns the result of calling this.toString().equals(obj.toString()); false otherwise.

hashCode

public int hashCode()

Description copied from interface: Filter

Returns the hashCode for this Filter.

This implementation returns the result of calling this.toString().hashCode().

Specified by:

hashCode in interface Filter

Overrides:

hashCode in class java.lang.Object

Returns:

The hashCode of this Filter.

toString

public java.lang.String toString()

Description copied from interface: Filter

Returns this Filter's filter string.

The filter string is normalized by removing whitespace which does not affect the meaning of the filter.

Specified by:

toString in interface Filter

Overrides:

toString in class java.lang.Object

Returns:

This Filter's filter string.
