Constructor Detail

SchemeEquals

public SchemeEquals(java.lang.String scheme)

Creates a filter that only accepts URIs with a given scheme.

Parameters:

scheme - the accepted scheme.

Method Detail

apply

public boolean apply(java.net.URI uri)

Apply the filter to a given URI

Parameters:

uri - the URI to be filtered

Returns:

true if uri has scheme equals to the inner string

valueOf

public static SchemeEquals valueOf(java.lang.String spec)

Get a new SchemeEquals accepting only URIs whose scheme equals the given string

Parameters:

spec - the scheme allowed

Returns:

A new SchemeEquals accepting only URIs whose scheme equals spec

toString

public java.lang.String toString()

A string representation of this

Overrides:

toString in class java.lang.Object

Returns:

the scheme allowed by this filter

equals

public boolean equals(java.lang.Object x)

Compare a given object with this

Specified by:

equals in interface com.google.common.base.Predicate<java.net.URI>

Overrides:

equals in class java.lang.Object

Parameters:

x - an object to be compared

Returns:

true if x is an instance of SchemeEquals and the scheme allowed by this is the same of the one allowed by x

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

copy

public Filter<java.net.URI> copy()
