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.
