Method Detail

getInstance

public static EmptyAttributeMap getInstance()

size

public int size()

Return the number of attributes in the map.

Specified by:

size in interface AttributeMap

Returns:

The number of attributes in the map.

get

public AttributeInfo get(NodeName name)

Description copied from interface: AttributeMap

Get the attribute with a given name, if it exists

Specified by:

get in interface AttributeMap

Parameters:

name - the name of the required attribute

Returns:

the required attribute if it exists

get

public AttributeInfo get(java.lang.String uri,
                         java.lang.String local)

Description copied from interface: AttributeMap

Get the attribute with a given name, if it exists

Specified by:

get in interface AttributeMap

Parameters:

uri - the namespace part of the name of the required attribute

local - the local part of the name of the required attribute

Returns:

the required attribute if it exists

getByFingerprint

public AttributeInfo getByFingerprint(int fingerprint,
                                      NamePool namePool)

Specified by:

getByFingerprint in interface AttributeMap

put

public AttributeMap put(AttributeInfo att)

Description copied from interface: AttributeMap

Replace or add an attribute, to create a new AttributeMap

Specified by:

put in interface AttributeMap

Parameters:

att - the attribute to be added or replaced

Returns:

the new AttributeMap

remove

public AttributeMap remove(NodeName name)

Description copied from interface: AttributeMap

Remove an existing attribute, to create a new AttributeMap

Specified by:

remove in interface AttributeMap

Parameters:

name - the name of the attribute to be removed (if it exists)

Returns:

a new attribute map in which the specified attribute is omitted. If the attribute map contains no attribute with the given name, the input attribute map (or one equivalent to it) is returned unchanged

Specified by:

iterator in interface java.lang.Iterable<AttributeInfo>

apply

public AttributeMap apply(java.util.function.Function<AttributeInfo,AttributeInfo> mapper)

Specified by:
